GATT SERVICE VIEW WHEN CONNECTED DS50002547A-page 23 RN4870/71 PICtailTM/PICtail Plus Daughter Board User's Guide FIGURE 3-9: 3.5 CONNECTED STATUS MESSAGE CREATING CUSTOM GATT SERVICES The RN4870/71 module supports custom (or private) GATT services. Public GATT services are defined by specifications published by the Bluetooth Special Interest Group (SIG). Private GATT services are defined by the user to host information stored in the GATT characteristics. For more information on GATT services, refer to Appendix C. "Bluetooth Low Energy Primer". To create a private GATT service, enter the configuration commands listed in Step 3. The commands can be entered as shown in this user guide, or copied from configuration files and pasted into the terminal emulator. The cut and paste method saves time and minimizes keyboard entry errors. The configuration text files are included in the RN4870 Sensor board Support package that can be downloaded from the product web page at www.microchip.com/RN4870. 1. Connect the RN4870 PICtail to the host PC USB port a) Using Terminal Emulator, open the COM port to the RN4870/71 module b) Type $$$ to enter Command mode c) Enter + to turn on ECHO 2. Set Factory Default values a) Enter SF,1 b) Verify that the module reboots after the command is entered 3. Create the private GATT service with three characteristics by entering the following commands: PS,4D6963726F636869702D524E34383730 PC,BF3FBD80063F11E59E690002A5D5C501,02,02 PC,BF3FBD80063F11E59E690002A5D5C502,02,02 PC,BF3FBD80063F11E59E690002A5D5C503,18,04 These commands can be entered manually by typing each line followed by the <Enter> key from the file 3.4-GATT-service.txt, or each line copied and pasted one by one into the terminal emulator. Command PS creates the GATT service, identified by the 16-byte value private UUID: 4D6963726F636869702D524E34383730. This command must be called before command PC. Command PC sets the private characteristics. Each characteristic is identified by the following UUIDs: BF3FBD80063F11E59E690002A5D5C501, BF3FBD80063F11E59E690002A5D5C502, BF3FBD80063F11E59E690002A5D5C503. DS50002547A-page 24 2016 Microchip Technology Inc. Command PC expects three parameters. The first parameter is the UUID, the second parameter is the characteristic property (refer to Table C-1 in Appendix C. "Bluetooth Low Energy Primer"), and the third parameter is the size of the data value of the characteristic. 4. Reboot the module using command R,1 to ensure that the new GATT service takes effect 5. Verify that the GATT service is correctly configured. 6. Enter Command mode ($$$) after rebooting the module. 7. Issue the LS command to list the GATT server services and their characteristics. The response is illustrated in Figure 3-10. FIGURE 3-10: 3.6 PRIVATE SERVICES DISPLAY FROM LS COMMAND ACCESSING GATT SERVICE USING UART COMMANDS AND SMARTDISCOVER APP The result of the command LS is shown in Figure 3-10. A custom GATT service (UUID: 4D6963726F636869702D524E34383730) with three characteristics identified by low-order bytes C501, C502 and C503 from the 128-bit UUID. A 16-bit handle is assigned to each characteristic. Handles are used to reference and identify 128-bit characteristic UUIDs more efficiently in the GATT service. Note that there are two references for C503 characteristic. In the first case, in reference 0076, the property value 08 has the write property enabled (refer to Table C-1 in Appendix C. "Bluetooth Low Energy Primer"). Likewise, reference 0077 has the notification property 10 enabled. This means that to write a value to characteristic C503, reference 0076 is used. To enable Client notifications on this characteristic, reference 0077 is used. The following examples show how to read and write GATT characteristic values by using UART commands: 1. To write a value to the GATT Server characteristic C501, use the Server Handle Write (SHW) and the Server Handle Read (SHR) commands with reference 0072 as first parameter, following by hex-byte values as shown in Figure 3-11. 2016 Microchip Technology Inc. DS50002547A-page 25 RN4870/71 PICtailTM/PICtail Plus Daughter Board User's Guide FIGURE 3-11: WRITING AND READING GATT VALUE BY HANDLE REFERENCE 2. It is also possible to access the GATT server over a Bluetooth Low Energy connection using SmartDiscover App. Launch the SmartDiscover App and connect to the RN4870/71 PICtail/PICtail Plus Daughter board configured with the private GATT as shown in Section 3.5 "Creating Custom GATT Services". In this example, the device "BLE-C071" is used. Follow the steps in Figure 3-12 to read the value of the GATT characteristic C501. In steps 1 and 2, tap on the name of your device (BLE-C071 >), on the UUID (BF3FBD80063F11E59E690002A5D5C501 and on Read in step 3. The characteristic value is read from the RN4870/71 into the Smart Discover App. FIGURE 3-12: DS50002547A-page 26 USING SMARTDISCOVER TO READ GATT CHARACTERISTIC VALUE 2016 Microchip Technology Inc. 3.7 READING SENSOR BOARD PERIPHERAL IO PORTS USING UART COMMANDS The RN4870/71 module has digital and analog peripheral inputs and outputs.

After the IO ports are configured and the module is rebooted, perform the commands shown in Figure 3-14 to read and write peripheral IO. FIGURE 3-14: DS50002547A-page 28 COMMANDS TO READ AND WRITE SENSOR BOARD IO 2016 Microchip Technology Inc. RN4870/71 PICtailTM/PICtail PLUS DAUGHTER BOARD USER'S GUIDE Chapter 4. RN4870 Sensor Board 4.1 OVERVIEW The RN4870 must be configured to enable the Sensor Board peripherals, and to enable the BLESensor App to communicate with the RN4870. The following is the configuration procedure: 1. Configure Peripheral IO port to sensors using command SW. 2. Define a GATT service (Sensor board) to hold the values from peripherals for a read access from a (GATT) client. 3. Similarly, when a GATT client writes a value to a GATT characteristic in a peripheral, there must be a method for the peripheral to write the value destined for characteristic into the peripheral port. 4. A GATT client on a Central (GAP) device is used to access the GATT characteristics in the peripheral which is an RN4870 with Sensor board. The GATT client for the Sensor board is an smartphone app named BLESensorApp. It is possible to use another RN4870 as the GATT client to access the RN4870 Sensor Board peripherals. The critical function of associating GATT characteristic with a peripheral is performed by the RN4870 scripting capability. The RN4870 can be configured manually by following the instructions in Section 4.2 through Section 4.5. Alternatively, the RN4870 can also be configured by using the PC Utility (RN4870_SensorBoard_Cfg_Cmd.exe) as described in Section 4.6 "Provision Utility". 4.2 CONFIGURING THE RN4870 MODULE SETTINGS The Sensor board can be configured by entering the following commands manually. Alternatively, the configuration commands are located in Appendix D. "Sensor Board Configuration Command Text". Each command can be copied to the clipboard via <CTRL+C> and sent to the RN4870 via TeraTerm using the <ALT+R> (Paste) command. 1.

Command GW is used to return to the current IO configuration. FIGURE 4-1: 4.3 RN4870 MODULE SETTINGS CONFIGURATION SENSOR BOARD GATT SERVICE The data from the RN4870 peripheral IO are stored in the characteristics of a custom GATT service accessed by the Sensor Board BLE Client App. To create the Sensor Board GATT Service, enter the following commands while in Command mode: 1. PS,AD11CF40063F11E5BE3E0002A5D5C51B to create a 128-bit UUID to identify the GATT Service. 2. PC,BF3FBD80063F11E59E690002A5D5C501,10,02 to declare a two-byte characteristic with notify property enabled. This characteristic stores the value of the ADC channel used for light sensor. 3. PC,BF3FBD80063F11E59E690002A5D5C502,10,02 to declare a two-byte characteristic with notify property enabled. This characteristic stores the value of ADC channel used for potentiometer. 4. PC,BF3FBD80063F11E59E690002A5D5C503,18,14 to declare a 20-byte value used to manage both the Push button state (virtual LED in App) and the LED blink rate on the Sensor board. Both notify and write properties are enabled for this characteristic. DS50002547A-page 30 2016 Microchip Technology Inc. 5. PC,BF3FBD80063F11E59E690002A5D5C504,10,02 to declare a two-byte characteristic with notify property enabled. This characteristic stores the value of the ADC channel used for the RN4870 internal temperature sensor. 6. PC,BF3FBD80063F11E59E690002A5D5C505,10,02 to declare a two-byte characteristic with notify property enabled. This characteristic stores the value of the ADC channel used for the RN4870 internal battery voltage sensor. 7. Command R,1 to reboot the RN4870 module 8. Command $$$ to enter Command mode 9. Command + to enable local echo 10. Command LS (list services) to display Sensor Board GATT Service as shown in Figure 4-2. FIGURE 4-2: SENSOR BOARD GATT SERVICE DECLARED IN RN4870 Figure 4-2 illustrates that a custom GATT service has been created in the RN4870 module. A 16-bit handle is assigned to each characteristic where each characteristic has a value in the handle and a property handle. The characteristic value and the properties are accessed by a short and more efficient 16-bit handle instead of the 128-bit UUID value. For example, two handles 0072 and 0073 are associated with the GATT characteristic BF3FBD80063F11E59E690002A5D5C501. A GATT client, such as a smartphone App, uses 0072 to read/write characteristic values, while 0073 is used to enable/disable the notify property. The next step is to transfer the sensor values from the peripheral IO into the GATT characteristics. This is done with the RN4870 scripting feature as described in Section 4.4 "Transferring Sensor Data into GATT Service Using Scripting". 2016 Microchip Technology Inc. DS50002547A-page 31 RN4870/71 PICtailTM/PICtail Plus Daughter Board User's Guide 4.4 TRANSFERRING SENSOR DATA INTO GATT SERVICE USING SCRIPTING For more information about the Sensor Board GATT service, refer to Section 4.3 "Sensor Board GATT Service". To populate the characteristics with data from the Sensor Board peripherals, and conversely transfer values received from the GAP client into peripheral IO channels, the RN4870/71 scripting feature is used. For more details on the scripting capabilities, refer to the " Bluetooth(R) Low Energy Module User's Guide" (DS50002466). The script that drives the peripheral values to and from the GATT service is written into the Non-Volatile Memory (NVM) of the RN4870/71 via the UART. First, put the module into Script Entry mode. The script is a series of text commands separated by carriage returns. The actual script is displayed in Section D.1.3 "Sensor Board Script". It can be copied to the clipboard and pasted in UART using TeraTerm. Similarly, the PC Utility can load it into RN4870. To load the Sensor board script manually, perform the following steps: 1. Connect the RN4870 PICtail to the host PC USB port a) Using Terminal Emulator, open the COM port to the RN4870 module b) Type $$$ to enter Command mode c) Enter + to turn on ECHO. 2. Enter Script Entry mode a) Enter command WW to put the RN4870 module into Script Entry mode. This command does not return an AOK response. b) Copy the script text from Section D.1.3 "Sensor Board Script" into the clipboard using <Ctrl+C>. c) Paste the script from TeraTerm using the <Alt+R> (Paste) command. A dialog window showing the script text from the clipboard is displayed as shown in Figure 4-3. FIGURE 4-3: SENSOR BOARD SCRIPT DISPLAYED FROM CLIPBOARD d) Press OK to load the script into the RN4870. e) After the script is pasted into the RN4870, exit Script Entry mode by pressing the <ESC> key. An AOK response is sent to the terminal. The script entry is shown in Figure 4-4. DS50002547A-page 32 2016 Microchip Technology Inc. FIGURE 4-4: f) Enter command R,1 to reboot the RN4870 module. After the reboot, the Sensor board is ready to use. The script event handlers can be seen on the TeraTerm display as shown in Figure 4-5. FIGURE 4-5: 2016 Microchip Technology Inc. COMPLETED SENSOR BOARD SCRIPT SENSOR SCRIPT RUNNING DS50002547A-page 33 RN4870/71 PICtailTM/PICtail Plus Daughter Board User's Guide 4.5 BLESENSORAPP SMARTPHONE APP The RN4870 Sensor board is a BLE Peripheral that advertises a GATT service to BLE Central devices. In this demonstration, the BLE Central device is a smartphone application named BLESensorApp. It is available for iOS and Android platforms via iTunes AppSTORE, and Google Play Store, respectively. Search for the "Microchip BLESensorApp", and download the App matching the icon in Figure 4-5. FIGURE 4-6: BLESENSORAPP ICON The BLESensorApp requires the Sensor board to be configured as described in Section 4.2-4.4. 1. Ensure that the Sensor board is attached to the RN4870 PICtail as shown in Figure 1-1. 2. Verify the jumpers and switches are positioned according to Figure 2-1 (SW7 must in be in position 1: Application mode. 3. Power the PICtail via USB a) Connect the RN4870 to power up. b) Verify that LED1 blinks blue with long interval. 4. Launch the BLESensorApp from the smartphone. In this example, the iOS version is used as shown in Figure 4-7. 5. The BLESensorApp attempts to connect to the first RN4870 Sensor board it discovers. Once connected, the main user interface of the BLESensorApp is displayed. DS50002547A-page 34 2016 Microchip Technology Inc. FIGURE 4-7: BLE DATA FLOW FROM SENSOR BOARD PERIPHERAL IO TO BLESENSORAPP Figure 4-7 illustrates the data flow from the RN4870 Sensor Peripheral IO to the smartphone app. The data streaming from the Sensor board to the App is performed by GATT Notifications. The script polls the sensor values, such as Switch, Light Meter, and writes the values into the appropriate GATT Characteristic. If the values change, a GATT Notification is sent to the BLESensorApp where the App updates the Graphical User Interface (GUI). BLE data can also be transferred from the BLESensorApp to the RN4870 module, and later processed by the script to write a received value into the Peripheral output channel. In the Sensor board demo, slider control is used on the App to select a blink rate value. The value is written to the GATT characteristic in the RN4870. The sensor script monitors the Characteristic for incoming data then extracts the value which is subsequently written to the Pulse-With Modulation (PWM) output peripheral to control LED blink rate. For more information on the BLE GATT data transfers, refer to Appendix C. "Bluetooth Low Energy Primer". 2016 Microchip Technology Inc. DS50002547A-page 35 RN4870/71 PICtailTM/PICtail Plus Daughter Board User's Guide 4.6 PROVISION UTILITY The RN4870/71 Provision Utility can be used to provision/configure the RN4870/71 Bluetooth Low Energy (BLE) module from a Windows Host PC using a wired connection over Universal Asynchronous Receiver/Transmitter (UART) interface. The RN4870/71 Provision Utility is used to program the RN4870/71 PICtail with the configuration and script to work with the Sensor board and the BLESensorAPP. The utility comes with a few prebuilt provision options that can be selected using the Provision File drop-down menu. Alternatively, a custom configuration XML file can be imported into the utility to provision the RN4870/71 module. Detailed instructions for provisioning the RN4870/71 module and creating custom configuration XML file are provided in the RN4870/71 Provision Utility Help files. Examples of the Provision XML file are in the Examples folder. Download the RN4870/71 Provision Utility from www.microchip.com/RN4870. Extract the contents into a separate folder on the host PC.

PIC Configuration Library 5.1 OVERVIEW The BM7x Configuration Library provides a set of functions for the RN4870/71 module to create command packets to perform the following functions: * * * * Update the Bluetooth parameter table Perform pairing procedure Configure a subset of parameters in Application mode Set the module into different operating modes The RN4870/71 module uses the UART interface for configuration and data transfer. The RN4870/71 Configuration and Events are defined as Command and Response protocol packets. A Command packet is sent to the RN4870/71 over UART to update a parameter. A Response packet is received from the RN4870/71 over UART for the command issued. RN4870/71 also sends out Event packets over UART when a defined event occurs. The PICtail Plus and PICtail interface on the RN4870/71 PICtail board are used to configure the RN4870/71 module over the UART using the BM7x Configuration Library with an external PIC MCU and to send and receive raw data over UART. The PICtail interface can also be used to access the UART and the GPIOs on the RN4870/71 module. 5.2 USING BM7X CONFIGURATION LIBRARY WITH PICtail BOARD The RN4870/71 PICtail plugs into the Explorer 16 Development board with a PIC32/PIC24 Plug-In-Module (PIM) or into the PIC18 Explorer board with a PIC18 PIM.

RN4870/71 PICtailTM/PICtail PLUS DAUGHTER BOARD USER'S GUIDE Appendix C. Bluetooth Low Energy Primer C.1 GAP ROLES: PERIPHERAL AND CENTRAL When two Bluetooth Low Energy (BLE) devices want to be connected, one device must be in Central role and the other in Peripheral role. The Peripheral device advertises to show its connectable status, while Central device scans service advertisements, and if needed, initiates a connection to the Peripheral device. Once connected, either end of the connection can choose to bond. Once bonded, all security related keys are saved and security process are waived when reconnecting. Bonded peripheral device can only perform direct advertise, therefore, unable to connect to a device other than its bonded peer. C.2 GATT SERVICE: CLIENT AND SERVER Similar to Bluetooth Classic, BLE uses the concept of profiles to ensure interoperability between different devices. As illustrated in Figure C-1, BLE profiles are collection of services. All BLE services are built on top of Generic Attribute Profile (GATT) where GATT defines accessibility of attributes called characteristics. The main functionality of the BLE profiles, therefore, is built around the characteristics. For those devices that maintain the value of characteristics in a service, such device is the Server of the service. On the other hand, devices that acquire data from their peer are called Client. Each service and its characteristics can be identified by their Universally Unique Identifier (UUID). The UUID can be a short form (16-bit) or long form (128-bit). As specified by Bluetooth Core Specifications, all Bluetooth SIG adopted (public) services and characteristics have short UUID (16-bit), while user defined private UUIDs are in long form (128-bit). For the details of Bluetooth SIG adopted services and characteristics, refer to https://developer.bluetooth.org/gatt/profiles/Pages/ProfilesHome.aspx. The accessibility of each characteristic is defined by a 8-bit characteristic property in bitmap format as shown in Table C-1. TABLE C-1: CHARACTERISTIC PROPERTIES Property Bitmap Value Description Extended Property(1) 0x80 Additional property available Authenticated Write(1) 0x40 Write characteristic with authentication from GATT client to GATT server Indicate 0x20 Indicate value of characteristic with acknowledgment from GATT server to GATT client Notify 0x10 Notify value of characteristic without acknowledgment from GATT server to GATT client Write 0x08 Write value of characteristic with acknowledgment from GATT client to GATT server Write without response 0x04 Write value of characteristic without acknowledgment from GATT client to GATT server Read 0x02 Read value of characteristic. Value is sent from GATT server to GATT client 0x01 Broadcast value of characteristic Broadcast(1) Note 1: 2016 Microchip Technology Inc. These features are supported in future firmware releases DS50002547A-page 53 RN4870/71 PICtailTM/PICtail Plus Daughter Board User's Guide As shown in Figure C-1, the GATT client can access the characteristics in the GATT server in the Peripheral device. When connected, the GATT client reads the GATT server service and characteristic UUIDs. The characteristic values can be accessed by the GATT client using Write, Read, Indication and Notifications. Write-REQ enables the GATT client to update characteristic values on the Peripheral's GATT server. The write requests can be performed using RN4870 CHW and CUW commands. Refer to Section 3.6 "Accessing GATT Service Using UART Commands and SmartDiscover App" for more information on GATT characteristic access commands. A Write-CMD message performs an unacknowledged write from a GATT client to the GATT server. This is allowed for Transparent UART Write procedure on the RN4870 when SR,0100 command is used. A GATT client sends Read-REQ read a characteristic value on the Peripheral's GATT server. The read requests can be performed using RN4870 CHR and CUR commands. Notifications and Indications are unsolicited updates sent from the GATT server to the GATT client. The GATT client must enable the Notification and Indication on a characteristic to receive the updates. On the RN487x module, this is done by using the CUW or CHW command to write non-zero value to the Notification Characteristic. When RN487x in Client mode receives a notification, the %WC,hhhh,ddddddd% message is returned on UART in Command mode.
