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 connec-
tion over Universal Asynchronous Receiver/Transmitter (UART) interface. The
RN4870/71 Provision Utility is used to program the RN4870/71 PICtail with the config-
uration 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 con-
figuration 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. The contents of the extracted folder
include the RN4870/71 Provision Utility executable, the RN4870/71 Provision Utility
Help files and the example configuration XML files. This utility requires the MCP2200
USB/UART CDC drivers. The driver is also available from the web page. Install the
driver if needed.
To configure an RN4870 PICtail with a Sensor board plugged in, perform the following
steps:
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. Connect the RN4870 to the host PC using the micro USB cable and verify that
LED1 blinks blue with long interval.
4. Wait for the RN4870 board to successfully enumerate as a Serial Port device.
5. After the RN4870 board enumerates as a Serial Port device, open the Device
Manager on the Windows PC and note down the COM port number assigned to
the RN4870 board under 'Ports'.
6. Run the RN4870 Provision Utility (RN4870ProvisionUtility.exe) on the Windows
PC. Refer to Figure 4-8 .

Note: While the provisioning is in progress, the RN4870/71 must not be discon-
nected and the process is uninterrupted. If the provisioning process is inter-
rupted, the RN4870/71 module may
not be configured as desired.
