Overview

The BM-7x-OTA Dongle is a Bluetooth Low Energy (BLE) Dongle that communicates wirelessly with the BLE module on the end product's board to enable testing or programming Over The Air (OTA).  With RF transmit power -20dBm, the Dongle connects to the target board by a short distance preventing unnecessary connections to other boards nearby.  The default supported modules include BM70, RN4870, BM71, RN4871, BM77, RN4677, BM78 and RN4678.  With a micro-USB cable connected to a PC (Windows), a MPAF tool executes device testing or configures device parameters through Bluetooth BLE connection over the air.  On-board jumpers and status LEDs allow the user to quickly and easily test or program the target module.
