3.4 Device Programming

The RNBD451 device is available for purchase with a pre-programmed firmware. Microchip periodically releases the firmware for fixing previously reported issues or to implement latest feature support. There are two ways to perform regular firmware update:
  1. Serial DFU command based update over UART
  2. Over-the-air (OTA) update of firmware using Microchip Bluetooth Data (MBD) mobile application or module to module OTA update (OTAPC mode commands)
  3. Advanced programming
For advanced programming option (SWD), go to support.microchip.com.
Note: For the serial DFU and OTA programming guidance, refer to the RNBD451 Bluetooth Low Energy Module User’s Guide (DS50003467).
