3.3 Device Programming

The RNBD350 device is available for purchase with a pre-programmed firmware. Microchip periodically releases the firmware for fixing previously-reported issues or to implement the latest feature support. There are two ways to perform a regular firmware update:
  1. Serial DFU command-based update over UART
  2. Advanced programming
For an advanced programming option (SWD), go to support.microchip.com.
Note: For the serial DFU and OTA programming guidance, refer to the RNBD350 Bluetooth® Low Energy Module User’s Guide (DS50003684).
