Firmware Update Problem RN-52 Bluetooth Audio Module

Wireless & IoT Bluetooth
1

Hello,

I updated the firmware of my RN-52 Bluetooth Audio Module to RN52SRC firmware. After I tried to change the firmware back to the original firmware (which I saved during the first firmware update process) DFU Utility reported an error after the upload process when trying to restart the device. Now I cannot access the module neither via USB nor via UART.

Any chance to get the module back running.

Kind Regards

Thomas

Hi Thomas.

Unless you can get access to whatever device programmer the original manufacturer uses to do the initial firmware loading, you’re probably not going to be able to recover the module. :frowning:
