Bluefruit UART stopped working after DFU update

[arlenn]

Hello,

With a new Bluefruit UART (BFU) the Bluefruit app for android prompted a firmware update. I set the DFU pin low and proceeded to perform the update. After reporting a successful update, the BFU will connect, but no longer transmits data. Sending data to the BFU though a terminal causes the DFU to disconnect.

I have updated the unit repeatedly using different firmware versions with files provided by the app as well as downloading directly from the adafruit github.

I am really at a loss at how to regain functionality of the device?

Bump.

Any of the Adafruit support staff have any insight on this?

Can you maybe try a factory reset? https://learn.adafruit.com/introducing- ... tory-reset

Also, if you have a USB Serial adapter cable, try connecting to let use know the results of an ATI command to check version numbers.
