Feather 32u4 Bluefruit LE

Post by bonebrain »

I did an update to my Feather 32u4 Bluefruit LE via the app and appear to have bricked the bluetooth. I can not find the FW as it is not accessible from the device recovery page

I'm having a similar problem. I cannot get the app to talk to my feather 32u4. (do I need to get the nRF52840?). It seems to work perfect in the headphones video, he's even controlling the app with his iWatch.

Thanks

I tried but I don't think my IOS device is the problem. When I first powered up the feather it was working and the LED near the Bluetooth radio was flashing blue. I managed to connect to the device but it then indicated that there was a FW update. I selectecd one but since I did the update the LED that was flashing blue is now flashes red 3 times with no blue idicator at all.

I can connect to the device through the serial port and I am able to program the Arduino portion but the modem appears to be unresponsive.

I looked that the troubleshooting page and it talked about refalshing the device but the link to the firmware takes me nowhere

Are you referring to this page?
https://learn.adafruit.com/adafruit-fea ... e-recovery
or a page in the Bluefruit LE Connect app?

Try the recovery process and see if that brings it back:

Got it. The target name shifted to DFUtarg which threw me off. It appears to be working now

Thanks
