Hi
Trying to update firmware on a Feather 32u4. I find the board in the app and all looks ok until I hit update. Then it starts the process, but soon tries to pair with the phone. I can’t skip the pairing question and if I pair, the process locks. Need to kill the app to get past that.
In order to find it in the app the board can’t be paired.
When using it for BT control of iPhone, iPad, Mac it only works with a fresh connection (forget device and pair again). It’s this issue I’m trying to solve with the firmware update.
Board got an old firmware from 2015. I think it was the second in the list.
Got 3.5.0 Bluefruit app.
Any thoughts?

Try clearing the cache to see if that helps:

and then try again.

Hi,
Thanks for the answer. But as stated in the first post, clearing cache/forget device is the only way of getting it to work. Once. Then I have to forget it again and start over.

hi the bluefruit maintainer is currently away for lunar new year... you could try posting a photo of what you see in the app update process, that could help debug

Re: Feather 32u4 Firmware update
Hi,
Tried to attach a video, not allowed.
If the device is paired, it shows up in the list of peripherals. Can be chosen, but can’t find any firmware update. Just stands in the search mode and waits.
So, to get further in the process:
Unpair.
Choose the device in the list.
Finds the list of firmware.
Choose the latest.
Hit OK.
Goes into enabling DFU-mode.
Shows Starting for half a second or so.
Then the question for pairing the device pops up.
If left in that state it just starts over and ends up with the same state. Continues to loop that.

Re: Feather 32u4 Firmware update
hi, I have tried to test with my iPhone but couldn't reproduce your issue.
Could you run
1. factory reset example here https://github.com/adafruit/Adafruit_Bl ... ctoryreset
2. Unpair all of Feather Bluefruit 32u4 from your ipad
3. Try again to see if it work out again.
During the DFU, it shouldn't execute a pairing request.

Re: Feather 32u4 Firmware update
Hi,
Sorry, no difference. Still tries to pair in the DFU-mode.
Found one more odd thing. I normally must forget the device twice. The first time nothing happens. Do it again, and it’s forgotten.
(Happens only with this Bluetooth device).

Re: Feather 32u4 Firmware update
I am out of idea, maybe you would consider to upgrade to our newer nRF52840 board which has more processing power and more features.
