There is a problem with the Bluetooth connection since the firmware update.


Hi, I am using CODE25.

I updated the firmware to V1.41 yesterday, but since the update, Bluetooth is no longer automatically connected.

There is no problem right after pairing Bluetooth according to the way suggested in troubleshooting.
However, after rebooting CODE25 not recognize the device again on the iPhone's Bluetooth settings.
So to use the Gateway app, I have to pair it with REV and Power each time
These problems have been seen since the firmware update and before that there was no problem at all.
I hope to know if there is a way to fix the Bluetooth connection problem or roll back to older firmware.

Did replacing the motherboard help?
I have the same problem - bluetooth has to be started manually every time.
