CC2531 red LED?


I have been trying to solve problems with my CC2531 / Zigbee2mqtt setup and decided to try a different channel in the Zigbee2mqtt config in an attempt to see if that would help with being able to pair devices.

Since changing the channel my CC2531 adapter now shows both red and green LEDs when first connected and then after a minute the LED goes red and nothing works. The USB device is recognise but that is about as far as it gets.

Unfortunately I purchased the CC2531 pre-flashed so I do not have the equipment to re-flash it, is there a way to reset it?
