I was having some problems with my sck 2.3 where it was locking up at 3am each morning and needed a complete power dis-connect and re-connect to get it going again. I though I would install the latest firmware. The file is SAM_firmware_sck2.uf2. This has fixed the 3am restart but the kit now says it is sck2.1 and none of the sensors work anymore. As far as I can see the only returned values are for the battery and Wifi strength.
The kit ID is 18375
Is this the correct firmware or should I be using something else?
