before upgrading my m365 classic, i first upgraded its driver to 1.5.5 using mi.cfw.sh generator like an m365 pro. Then connected the purple board and it worked. But i had some stuttering problems in D and S mode
The board itself let me change/upgrade bms or driver using downg app but it was not possible to update BLE (it seems like it is working but it is not changing). These lilac/purple boards have a different architecture (tm1637 chip, legs different etc) then m365 pro original/clone boards.
By default ble version shows as 910. You could change the BLE to 090 with st-link using correct hex file which you can find here

pin connections are at the back. The order is:
3.3v - SWDIO- SWDCLK - GND
After upgrading ble to 090 all my problems gone.
You can not use camialfa v74 BLE files etc. since architecture is different.
BMS 126 (7800mah) you can find here:
