Unfortunately, I wasn't able to flash the BLE onto the cloned purple dash. This was somewhat expected. Just wondering how I can go about flashing the BMS on the external ...

I bought 3 of these. 2 of them have oem green boards, 1 has a purple clone. I was able to flash the 2 boards via ST-Link successfully which unlocked bluetooth flashing capability and speed to 20mph among other things.
