Do the OEM green vs purple clone have any difference in Bluetooth behavior? Ie does bluetooth connect out of the box on one and not the other?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. I tried flashing the clone but bricked it and can't find the original firmware for it yet to reflash. I'll probably end up buying an oem.
You just need an $8 st-link v2 usb adapter from amazon and some basic soldering skills.
Trying to figure if there's a way to know what dash we have before we even disassemble the scooter
