How to update firmware on the Flipsky 75100 & 75200 FOC ESC

Good news!!

NOTE: I share my Fiido Q1S micro motorcycle build log, including all the electronics and firmware, as OpenSource, here: Fiido Q1S 5kW dual motor: VESC + modular DIY OpenSource electronics and software | Endless Sphere DIY EV Forum

I flashed the firmware that improves the motor current on this cheap bad quality VESC and now the motor is much more silent, like a 100x improvement!!! The VESC motor auto-detection is almost perfect, but still seems the motor inductance value need to be corrected a bit - next I should do the hardware mod that should improve even more.

Finally I have a perfect silent motor, that I didn’t thought would be possible!!

Yesterday I did the usual 14 kms ride at the night to go to the gym and everything went well, except at very high currents - I may need to tweak a bit the detected motor L value.

And for the curious, I am using VESC on my EBikes / ESCooters / micro Emotorcycles and doing the high level logic, with DIY ESP32-S2/S3 boards, running high level Python firmware,to implement the system parts: main board (the communicates with VESC by UART), Display, BMS automatic turn on/off power board, rear lights board and front lights board. All this boards are simple DIY and communicate between them using wireless ESPnow.
