Where and how to flash the bms?Andrew0135 wrote: ↑Sat May 28, 2022 9:23 amAlways flashAquaman wrote: ↑Thu Jun 25, 2020 12:49 pmI have flashed BLE/DASH to 1.1.0_FULL
Could connect without IOT-BOX but it didn't recognize anything.
When connecting with IOT-box in parallel, it didn't recognize the model but told me:
Where did you connect TTL-serial, did you hook it up in parallel with IOT-BOX?
In what order do you flash, DRV(ESC) and BMS?
I just get connection timed out if I try to flash any of the DRV(ESC) fw, And write length out of range if I try to flash the BMS
Any tips, Please?
flash the BLE from 3 pin on the display dashboard with ST-Link
flash the BMS with CP2102
flash the ESC from Speed Control and ST-link

Pinout should be standard, starting from square pad, 3.3vcc, swim, GND, and reset. PRACTICE YOUR SOLDERING SKILLS. Use good solder and a good iron with a clean tip. It can be done,.I just knocked out two of em (snsc2.3 conversions). It's not perfect, there are kinks to work out, but you can and will get a rideable scooter if you are halfway intelligent, can parse the info that's here, or ask informed questions. I will help anyone who is actively trying, not just looking for soft food I had to chew.
