    Nanjing far driver controllers

    I have ND72530 controller, does anyone know anything about UART serial protocol used in this controller, I want to read UART data and convert to CANBUS messages.Listening on UART port with 19200bps connected PC I am receiving AT+PASS=35271949 message continuously.

    Changing ADC-General - Negative Ramping Time from 0.10s to 3s solve the regen problem now the regen is smooth.

    Hey, reverse direction is working using ADC settings DutyCycle Reverse Button and servo to GND, only one problem left, even the brake current and the regen current set to 0A at very low speed motor is trying to regen causing big vibration what might be the reason for this?

    Hi owhite, Vesc Tools Mobile apk is working I used the link https://forum.esk8.news/t/nrf51822-flashing-setup-in-windows-using-a-stlink-v2/30601 only work with nrf51822 BT module not working with HM-10 BT module and using this apk I saw max 55kmh , max mosfet temp 57C, my midmotor QS3000...

    Thank you owhite, slow start solved, my BMS max discharge current is 60A, can handle 80A for short time, two new BMS are comming 120A and 200A with relay, will try them also. now working on 1.Vesc Tool Android apk not connecting to BT module, did you use this apk? 2.Brake issue, VESC I think...

    I changed ADC Current Control to Duty Cycle and Switching Frequency back to 20Khz now it is ok but FETs are heating very fast,I have to install fans and make better cooling, motor is even not warm, QS3000 V3 is very good motor.

    Hi owhite, motor and battery current max are 193A,ADC Control Type is Current, my bike is 90kg quad bike and with my old 3kw bldc controller I have no slow start. What are your Switching Frequency, Dead Tiem Compansation parameters? My Motor and App configuration are attached.

    Hi Galp thank you for reply, could you share your motor and app configuration files. the problem is not to spin faster, it is spinning on flat road or with no load, but it has low torque startup, the motor is not rotating on first move. motor temperature - ok mosfet temperature - ok battery...

    I don't think that batteries are causing the problem, besc has very low starting torque,on flat road I can reach 50kmh and get 80A, same motor and same pack with my old 3kw chinese controller I have no problem, maybe some parameters on vesc tool are wrong, I'm using last firmware BESC_G2_FW...

    source code is attached written in STM32CubeIDE 1.4.2, OpenWrt is not finished yet, show only battery pack and part of motor data, when finished I can share them too.Kindle is only using Experimental Browser to display html pages from the router website.

    I was using previous FW BLDC_4_ChibiOS.bin and THR LED did light up, after loading lates FW BESC_G2_FW.bin did not, all other functions are ok.Does anybody know how to get Get_VESC_Data over CANBUS?

    The places of R66 and C66 at the github site are right but the labels on my pcb were switched and I switched them according to the labels which was wrong, so switching them again back solve the problem in FOC mode.Now everything is ok. I will follow galp instructions to solder bus bars with hot...

    Thank you for the thread owhite, I have also built BESC-G2 (FW http://pavlin.si/besc/wp-content/uploads/2020/08/BESC_G2_29.8.2020.zip) it is working in BLDC mode but not in FOC mode, trying to detect and get RL parameter the motor is not spinning at all , did you test in FOC mode?
