    Bafang M500/M600 thread

    Yes Wifi need more mA Use only for SetupRtcTime, OTA, …. ..and I turn off the wifi when I no longer need it After I use BLE only //========[C++ wifi stop]======= WiFi.disconnect(); WiFi.mode(WIFI_OFF);

    Bafang bbs01b 250w 36v or 48v?

    we compared to several owners of BBS01(b) according to our measurements bbs01(b) 36V and 48V it is the same motor (same rpm/V crankset = 2.35 without load) 2.35 x 42V = 98.7 rpm The difference is only the controller

    it is right and the lifespan will be better with a 5V-3.3V level shifter

    @Casainho now that you are equipped :thumb: You can try to make custom fields This is how the Garmin calculates custom fields

    the BBS is for the KIT market with fewer regulatory constraints For other motors intended mainly for complete bikes, the regulations require that they cannot be easily modified. You can't easily modify Bosch, Brose, Yamaha,...

    This is exactly what I do with the uart version Doing the same thing with the can protocol is no problem Casainho will be able to easily do it The difficulty for many people is more on the NRF52840 which is less popular for beginners An ESP32 version would have been much easier for the walk...

    @casainho to lower the level without touching the firmware On the BBS01 I use the PWM method: if you have a level 0 (no motor) you can try to do quickly alternate level 1 and 0 to have an intermediate level 250mS between each level send Given the progressiveness the engine firmware averages

    What is the minimum intensity at level 1 on M500/M600? the level should not be lowered too much because the efficiency drops at low level Below is a BBS01 wheel in the air measurement to see the power needed to overcome friction (chain + motor) -> loss about 12W (0.3A at 42V)

    Very Good work Casainho ! :thumb: the walk rpm seems low (without throttle) You don't have to go through the original CAN for walk mode You must use a gpio DAC with PID calculation to have 6 km/h max (the motor speed which adapts according of rear gear) This is a very important function...

    for curiosity I test the NRF52840 My first impression it is less easy and slower to develop than ARDUINO ESP32 (BLE + WIFI) The NRF only benefit is ANT+ If I need ANT+ I'm thinking of using the NRF only as ANT+ transmitter The ARDUINO ESP32 community is bigger for help CAN Protocol ESP32 –>...
