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);

there is something wrong… For me 87mA with screen and BLE com. !!! microcontrôleur ESP32-S 240 MHz Tensilica LX6

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

About Volts Variability… Last week I participated in a Mountain Bike race on difficult terrain On the bottom curve there is the recording of the battery SOC (550Wh) Yellow the decreasing Wh white the average of the volts blue the volts variability

@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,...

Yes but it's not the easiest way

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

Good ! now to improve your health and test the bike you are ready to do that :mrgreen: https://www.trans-portugal.com/mtb/en/

…and if the current measurement of the M500/600 is reliable the consumption measurement can be added to the DIY display or/and Garmin

75W, I chose the same value :mrgreen:

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)

You can alternate between data field every x seconds look at this:
