    Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

    I have a spare one still in the box which i can use for testing. At this moment somebody has my bike with him on a holiday. When it is back and still needed I can test it. Or can i also test the procedure without being connected to the tsdz2 motor by only power the sw102 lcd?

    I made a light icon in gimp and then tried to vectorize and scale (12x18) it with inkscape but no good results. Probably to small? I just upload it here so if somebody else want to try or use it for other displays. example: gimp file:

    Hello Casino, Good idea to make a drawing!! At this moment I only use the font from ugui in the sizes 22x36 (for assistlevel and speed) and the 6x8 (for time and BRK). The battery icon from Nick is 24x12.

    It was indeed a bad connection of one of the wires. Now everything is working!! :-) and got the example running. @Nick: We are missing the file nRF5_SDK_12.3.0\components\softdevice\s130\hex\s130_nrf51_2.0.1_softdevice.hex in the 12.3.0 branch can you add that to the branch? I had some...

    Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

    I did some researching on the internet and come to the same conclusion as Niek. For point A) not the problem of this project but of the shop selling those devices --> the best way would to explore the possibilities with Topologie. But as Nick mentioned I think they already explored this and made...

    Hello cnrd, I don't know where else to order this 1 to 4 female cable. In the past I ordered some cables from: https://www.e-bike-technologies.de/index.php/de/steckverbinder/steckverbinder-signal/steckverbinder-higo-z812-serie and soldered it together except the brakes but still have to do that...

    Maybe this questions is asked before but can't find it somewhere: Does the "chinese" sw102 (say around 50-60 dollar) also have the Nordic microcontroller with Bluetooth (nRF52)?

    Do you have a picture of how your lcd is connect to pins on the stlink clone? I couldn't find it on the wiki's. Do you let the lcd power from the "normal" connection or do you use the 3.3v on the printboard? Any tips on where to buy the sw102 lcd in Europe (if possible)? Thanks.

    Little question maybe it has been asked before but I can't find it. How does PAS max cadence exactly work? By default it is 110 but what if I put it on 90 or 125? I have a shimano nexus 8 gear and was playing around with it but I can not really feel a difference.

    I had some strange issues on firmware 13 so switched back to 12 but had also some strange things like motor power drops at higher speeds, offroad speed was ignored, wrong number of level assists etc. But today I reprogrammed again with firmware 12 with the sequence EndlessCadence mentioned above...

    I have exactly the same and sometimes on higher speed above 35km/u I get hick-ups with the power assist. It looks like it gets out of sync. I have the same configuration 36v motor and 48v batterypack. Just to be sure what values are you guys using for the parameters below using 0.12 version...

    I use it every day when I go into the city I go to 25km and 250 watt and switch when i go out of the city or where there is less traffic. I prefer the 2 buttons combination instead of 3 which will be hard to do while riding. If you disable offroad mode the power and up bottom is just working...

    I had the same issue for me it was the speedsensor just like eyebyesickle pointed out. In my case the magnet was also too close to the sensor.

    New "TSDZ2 Torque Sensor Central Motor"

    I just had my first test ride with the opensource firmware. Jiiihhaaa!! :D :D :D Way and way better than I expected. I wouldn't change a bit to improve driving experience. How it picks up the power support is really super. I also have a bosch motor and this comes pretty close. The info which...
