Here you will find how i have calculated the reference angle between rotor and applied phase current under "no load condition". Optimized TSDZ2 Firmware As you know, then the reference (no-load) angle should be corrected according to motor phase current and motor speed, but i have not found any...

If you want to measure the current using an Hall effect sensor you should pay attention to the reaction time of the sensor compared to the PWM frequency you want to use.

If you have the same problem with the OEM firmware and without the ESP32 board, maybe the problem is the Display or the wiring between motor and Display. If I remember correctly, E03 means that the display is not receiving any data.

No, it is just an alternative to the offset calculation which is done automatically when the motor is turned on.

If checked you shoud enter the ADC value you have without any pressure on pedals. In you case is 194, and so a value around 198 would be ok.

No fill is also OK.

For high cadence, in my opinion, the best solution is a 36v motor with 48v battery. In this configuration the motor will be able to provide high power even at high cadence with better efficiency than a motor with a standard battery of the same voltage using field weakening. This firmware uses...

In the last Android apk the OTA update is broken. Revert to 2.1.12 version to do the OTA update, then you can return to the last version (2.2.0). I have already a new Android version with the bug fixed and i will publish the new apk on the github project page About the speed problem, probably...

It is available the Cycling Power Service (UUID 0x1818)

New version of the Android app. It is just a Technology refresh. - Removed various deprecated classes - Compiled with the last Android SDK 33 (Android 13) - New Bluetooth permissions (if running on Android 12 and up) TSDZ2_ESP32v2.2.0.apk

It can't work if you use a firmware other than the one provided by the project.

If you want to turn on the system with a bluetooth connection, the ESP32 cannot stay in sleep mode since the radio interface must be active. Yes the switch should be between +Batt and +LCD and should manage the battery voltage and at most 100/200 mA.

no, there is no switch. For your scenario you would need a small external switch to turn on the ESP32 board and bike controller. The ESP32 board will also consume power otherwise. (ESP32 consumes more current than the controller STM8 MCU) So you should also modify the ESP32 firmware and also the...

Everything seems ok to me

the error is self explanatory. Check the electrical connection of the rxc, txc signals.
