Re: TSDZ2 EBike wireless standard (like Specialized Turbo Levo) - OpenSource

please try flashing the attached file.TSDZ2_wireless_ota_update.zip I've just flashed it... same issue :/ Do you have another phone or tablet you can try? I am wondering if there is a blue tooth issue with your phone. I followed the procedure in the video on three different phones: samsung s20+, mo...

Done, no devices on the bluetooth list.
And can you see the device on your Android Bluetooth list and on the Nordic app??

@casainho, Some time ago, you requested that I removed the flashing leds in the bootloader for dfu mode. Given the issues that a number of users have raised, maybe we need to re-instate the leds display during dfu to provide some visual assistance to the user. If we put it on the bootloader, then t...

Re: TSDZ2 EBike wireless standard (like Specialized Turbo Levo) - OpenSource

I would ask for waiting to the next stable release and then we can help to test again, as there are many changes on the LEDs and will be easy if we are all using the same firmware. If the TSDZ2 wireless board has the correct firmware flashed and is correctly powered up, then it must work always sho...

Re: TSDZ2 EBike wireless standard (like Specialized Turbo Levo) - OpenSource

Sorry, I misled you on the leds. We recently did a major led signalling update on the firmware which is planned for the next release. I forgot that this is not part of 0.6 2. If you see an led light up when you press reset it would seem you have power connected. No leds will light when you connect ...

Re: TSDZ2 EBike wireless standard (like Specialized Turbo Levo) - OpenSource

Since power is not an issue for the wireless controller board, maybe a 'breathing' blue led flash should be constantly on until a connection is made to the android app? This would certainly indicate that the board is active, and help to indicate connection. @beemac: what do you think? Since the TSD...

What type of plastic did you use for printing? Cheap PLA of black color.

Not so good print quality this time, thanks to the support configurations I did change: https://i...

What side of the handlebar do you have your buttons - left or right? Looks like right? I have my buttons on the left - wonder what others do?
You are lucky as that design is for left side. I use the main gears / rear gears on the right side and the remote on the left side.

How do you make the electrical connection to the button battery? I can see that it is very thin. In addition to brakes wire access, will there be enough room to tuck all the wires under the buttons once you solder the board? Can there be a removable access port on the bottom to allow for easier rep...

I am being learning FreeCAD to be able to design the remote - I am using as reference the design done by stancecoke . The idea of this design is to place the LED visible on top of the remote, so the NRF52 board is out on the top. I think there are 2 main issues with this design: 1. there is no space...

Re: New "TSDZ2 Torque Sensor Central Motor"

The later helical gears are much much quieter once they have worn in for a couple of hundred clicks and been regreased. Is the effort worth more than simply buying a later motor ? I have helical gears in all my EBike TSDZ2 motors and they clearly do an annoying audible noise that other good EBike m...

Re: Optimized TSDZ2 Firmware

Later I moved to a crude pll - estimating the error each time I detect a hall state change and subtracting this error (with a correction factor of about 0.2) from my pll increment. The result is no abrupt changes in angle, and a hugely reduced sensitivity to errors in hall sensor placement. Combine...
