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

[rananna]

Could be an issue realated to a bootloader flashing error?

@rananna, maybe you can send another version with an increased APP_VER_MAJOR = 0 and APP_VER_MINOR = 6?

I can only say that the latest firmware updates well for me using the bootloader.

here is the file that @casainho recommends:
View attachment TSDZ2_wireless_ota_update.zip

 

[rananna]

To be as clear as possible, this is the complete procedure i have followed:
1- Flashed bootloader (**Verified OK**)
1- Wired all the board and motor and double checked
2- Flashed motor firmware v1.1.1 (hex file)
3- Entered in DFU mode (power on from battery switch -> very long press of white big button on nrf52840)
4- Opened Nrf Connect, scan for devices, connect to TSDZ2_DFU
5- Uploaded the distribution packet you uploaded here (.zip)
6- Upload done, disconnecting
7- Pushing the reset button (the small, side one) only green led blinks
8- I cannot see any bluetooth device in:
-Ebike v0.31 Android app
-Smartphone bluetooth device list
-PC bluetooth device list
9- moreover: the devices is not bonded with my devices, i've tried with 3 different smartphones, i'm testing also another board (this one is not wired) with the same results.

Thank you

Everything you write looks ok.
However, the firmware is clearly not updating.
With the new firmware I sent you installed, you should definitely see red yellow and green leds light up when you reset the board using the small button( not the white button)
If you can, please record a video of the nrf connect app performing the update.
You should see a graph populate from left to right and when it completes do any messages display on the app?
Thanks for helping us track down the issue.

We do not have too many things left to check.
one is a faulty board.
However, since this is happening to two boards it seems unlikely that BOTH boards are faulty.
The other thing that can affect flashing is the power supply going to the board.
Are you powering with 3.3V or 5V?
Can you try another power supply?
what board pin is the voltage connected to?

Your video looks fine.
I just repeated all the steps myself with my board.
At the end of the flash( when the graph is all the way to the right) the red, yellow and green leds light once in succession ( no need to press reset)
I presume you do not see this?

You are right, i see nothing

Power supply or maybe a faulty bootloader flash.
Can you try another power supply?

The wired board is powered by 5v dd7818ta (checked with multimeter).
The not wired one is powered by a bench psu to vbus e gnd at 3.3v

@casainho,
Please check the issues list on github

Something strange happened: after i flashed your latest file.zip i've flashed alsi the bootloader.zip via nrf app... The red led starts blinking, but still not appearing on bluetooth device list.

So i've tried to reflash the file.zip v0.62... no leds blinking, no device on the list

OK, just to see if it is related to the wireless controller files, please flash this wireless remote file and tell me if after flashing you see the red, yellow and green leds light up, followed by a red flashing led.
You will not see anything in bluetooth for the wireless remote.

It is possible that this could explain the issues you are having with flashing.
