Bootloader does not flash the firmware correctly anymore

[ataffanel]

Flashing the firmware over Bluetooth does not seems to work anymore. As describes in bitcraze/discussions#632, it ends up with an error and left the STM32 in a non-working state.

It is still possible to start the bootloader by pressing the power button until the blue led blinks, but flashing again will give the same error.

The reason for this failure needs to be investigated.

This seems to be the same issue, that i was posting recently. Maybe a downgrade on the firmware could help.
I could implement an option to select a firmware version.
@ataffanel could you point me to a link, on where i can download a specific firmware?

E.g. https://api.github.com/repos/bitcraze/crazyflie-release/releases/2025.02

I unfortunately do not know what firmware might work. For sure, firmware after the bluetooth stack update will have a problem, so 2023.11 is the latest firmware I would expect to work with the current android client.

Ok, will try it out tonight. Is there an option to get the zip file via the github api?
Because I know, how to get the latest firmware, but not specific ones.
And is there also an option to read the version of the crazyflie? Otherwise the users will have to know, which version of the flight controller they have bought and select the version specifically. Otherwise i could recommend a version within the app.

This is actually done in the Android firmware and in the Python client, so yes, there is an API that can list all releases from a project in Github. This is the URI that is used for that in the client: https://github.com/bitcraze/crazyflie-clients-python/blob/d17a664c9ae55ea70cb9a2df88ac912364bfb1a5/src/cfclient/ui/dialogs/bootloader.py#L61-L63
