Bc127 firmware update cli

I would like to update the BC127 FW using a command line interface (CLI) using serial interface.
The Melody DFU exe is nice, but I would like something that can be automated.

I tried this procedure or script provided by this user but it doesn’t work

can you please provide the correct procedure or ideally a script that can update BC127 FW?


Hi ppaszkow,

Sierra provides the way to upgrade firmware over UART interface by using their official upgrade tool. They don’t provide any automatic process for upgrading FW on this product.


Can you provide the procedure/protocol used so that I can try to implement myself?
