Bc127 firmware update cli

[ppaszkow]

Hi,
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

Bc127 manual firmware update #bc127

Hej I am looking for a way to update the bc127 manually via UART. My goal is to create a simple python script, which is doing that upgrade automatically. I did not found any documentation about the steps I need to take for a manual upgrade. The Melody manual tells only the command “DFU\r” but nothing more. It would be great to now the steps to do it without any tools. My steps so far: 1.) start BC127 2.) setup UART speed to 115200 3.) entering DFU mode 4.) sending dfu image Any ideas ho…

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

thanks

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.

Thanks,

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