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 how to solve that problem?
