FTDI to flash LPS node firmware and to configure

The USB port on the LPS node came off. Is it possible to flash or configure the lps node using FTDI? If yes, how?

Yes it is possible but will require a bit of hacking. The ST UART bootloader is available on the FTDI debug port so by using this it should be possible to flash it. I have not tried this my self but don't see a reson why it shouldn't work. A quick search and I found
this video showing how someone did it on a similar STM32 device. To activate the bootloader hold the DFU button while powering the node (or resetting it).
Then to activate the FTDI debug port so you can use it to configure the node you need to build the firmware with the
makefile line
uncommented.

I did a quick test building the FW with the USE_FTDI_UART line and found out that it fails. If you would like to try this path a can try to fix it and push a version that works with the FTDI debug port?
