THIS MODULE MUST BE PLACED ABOVE ANY USB SERIAL CONSUMERS IN THE AIRFRAME!

Read USB serial for dfu command. Send '#
', 'bl
' to reset to DFU mode. The same command works with betaflight (tested with 4.1.1), allowing paparazzi to be uploaded directly to these boards.

The dfu command is automatically sent when uploading with DFU or DFU-UTIL (see configure below).

Add to your firmware section:

<module name="dfu_command"/>
