Is there any possibility that MP could output certain data - for example: GPS position, Altitude, Battery volts, current, MODE -
to another device through a USB/serial connection? A simple comma delimited format with a “SYNC” byte at the start (0xFE,0xFE for example) would be fine. The user would be responsible for parsing. A simple bit mask would determine which items were sent. Nothing fancy.
MP has all those parameters decoded, and it would sometimes be nice to “grab” them for various uses by an external device.
