This is a first version which has the following functionality:
- Logging GNSS nmea messgaes to lz4 compressed files on the featherwing sd card
- Daily uploading of gnsslog files to a webdav server share
- Led indicators showing status
- User button press rolls over the curren log and initiates an upload (otherwise this is done daily at midnight)
- The supplied binary firmware (mcuboot compatible) is compiled for the Actinius Icarus v1.4 target (NOT the newer v2 version yet)
