* First steps to unify GPS Lib for RAK 1910 and RAK 12500 * Technicalities. Out with the old and build the new. * Adapt Matrix * We use 0.4.5 now * While we're at it, yank the RAK815, it's EOL * Satisfy CI - for now * - yank UBX library, talk to GPS chip with NMEA only. - more autodetect going on, this time for the Eink Display. TODO: actually do something with the scan findings. * i swear this works on windows! :-) * these are only there to make CI happy * don't update eink display if not detected. * Replace Oberon Crypt Library with modified Adafruit Library. This elimintaes the need for the sdk-nfxlib submodule. * - Revert auto screen selection (incomplete) - Revert nrF crypto engine (needs more work) - add separate defines for not-auto-selecting screen lib. * Define 2 new variants for RAK - with or without epaper * Update variants Co-authored-by: Sacha Weatherstone <sachaw100@hotmail.com> Co-authored-by: Ben Meadors <thebentern@tuta.io>
