Richonguzman / CD2RXU LoRa APRS Tracker/Station
(Firmware for Tx and Rx !!!)
NOTE: To take advantage of Tx/Rx capabilities you should have an Tx/R x LoRa iGate (near you) like:
https://github.com/richonguzman/LoRa_APRS_iGate
- NOW WE HAVE A MENU (just pushing the central button IO38)
- Saving, Reading and Deleting Messages.
- Asking Weather Report
- Listening to other Trackers arround.
- Changing Display Eco Mode (turn off after 4 seg).
- Processor from 240Mhz to 80MHz to save almost 20% power consumption (from ~ 100mA to almost ~80mA) (Thanks Mane76).
- All GPS beacons/packet are encoded for less time on RF/LoRa Tx.
- 4th line of the OLED SCREEN shows Altitude+Speed+Course or Number of New Messages Received.
