CA2RXU LoRa APRS Tracker/Station
This firmware is for using ESP32 based boards with LoRa Modules and GPS to live in the APRS world.
__(NOTE: To use Tx/Rx capabilities of this tracker you should have also an Tx/Rx LoRa iGate near you)__
You can support this project to continue to grow:
- Tracker with complete MENU !!! (see Wiki to know how to access it)
- Read, Write and Delete Messages (with I2C Keyboard or Phone).
- Asking Weather Report.
- Listening to other Trackers arround.
- Changing Display Eco Mode (turn off after 4 seg) and Screen Brightness.
- Processor from 240Mhz to 80MHz to save almost 20% power consumption.
- All GPS beacons/packet are encoded for less time on RF/LoRa Tx.
- Oled Screen shows Altitude+Speed+Course or BME280 Wx Data or Number of New Messages Received.
- Oled Screen shows Recent Heard Trackers/Station/iGates Tx.
- Bluetooth capabilities to connect (Android + APRSDroid) or (iPhone + APRS.fi app) and use it as TNC.
- Led Notifications for Tx and Messages Received.
- Sound Notifications with YL44 Buzzer Module.
- Wx data with BME280 Module showed on Screen and transmited as Wx Telemetry.
- Winlink Mails through APRSLink.
- Posibility to change between 3 mayor Frequencies used by LoRa APRS Worldwide.
