RadioLib APRS Mic-E Example
This example sends APRS position reports
encoded in the Mic-E format using SX1278's
FSK modem. The data is modulated as AFSK
at 1200 baud using Bell 202 tones.
DO NOT transmit in APRS bands unless
you have a ham radio license!
Other modules that can be used for APRS:
- SX127x/RFM9x
- RF69
- SX1231
- CC1101
- nRF24
- Si443x/RFM2x
- SX126x/LLCC68 (only devices without TCXO!)
