RadioLib APRS Position Example
|
|
|
|
This example sends APRS position reports
|
|
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
|
|
|
|

|
|
