RadioLib Pager (POCSAG) Receive Example
|
|
|
|
This example shows how to receive FSK packets without using
|
|
SX127x packet engine.
|
|
|
|
This example receives POCSAG messages using SX1278's
|
|
FSK modem in direct mode.
|
|
|
|
Other modules that can be used to receive POCSAG:
|
|
- SX127x/RFM9x
|
|
- RF69
|
|
- SX1231
|
|
- CC1101
|
|
- Si443x/RFM2x
|
|
|
|
For default module settings, see the wiki page
|
