RadioLib CC1101 Receive Example (fixed length mode)
|
|
||||||
|
|
||||||
This example receives packets using CC1101 FSK radio module.
|
|
||||||
To successfully receive data, the following settings have to be the same
|
|
||||||
on both transmitter and receiver:
|
|
||||||
- carrier frequency
|
|
||||||
- bit rate
|
|
||||||
- frequency deviation
|
|
||||||
- sync word
|
|
||||||
|
|
||||||
