RadioLib LR11x0 Blocking Channel Activity Detection Example
|
|
|
|
This example uses LR1110 to scan the current LoRa
|
|
channel and detect ongoing LoRa transmissions.
|
|
Unlike SX127x CAD, LR11x0 can detect any part
|
|
of LoRa transmission, not just the preamble.
|
|
|
|
Other modules from LR11x0 family can also be used.
|
|
|
|
Using blocking CAD is not recommended, as it will lead
|
|
to significant amount of timeouts, inefficient use of processor
|
|
time and can some miss packets!
|
|
Instead, interrupt CAD is recommended.
|
|
|
|
