RadioLib SX126x LR-FHSS Modem Example
|
|
||||||
|
|
||||||
This example shows how to use LR-FHSS modem in SX126x chips.
|
|
||||||
This modem can only transmit data, and is not able to receive.
|
|
||||||
|
|
||||||
NOTE: The sketch below is just a guide on how to use
|
|
||||||
LR-FHSS modem, so this code should not be run directly!
|
|
||||||
Instead, modify the other examples to use LR-FHSS
|
|
||||||
modem and use the appropriate configuration
|
|
||||||
methods.
|
|
||||||
|
|
||||||

RadioLib SX126x LR-FHSS Modem Example
|
||||||
|
|
||||||
|
This example shows how to use LR-FHSS modem in SX126x chips.
|
||||||
|
This modem can only transmit data, and is not able to receive.
|
||||||
|
|
||||||
|
This example transmits packets using SX1262 LoRa radio module.
|
||||||
|
Each packet contains up to 256 bytes of data, in the form of:
|
||||||
|
- Arduino String
|
||||||
|
- null-terminated char array (C-string)
|
||||||
|
- arbitrary binary data (byte array)
|
||||||
|
|
||||||
|
Other modules from SX126x family can also be used.
|
||||||
|
|
||||||
|
Using blocking transmit is not recommended, as it will lead
|
||||||
|
to inefficient use of processor time!
|
||||||
|
Instead, interrupt transmit is recommended.
|
||||||
|
|
||||||
