Joining an existing network process requires some information about the network to join. In LoRa mode, two parameters are needed: channel and mode.

Encryption is optional.

Channel

To set channel, use the API function responsible for that matter.

Example of use:

{
    sx1272.setChannel(CH_04_900); // Set channel number 4 in 900 band
}

SX1272 configuration example:

Mode

To set mode, use the API function responsible for that matter.

Example of use:

{
    sx1272.setMode(3); // Set LoRa mode number 3
}

SX1272 configuration example:
