SX1262-Implement Retransmission Mechanism

[Nandhini-271]

I'm using the SX1262 LoRa module with an ESP32, programmed using the RadioLib library. This library has a built-in retransmission mechanism, where if the startTransmit or startReceive function fails, it automatically attempts retransmission. Could you please provide clarity on how this retransmission process works?

No, it does not. There's no such functionality directly in RadioLib. If you need it, you will have to either find a higher-layer protocol that does have it, or implement it yourself.

Which higher level protocol is used for retransmission?

LoRaWAN is a protocol that implements frame retransmission, but this is not implemented in the current release of RadioLib. I do have it implemented in a local copy that is likely to see the daylight through a PR in a week or maybe two. But whether you can use LoRaWAN highly depends on your situation, options & requirements.
