Trigger TX on GPIO

Hi,

I know that this is possible, but I do not remember how to trigger a TX on LoRa transceiver with a signal on DIO, rather than with the high latency SPI transfert.
Can I have some support on this feature ?

Thanks.

Hello @nop.microwave - welcome on the developer portal!

On the existing transceivers, it is not possible to trig a Tx with a GPIO. There are some features like “Rx then Tx” (also called LBT - Listen Before Talk) where a transmission is initiated if the RF channel is free.
