SX1280 startTransmit after CAD not working about radiolib HOT 4 CLOSED

By implication CAD is doing a receive - in this case listening across spreading factors. So the radio isn't really setup for a transmit on a particularly SF. Maybe set the SF you want to use before transmitting?

@jonas-koeritz The fact that SX128x lacks the interface for interrupt-driven CAD is an oversight on my part and will be rectified - thanks! However, I was unable to replicate the primary issue which is that startTransmit after CAD does not send a packet. Could you please fill in the infromation requested by the issue template, mainly the code you are running?

Thanks for getting back on the interrupt driven CAD stuff. I fixed my other issue in the meantime. It was caused by an integration error, while debugging I had to detach a component, which caused the main loop to run slowly (waiting for that component to respond). As a result, the interrupt flags where not checked/cleared correctly.

@jonas-koeritz glad I could help! Do let me know if you get a chance to try the interrupt-driven version of CAD (I only found one SX1280 device so I couldn't test it fully).
