Lora JOIN request fails & RX TIMEOUT

[stevencellist]

The main thing that I observe is this: note the time difference between the Rx1 window opening and the IRQ received.

Successful join:

In case of the failed join, there is only a 20ms Rx1 window apparently! That is quite a stretch… I’m not completely up to date on the conditions to stay in Rx mode for the LR11xx series, but 20ms is really optimistic as far as I’m concerned.
