I was able to reproduce this, thanks.
You're right, NSS must go low before checking BUSY pin. BUSY should be held high in sleep mode, and since we wait for BUSY to go low at the start of SX126x::SPItranscation()
, it will never leave the waiting loop, hence the timeout.
I'm not entirely sure why is NSS pulled low after checking BUSY pin - I think it might have been an effort to not start any SPI transactions as long as BUSY is high.
Will fix in a second.
