send_packet hangs after receive_packet

[smertrios]

Hi, I have a simple script which waits for a remote command then sends back some data:

PyLora.wait_for_packet(-1)
cmd = PyLora.receive_packet()
# process command:
...
# send response:
PyLora.send_packet(resp)

=> The last statement (send_packet) hangs, probably in the loop waiting for the IRQ_TX_DONE_MASK flag to clear.

note: if I comment out the call to receive_packet(), then send_packet() goes through just fine.

what am I missing?

I just fixed it by replacing the wait_for_packet() call with the "while not packet_available()"...

so I guess I don't understand what/how to use wait_for_packet.
