micropython/lora can not run the async example

[davefes]

Trying to run this example:
https://github.com/micropython/micropython-lib/tree/master/micropython/lora#asynchronous-api
The script will run once to the end of async def recv_coro(): and stop receiving. The async def send_coro(): just keeps running.

I was having similar trouble running a sync version and the only way I can keep that and the async version running is to do a machine.reset() at the end of the recv_coro().

Has anyone run that example successfully and hopefully be able suggest what basic step I have missed out.

Thanks

The code in recv_coro runs only once. There is no loop.

Change

async def recv_coro():
    rx = await modem.recv(2000)
    if rx:
        print(f'Received: {rx}')
    else:
        print('Timeout!')

to

async def recv_coro():
    while True:
        rx = await modem.recv(2000):
        if rx:
            print(f'Received: {rx}')
        else:
            print('Timeout!')

Thanks ... one of my first attempts at async ... I thought the async def init(): just kept them both running :(

Unfortunately, I was hoping for "reliable_delivery" and "power-backoff" but it seems this async example is more like a "simple_rxtx"
