Spinning on the responder can hang when the outgoing queue is full #85

Open jonas-schievink opened 4 years ago

jonas-schievink commented 4 years ago

The example uses code like this:

while resources.BLE_R.has_work() {
    resources.BLE_R.process_one().unwrap();
}

This code can spin forever when the queue of outgoing packets is full and doesn't get drained asynchronously.

Responder should probably get a method process_all() that takes this into account. We also have to ensure that the BLE worker gets rescheduled when a packet gets dequeued from the TX queue, not just when one gets enqueued into the RX queue.
