nimble stress test error (private notes for @geeksville)
findings:
only happens when stress testing multiple sleepwake cycles?
failed packets all have initial mbuflen of zero (should be 1)
restarting the connection on phone sometimes (but not always) fixes it (is the larger config nonce pushing packet size up too large?)
- packets >= 79 bytes (FromRadio) cause INVALID_OFFSET (7) gatt errors to be sent to the app
- some packets are missing
theory:
some sort of leak in mbuf storage during unfortunately timed sleep shutdowns
