    Something is not right, start and end is the same after the second call, and elapsed is continuously increasing. Might be some watch / timeout stuck somewhere, the DHT22 library sets timeouts in multiple places...
    Try to run reset(1), remove power from the board, and run again with 10000 timeout.

    memory is ok. but rh and temp -1. why?..
