Serial flush in sleep method also means one less code in examples. Removed set(bool) in message. Not needed. getBool just calls getInt __attribute__((packed)) for RPI compability Print more info in send/read debug prints. Get internalTemp returns full degrees and uses longer Vref delay Fix debug print gateway prepend (wrong command/type) Fixed problem in RelayWithButton example. Now working with ack in both directions. Serial protocol changed (incoming serial message have an new ack-parameter)
