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)

|
* DESCRIPTION
|
|
* The ArduinoGateway prints data received from sensors on the serial link.
|
|
* The gateway accepts input on seral which will be sent out on radio network.
|
|
*
|
|
* The GW code is designed for Arduino Nano 328p / 16MHz
|
|
*
|
|
* Wire connections (OPTIONAL):
|
|
* - Inclusion button should be connected between digital pin 3 and GND
|
|
* - RX/TX/ERR leds need to be connected between +5V (anode) and digital ping 6/5/4 with resistor 270-330R in a series
|
|
*
|
|
* LED purposes:
|
|
* - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
|
|
* - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
|
|
* - ERR (red) - fast blink on error during transmission error or recieve crc error
