I have set up a nano board with the DHT22 sensor and the wireless radio… Since the reside in the same room… I am hoping to be able load both the gateway and HumiditySensor.ino files on the board. I merged the code from both the provided .INO files but it doesn’t work…
can any tell me if I am even wasting my time:

- 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
*/
- ERR (red) - fast blink on error during transmission error or recieve crc error

The code loads onto the board without error… I had to comment out the the SENSOR gw(9,10) line as I didn’t know what to do there…
But the plugin doesn’t see the LIB version so I take it the code is wrong anyway…
