» Ag xtr 23: Send commands to weather station

Basic example that turns on and send commands to weather station. Please set DEBUG_XTR to 2 in order to print the answers by the serial monitor. This example permits to set Time and Date in Maximet RTC very easily via USB port. There is an interface which asks the user to introduce the Date and Time as specified without any need to change this code.

Required Materials

- 1 Waspmote Plug & Sense! Smart Agriculture Xtreme
- 1 Gill weather station

Notes

- This example is only valid for Waspmote v15

  SELECT THE RIGHT SOCKET FOR EACH SENSOR.

  Possible sockets for this sensor are:
  - XTR_SOCKET_E           _________
                          |---------|
                          | A  B  C |
                          |_D__E__F_|


  Example: a 5TM sensor on socket A will be
  [Sensor Class] [Sensor Name] [Selected socket]
  Decagon_5TM    mySensor      (XTR_SOCKET_A);

  Refer to the technical guide for information about possible combinations.
