Week 3 (20th Feb 2015)
This is the third week of our weather station project. Continuing with the task completed during the last two weeks, this week we focused on realizing XBee connection between two microcontrollers.
By following the steps listed in the reference book, one of the XBee has been configured as ZIGBEE COORDINATOR AT and the other as ZIGBEE ROUTER AT through the software of X-CTU.
Having tested with the AT commands in Tera Term, both coordinator radio and router radio have been set and checked successfully.

Then the most important feature that we have already realized is the chat between two XBees. It shows that the text which is typed in the serial terminal program on the first Tera Term display window will appear on the serial terminal screen of the second radio.

During this process, we have met several troubles. One XBee on the FRDM-KL46Z did not work for many times. Thanks to the trouble shooting steps and multiple times of tries, we have finally debugged the function and completed the task left for two weeks.
The following tasks include:
First, the signal types of the wind speed, wind direction, rainfall and temperature should be specified.
Second, the most significant task is programming.
