First XBee Test

From Robert Faludi Building Wireless Sensor Networks book chapter III Build a Better Doorbell page 57

• One node configured as Coordinator AT and the other as Router AT using X-CTU utility
• Both nodes configured from serial terminal 9600 8N1
• DH,DL is the address of the opposite node. This address is printed on the module

• +++ changed the mode from transparent to AT commands. This lasts for 10 seconds
• PANID Address is set to 2011
• Destination Address High and Low as printed to opposite module
• Write parameters to EEPROM

• Lines 19,20 of BUTTON Arduino sketch transmits character D every 10 seconds
• Receiver Acknowledges transmitting ACK
  

So

• The Green-Led (RSSI)on both nodes blinks every 10 seconds
• Checking the Green Led we were able to test the RF range of the nodes
• Checking the intensity of the RSSI Green Led we have an indication of the RF link level

• The measured range is: 30 steps Indoors Line Of Sight
