    In a project I am doing, I have to send analog readings of a soil moisture sensor through zigbee. I have connected the sensor Vcc to 5v and ground; the zigbee Vcc to 3.3v and ground. The analog pin of sensor to Txx pin of adapter on which the zigbee is mounter. On the coordinator zigbee, i/o packets are being recieved..but it is always giving value of "020a" or "020b" irrespective of the data from sensor. I have also fed the analog data of sensor through voltage divider to keep it within 1.2v range..can you suggest what I am doing wrong??

    Hi Kahoko, welcome to the forums.

    Your question is a little vague. Can you give more details o what specific parts you are using?

    And a schematic always helps too.

    The zigbee is mounted on a 5 pin adapter so I have connected the analog pin of sensor to tx pin of the adapter

    The adapter has only 5 pin: reset, tx, rx, gnd and vcc
