Topic: three XBees line passing problem (Read 526 times) previous topic - next topic



I need to use three XBees in the line passing mode. Two XBees are attached to different sensors serving as transmitters and one XBee serves as a receiver to trigger a motor based on the condition of the two sensors attached to the transmitting XBees. For now, I tried just to attache a force sensor that produces 0V when not pushed and 3 V when pushed to one of the transmitting XBees (the sensor is attached to pin AD4/DIO4). I left the 2nd transmitting XBee free not attached to anything.

I have the connection right and there is an association between the transmitters and receiver. They are connected fine.

The problem is that when I am measuring the voltage on the AD4/DIO4 pin of the receiver, I see the voltage fluctuating between 0 and 3 constantly when I do not push on the force sensor. When I push on the force sensor, the voltage on the AD4/DIO4 pin of the receiver changes to 3 volts for sometime and again the voltage starts to fluctuate.

How can I configure these two transmitting XBees and one receiving XBee to get stable sensor status from each transmitting XBee?

XBees configuration parameters:

            Receiver      Transmitters
ATID       1234        1234
ATMY       5678        1234
ATDL       1234        5678
ATAI        0                0
ATIR        14        -
ATIT        5                -
ATBD      3                3
ATIU        1                -
ATIA        -                5678
ATD0        3                4
ATD1        3                4
ATD2        3                4
ATD3        3                4
ATD4        3                4
ATD6        3                4

Thank you very much in advance for your feedback and assistance.
