I'm trying to simulate "remote button" with two XBee modules. Button is connected to DIO1 (pin 19) on one XBee and volt-meter is connected to pin 19 of the other XBee. Xbee modules are XBP9B-DPST-001 (XBee-PRO 900HP).
XBee transmitter configuration:
atdh 13A200 <- address of the second XBee
atdl 40B47F46 <- address of the second XBee
atis <- button is released
atis <- button is pressed
atbc <-- counter is increasing
XBee receiver configuration:
atgd <- counter is increasing
I expect voltage on DIO1 to go high (2-3V) when the button is pressed. Unfortunately volt-meter is always showing 30mV on pin 19 (DIO1) of receiving XBee, regardless of the state of the button. Could you please suggest what could be a problem?
