Hi everyone !
In my project , I want to get the RSS(Received Signal Strength) of Xbee frequently , so i choose to measuring the PWM output in pin 6 when received data package.
But i found a wired thing, that is ,when 2 Xbee(1 Coordinator and 1 Router) are putted into two 'far away' (more than 3 meter approximately) place, receiver Xbee(Router) can output PWM(indicates RSS) into it's pin 6 normally , but when they are putted together( distance less than 3 meter) , receiver Xbee can never output PWM in pin 6.
I was using Xbee Serial 2 Wire Antenna(ZB),2 Xbee are both downloaded AT firmware , their DH and DL are each others's SH and SL , communication between two device are work well.
so the problem seem that pin 6 of Xbee will output PWM only when they are putted 'far away' enough.
I was wondering it's that a normal phenomenal or something got wrong at my setting in Xbee command or something else.
I would appreciate any comment on my problem !
forgive my poor English , thank you !
