XBee3 Wireless GPIO with Micro Development Board

XBee & XBee Gateway XBee - 802.15.4

I’m having some difficulty with a very basic GPIO problem using the XBee3 802.15.4 and the XBee Micro Development Board (xbib-c-mmt). I’ve been able to establish a network and send ASCII characters between my two modules. I am unable to turn on an LED from one board by triggering a GPIO on a second board.

My setup:
Device 1:
NI: Sender
PANID: 3001
CH: C
CE: End Device
MY: 1
DH: 0
DL: 2
AP: Transparent Mode
D0: Digital Input [3]
IR: 14 (20ms)
IC (Digital I/O Change Detection): 1
IA: FFFFFFFFFFFFFF
IU: Enabled

NI: Receiver
PANID: 3001
CH: C
CE: End Device
MY: 2
DH: 0
DL: 1
AP: Transparent Mode
P0: Digital Out, Low [4]. DIO10 is connected to a LED on the development board. If I set this to Digital Out, High [5] the LED will turn on. I want to turn the LED on from board 1.
IA: 1
IU: Enabled

It doesn’t make sense to me that I can pass ASCII characters between the chips but not I/O messages. I have tried doing DIO10 to DIO10 and that still doesn’t work. Am I missing something obvious? Is it possible to have DIO0 trigger DIO10?

Thanks,
Greg

Try setting IA to FFFF

No luck with FFFF. I think everything is connected correctly but I can’t get the diode to turn on.

I just noticed that you listed P0 as your output pin. That really need to be D0 on the output side instead of P0.

5

Is it possible to have D0 on one board control P0 of another board or does it have to be a 1 to 1? D0 only controls D0?

6

It needs to be one to one. IE D0 to D0.

Thanks to your help I was able to get DIO4 to change states based on a button input. I found a slightly concerning issue regarding the output. If I set DIO4 to Digital output, low [4] or Digital output, high [5] the output of the pin is 3.3V. When I push the button on the sender circuit it the output goes from 3.3V to 0V.

Any idea why I can’t get it to go from 0v to 3.3v?

Set the output to default out low.
