Re: Unable to exchange data if both router and coordinator are in API mode with Arduino

[Andrew Rapp]

I heard reports of others having problems with the S2B radios. I've never used them so can't comment on if there are compatibility issues. Try resetting to factory defaults and applying the minimal configuration per the wiki. You may want to try end device instead of router. Also make sure they are not in cyclic sleep mode if end device

I'm using two Arduino UNOs, two ZigBee Shields, xbee-arduino library version 0.3 with Arduino 1.0.1 and I'm trying to let my xbee modules (Series 2 PRO) communicate in API mode (with API mode = 2 in XCTU).

If I upload Rx sample for Series 2 to my first arduino with Xbee as Coordinator with API and then I uploaded Tx sample for Series 2 to my second arduino with Xbee as Router with API then router is able to connect to the coordinator, but no data is received correctly, in fact, I can't read any received packet.

On the contrary, if I configure the router as Router with AT mode, then, I'm able to receive packets with the Coordinator.

Why this happen? I'm not able to exchange data when I use both coordinator and router in API mode.

I need to be able to send and receive datas from my router nodes.
Is it possible to do this with xbee-arduino library?

Is there any sample where a router exchanges data with the coordinator?

Can you help me, please?

One problem I have had with the Series 1 XBee modules is that some versions of the firmware will allow you to send in API mode, but they don't allow receiving.

I have found that I need the latest firmware installed on all devices in the network for API mode to function correctly.

You may need to do something similar with your Series 2 XBee modules.

I've already installed the last firmware with xctu and it is 23A7 for the router API and 21A7 for coordinator API.
The problem is serious since I have to program 1000+ xbee modules and I'm not able to solve the problem.

Any suggestions?
