Hello, I have three Xbee Series 2, grove development boards. Node 1 is configured as an end device which has sensor data coming from an arduino board. Node 2 is a router which receives data from node 1, while node 3 is a coordinator which is connected to the PC, which communicates with the XCTU. I have configured PAN ID same for all three nodes. I made DH and DL of node 1 as SH and SL of node 2, and DH and DL of node 2 as SH and SL of node 3, while for coordinator I made DH and DL as 0. It is seen that sensor data is being received from node 1 to node 2, but from node 2, data is not communicated to node 3. No data is available in the XCTU terminal. While I tested for two nodes, it is working. When I introduced one more node (node 2) , data is not transferred to node 3. Kindly suggest what might be the issue. Thank you.
