I have configured a network with xbee pro 900hp modules.
One of them is the coordinator (API=1); others are Routers. (API=1)
When I send a Transmission Request (0x10) from Coordinator to any router device, I can see the response from the router (0x8B) and successful. (no errors). The problem is: there isn't UART output.
When I send a Transmission request from the Router to Coordinator, all is OK, and I see the Cordinator response frame as UART output .
