Hi, everyone.
I have been using Xbee S2 for point-to-point RF communication.
Now I need to compose mesh network with 3 XBee modules.
I have seen that it is possible with XBee Pro DM 3B programmable and already purchased 3 modules.
(http://www.digi.com/products/models/xbp9b-dmstb002)
My purpose is this:
(Slave) <--- ---> Master <--- ---> (Slave)
Master should communicate with 2 slaves.
Each Slave can only communicate with Master.
To implement this idea, I set Network ID of all 3 modules as same value.
And set CE of master as "Indirect Msg Coordinator" in XCTU, set CE of slave as "Non-Routing Module".
But I could not send Tx frame as indicated in http://www.digi.com/resources/documentation/Digidocs/90002127/tasks/t_send_an_api_frame_from_the_third_xbee_module_to_other_modules.htm
It says "Connection with the device is closed."
I am wondering if anyone would teach me how to configure each modules.
And it'd be very appreciated if you could inform me about python API of these modules.
Best regards.
