would like to understand what is happening, so any suggestions would be helpful.
I am using XBee Pro DM modules with 8067 firmware and API mode. When I send a broadcast message (using a Tx Request API frame) to 3 other DM modules, they respond ok and I can send many broadcast messages and they get communicated to the three other modules.
If I now power cycle one of the 3 modules and then again send a broadcast, only the power cycled module gets the broadcast message. If I power cycle another module, then it is the only one that receives a broadcast message. Other messages, like requesting the Rx level of any of the 3 modules, results in a valid response coming back. Also doing a node discovery results in all nodes coming up as being present.
I was needing a broadcast message to be received by all nodes at any time, which is not the case here. Has anybody got any suggestions as to what might be going on? Eventually I will want to broadcast to many more modules (next step is 20 odd modules) and if power cycling a module kills the broadcast to the other modules, its not going to work. Thanks.
