I just bough 3 XBee PRO S2B and update the firmware of all of them, one as Coordinator AT and the other two as End Devices AT.
I just config the Coordinator to send a broadcast signal in transparent mode, in that way the end devices could read the data and send to a microcontroller that use relays to turn on/off a bunch of big light in a company client of mine.
The problem is that time by time, the connection is broken and one of the end devices is not able to receive the serial data, I have to unplug the power supply and reconnect over 10 minutes later to get the communication working again, to have the same problem later.
I just change the packetization timeout to 0, and nothing else in the end devices from the default configuration, because if I where using broadcast signals, there where be no problem with addresing, plus the end devices don´t have to talk with the coordinator.
I have checked the parameters by default, and I don´t see any problem with the sleeping time, etc etc... I have no idea what to do and I have to finish that job asap.
Thanks in advance,
