I am new in the Xbee world, I have 4 Xbee S1 802.15.4, that 3 are end device and one a coordinator.
The end devices transmit good to coordinator.The coordinator is connect to Raspberry Pi via USB with a Xbee USB Explorer. The communication is through serial and can see the data for the end devices, use python.
How can send a signal from the coordinator to each end device for wait to start the transmission?
In this moment I have the configuration in API Mode.
