Hello, Im building a WSN for a domotic application, at this moment, im testing the Xbee ZB, im making a network with 1 coordinator and 2 end devices. My principal problem is that sometimes one of the ED doesnt TX the information to the coordinator and other times it does. All End Devices are connected to a pic microcontroler that indicates what is gonna be TX using the serial interface, and the Coordinator is pluuged to the PC using te XBEE Xplorer.
Another cuestion inside my apartment, the network doesnt form if the EDs are in another room (3 mtrs to the coordinator), only separated with the coordinator for 1 wall, according to the datashhet, the network should be form because for this devices the range is 40 mtrs indoor… anybody can explain this to me?
