Hey guys!!!i have got 4 XBEE s2 modules.I have changed the parameters of XBEE using XCTU such that it read the analog voltage fron AD1 pin for every one second(it will be sleeping in rest of the time),and transmits the same to API coordinator XBEE.Both XBEEs are doing their jobs, and they are doing it fine.But when i try to upload new parameters in to XBEE using XCTU, a new window pops up saying "Unable to communicate with modem".i used libelium shield, Arduino 2560 to establish connection between XCTU,XBEE. [
Friends i have tried to troubleshoot it using a lot of methods, trust me i have been checking on net scinde seven days.I can't assume any hardware problem because the same problem repeated with 3 XBEEs.Now i have 3 XBEEs which doesn't work properly.
My boss wants some immediate results.Plz guys i need some real help here!!!!! [
thanks very much in advance.
