I am using digi xbee 3G Cellular module with xbee grove dev board. i have communicate the board with my server with the help of XCTU and it is working perfectly. Now i want to communicate with the server by AT command through Docklight or Hercules only as i don't want to open XCTU for the communication. how can i communicate with the server through docklight or hercules without open XCTU application ???
