Thanks for the information. Again, I was trying to find where the unknown AT Commands are coming; I tried to catch @ static void at_cmd_unknown(const char *command, void *user_data); But, no luck, no AT commands are caught there. If you can let me know, where all the AT commands will be handled would be of great help ( unknown - so that I can handle then) ManYThanks Prabhu On Mon, Jun 15, 2015 at 7:45 PM, Szymon Janc wrote: > Hi Prabhu, > > On Monday 15 of June 2015 19:11:32 Prabhu Chawandi wrote: >> Hi Szymon, >> >> Thanks for your reply.
