#GSMAD

1. Hi,

   I have a simple question:

    

   by sending the command:

    

   at#gsmad=3

   #GSMAD: 1

   OK

    

   the response is ever  #GSMAD: 1 (antenna connector short circuited to ground)

   even if the antenna is properly connected, or if it is disconnected !!

    

   why ?

   How do I detect the correct connection of the antenna?

   1. Does your module register in a network? What is the answer of AT#MONI?

         Hi, thank you for reply,

          

          Here are the commands sent:

          

         AT#MONI

          

         #MONI: I WIND BSIC:72 RxQual:0 LAC:7D16 Id:3C03 ARFCN:748 PWR:-79dbm TA:1

         OK
         at#gsmad=3

         #GSMAD: 1 (antenna connector short circuited to ground) it’s not true !!!

         OK

          

         at#gsmad?

         #GSMAD: 0,0,120,8,0

         OK

          

         I’m waiting for new…

         1. Did you implement the antenna detection circuit as described in the Application Note?

            1. Wow,

                

               I did not understand that it requires additional circuitry…

                

               I had not read this document…

               but on the AT_Commands_Reference_Guide (#GSMAD) is not clearly explained …!

                

               thanks anyway
