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