In GL865 QUAD voice call, ATD calling a mobile number,connected…. after that the call disconnected by the mobile gives me a NO CARRIER in AT terminal software and the call terminated in the module side.
But, when i do the same for a Landline phone, i did not get a NO CARRIER or the call is not terminated.
What could be the reason ?
How can we find weather the call is disconnected or the put off the receiver?
I am also using the AT+CPAS . No use now.
So AT+CPAS is returning 4 also? What about AT+CLCC? What about AT#ECAM?
If you wait longer for call termination?
I tried the CLCC , it gives he output call in active.
ECAM gives ERROR.
This problem still exists.
Now i have another problem, i am using DTMF and also audio output via Loud speaker ,
while in call, without presing DTMF keys the DTMF decodings happens and switches my Relay.
How to come out of this
