Hi All,
I am trying an application where i want to attend more than one call, put one call on hold and attend another call etc.
From the AT command spec i understand that AT+CHLD is the command which does that.
I am using SIM900. I am connecting modem to my laptop.
1. I called the number which is in the modem from one number.
2. Attend the call using ATA command
3. And called the same no from another mobile
4. Now i am able to get second call
5. Now when i send AT+CHLD=2<CR><LF> it just giving "Error"
AT+CHLD=0,1,2,3,4 nothing works.
From the spec
"Note These supplementary services are only applicable to tele service 11 (Speech: Telephony)."
I am not getting the point here.
Is it possible to achieve what i am trying to do here?
