GSM - sending sms speed is blocked by the incoming call
Posted on 2007-04-09
I am developing software to send bulk sms. I have motorola L2 mobile. I have one library downloaded from sourceforge.net Which sends AT commands to the modem. When the mobile is started to send messages, It sends 30 to 34 messages per minute. When it receives a single incoming call it is getting slow. It sends only 6 to 10 messages per minute. Even after the call ends.
After ending the voice call also it didn't pick up the previous speed.
Before voice call - 30 to 34 sms per minute.
During the voice call - 1 to 3 sms per minute.
After ending the voice call - 6 to 10 sms per minute.
My problem is, why it didn't send 30 - 34 sms per minute even after ending the voice call.
Now I need to keep the same speed when it started to send.
Or atleast can i block the all incoming calls (even missed calls also). Is there any AT commands to avoid incoming calls or any other go?
1) Visual Studio 2005 with DotNet Framework 2.0 (C#.Net)

3) Motorola L2 mobile
4) SMSLib Library as core, downloaded from SourceForge.net
Thanks in advance.
