Unable to establish data call With MC7304

[sukumar441]

I am working on MC7304 EVM board. I am using aircel 3g sim and trying to use data call but don’t know what i have to do after the following steps:

1. AT+CGACT=1,1 for PDP context activate
2. AT+CGATT=1 for PS attach
   after this i’m trying to connect using ATD99# or ATD99***1# then it shows CONNECT 100000000.

After this, I am unable to write any AT command.

Is there any document to use data command or steps for making data call?

Hi,
After ‘CONNECT 100000000’, your module entered into data mode. To give any other AT command, you have to come out of data mode by giving ‘+++’.
