Hi, I am using the EM7455 module. I am discovering that after changing the APN using the at+cgdcont= command, I need to have a rather long wait time before I issue the at!scact=1,1 command to start PDP connection. If not, the connection may not be start up correctly. That is, the at!scact? command will show that the connection is not up.
Have anyone else noticed this behavior and do I even need to reset the module after issuing the command to change the APN?
