Setting Minimum Quality of Service

Hello Everyone,

Can someone help me to set the minimum QoS using AT+CGQMIN ?

Do I need to set this everytime before I use AT+CGATT=1 ? or only once when the initialize the module ?

Also, I am not able to understand the parameters better ? I have a stored data (not real time) and the data is sensitive and it should be lost. I use TCP Sockets to send it to the Loging Server.

I don’t want the Module to initiate a GPRS context when the rssi value (in AT+CSQ?) is below…say ‘8’. Insted of checking the rssi value everytime, can I would like to set the QoS so that the module takes care of that.

You help will be greatly apprecited.
