Description
This command sets and queries the priority of voice call and data service.
15.12.3
Defined Values
<mode>:
0: voice call prefer (default value)
In this state, an incoming voice call will suspend the data transmission. If data service
is not in transparent transmission mode, all ports (PCUI port, MODEM port, and UART
port) will report RING message. If data service is in transparent transmission mode, all
ports will report RING message except the port which is processing data service, and
the RING pin is dredged. The data transmission will keep on going after stopping the
voice call. But there is one risk that the transmitted data maybe loss during the
process of voice call, only the last packet(less than 1600 byte) can be sent
successfully.
1: data service prefer
In this state, after using ^IPINIT command initial the IPSTACK, an incoming voice call
will be hang up by the module automatically.
