Concurrent Service Application Scenarios
Data transmission through the UART
port is suspended, and all ports
present the Ring indication.
After the call is hung up, data
transmission through the UART port
is resumed. Packets
received/transmitted when data
transmission is suspended will not be
lost.
The module enters transparent
transmission mode to transmit data
continuously.
(An MT call comes in)
By default, voice calls have priority
over data transmission (which is set
by AT^DVCFG=0). Data
transmission through the UART port
is suspended, and the USB (PCUI
and MODEM) ports present Ring
indications.
After the voice call is hung up,
resumes data transmission through
the UART port.
Sets data transmission to have
priority over voice calls.
