User needs to use high speed transistors such as MMBT3904.
MODULE supports the following baud rates: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600,
115200, 230400, 460800, 921600, 3200000, 3686400, 4000000bps. The default band rate is
115200bps.
3.3.2 RI and DTR Behavior
The RI pin can be used to interrupt output signal to inform the host controller such as application CPU.
Normally RI will keep high level until certain conditions such as receiving SMS, or a URC report coming,
and then it will change to low level.
Figure 17: RI behaviour(SMS and URC report)
Normally RI will be kept at a high level until a voice call, then it will output periodic rectangular wave with
5900ms low level and 100ms high level. It will output this kind of periodic rectangular wave until the call is
answered or hung up.
