The alternative way is to use a p-MOSFET to control the module's power, as shown in Figure 3-4.
When the external MCU detects the exceptions such as no response from the module or the disconnection
of GPRS, power off/on can rectify the module exceptions.
In Figure 3-4, the module is powered on when GPRS_EN is set to high level.
