If it is connected to the 40Pin pin, please pay attention to pull down the Flight Mode and PWR pins of SIM7600, that is, you need to initialize the Raspberry Pi pins, otherwise the module may enter directly after plugging in the Raspberry Pi. Raspberry Pi 4B connected to SIM7600CE 4G expansion boardġ. The hardware connection is shown in the following figure: Raspberry Pi 4B, 16GB SD card (burning image version: -raspbian-buster-full) Next, the process of Raspberry Pi using NDIS driver to surf the Internet through SIM7600 4G module will be introduced. The underlying implementation of this method is the same as ppp dial-up Internet access, and will not be described again. To the ppp0 network port, you can access the Internet through this network port. After the SIM7600 is powered on, dial up the pppd script to identify it. After configuring and running the relevant scripts, connect the SIM7600 with a USB cable. This method must depend on the Linux system, and is suitable for application scenarios that need to be developed using Linux network socket programming. Likewise, it is recommended to use this method for dial-up Internet access. This method is the official recommended way to access the Internet. The bottom layer of this method depends on the USB virtual serial port of SIM7600. network port, through which the Internet can be accessed. After SIM7600 is turned on, wwan0 can be recognized. After loading the driver into the kernel, connect SIM7600 and Jetson Nano with a USB cable. This method must depend on the Linux system and is suitable for application scenarios that need to be developed using Linux network socket programming. If the network application is not complicated and the amount of data is relatively small (such as transmitting sensor data to the server and receiving control commands from the server), the function can be quickly used by using AT commands. This method is suitable for microprocessors with limited resources, such as MCU, or for application scenarios with a relatively small amount of data, such as uploading sensor data to servers, cloud platforms, etc. Use AT commands to use encapsulated TCP, MQTT, HTTP(S) Through the SIM7600 module, Raspberry Pi can access the Internet wirelessly in the following ways: What are the ways to use the 4G module to access the Internet? 3.2 Compile and install the driver module file.3.1 Check the hardware connection and network connection (this step must be checked and confirmed).1.1 Use AT commands to use encapsulated TCP, MQTT, HTTP(S).1 What are the ways to use the 4G module to access the Internet?.
