<\/figure><\/div>\n\n\nCompatibility<\/strong><\/p>\n\n\n\n This board supports 2G, LTE CAT-M1, and NB-IoT protocols. You can go to the following links to check if any of these protocols are supported in your country:<\/p>\n\n\n\n Check network protocols supported in your country;<\/a><\/p>\n\n\n\n Check NB-IoT providers in your country.<\/a><\/p>\n<\/div>\n\n\n\n The LILYGO T-SIM7000G<\/a> is an ESP32 development board with a SIM7000G chip. This adds GPS, GPRS, LTE CAT-M1, and NB-IoT protocols to your board. This means that with this board you can send SMS, get location and time using GPS, and connect it to the internet using a SIM card data plan. This board doesn’t support phone calls.<\/p>\n\n\n Besides the SIM7000G module, the board also comes with some interesting features like a battery holder for a 18650 battery, a battery charging circuit where you can connect solar panels to recharge the battery, and a microSD card slot that can be useful for data logging projects or to save configuration settings.<\/p>\n\n\n\n For a more in-depth introduction, we recommend following the getting started guide:<\/p>\n\n\n\n Where to buy LILYGO T-SIM7000G ESP32?<\/strong><\/p>\n\n\n\n Check the following link:<\/p>\n\n\n\n All stores in the previous link should sell the latest version, but double-check the product page, just in case the seller changes something.<\/p>\n\n\n You can use the preceding links or go directly to MakerAdvisor.com\/tools<\/a> to find all the parts for your projects at the best price!<\/p> The ESP32 communicates with the SIM7000G chip by sending AT commands via serial communication. You don’t need a library, you can simply establish a serial communication with the module and start sending AT commands. There’s a manual with all the SIM7000G AT commands:<\/p>\n\n\n\n However, it might be more practical to use a library. For example, the TinyGSM<\/a> library knows which commands to send, and how to handle AT responses, and wraps that into the standard Arduino Client interface\u2014that’s the library we’ll use in this tutorial.<\/p>\n\n\n\n Open your Arduino IDE and go to Sketch <\/strong>> Include Library<\/strong> > Manage Libraries<\/strong>. The Library Manager should open. Search for TinyGSM<\/strong>. Select the TinyGSM library by Volodymyr Shymanskyy.<\/p>\n\n\n You also need to install the StreamDebugger library. Go to Sketch <\/strong>> Include Library<\/strong> > Manage Libraries<\/strong>, search for StreamDebugger<\/strong>, and install it.<\/p>\n\n\n To get GPS data with your board, you don’t need to connect a SIM card. You only need to connect the GPS antenna to the board.<\/p>\n\n\n Copy the following code to your Arduino IDE.<\/p>\n\n\n View raw code<\/a><\/p>\n\n\n\n Let’s take a quick look at the relevant parts of the code.<\/p>\n\n\n\n First, you need to define the module you’re using. The library is compatible with many different modules. To use the SIM7000G, include the following line:<\/p>\n\n\n\n Include the TinyGSM library.<\/p>\n\n\n\n The following lines set the board pins to control the modem:<\/p>\n\n\n\n You need to create two Serial instances. One for the Serial Monitor which we’ll call SerialMon, and another to communicate with the modem via AT commands, which we call SerialAT<\/span>.<\/p>\n\n\n\n Create a TinyGSM<\/span> instance called modem on the SerialAT<\/span>.<\/p>\n\n\n\n Initialize the Serial Monitor at a baud rate of 115200.<\/p>\n\n\n\n Turn on the modem by setting the power pin to HIGH and LOW at a specific interval.<\/p>\n\n\n\n Initialize a Serial communication with the modem on the RX and TX pins we defined earlier.<\/p>\n\n\n\n Restart or init the modem:<\/p>\n\n\n\n Get some modem info using the getModemName()<\/span> and getModemInfo()<\/span> methods. These lines are optional and you don’t actually need them to get GPS data.<\/p>\n\n\n\n There are two versions of the LILYGO SIM7000G ESP32 board. The latest comes with active GPS antenna power control\u2014when the module GPIO 4 is not turned on the antenna consumes only the static current of the LDO. This means we need to turn GPIO 4 on before getting GPS data to power the antenna. That’s what the next lines do:<\/p>\n\n\n\n You can start GPS using the enableGPS()<\/span> method.<\/p>\n\n\n\n Then, we create variables where we’ll save the GPS data. We’ll get latitude, longitude, speed, altitude, visible satellites, used satellites, accuracy, and date and time.<\/p>\n\n\n\n The following line gets GPS data using the getGPS()<\/span> method and saves the values on the right variables.<\/p>\n\n\n\n Then, we simply print the values on the Serial Monitor. Now that you have the relevant information saved on variables, it’s easy to modify this project for your own needs. For example, a GPS tracker, GPS data logger, etc.<\/p>\n\n\n\n You can also get all raw data returned by the GPS using the getGPRSraw()<\/span> method. <\/p>\n\n\n\n When you’re done using GPS, you can turn it off using the disableGPS()<\/span> method:<\/p>\n\n\n\n And finally, turn off the power to the antenna by turning GPIO 4 off:<\/p>\n\n\n\n In your Arduino IDE, go to Tools <\/strong>> Boards <\/strong>and select the ESP32 Dev Module<\/strong>. Select the COM port in Tools <\/strong>> Port<\/strong>.<\/p>\n\n\n\n Then, upload the code to your board.<\/p>\n\n\n Open the Serial Monitor at a baud rate of 115200 and press the on-board RST button to restart the board. Place your board outside or next to a window or door so that it can catch satellite signals.<\/p>\n\n\n\n It may take some time until it can get some GPS data, as you can see in the screenshot of my Serial Monitor.<\/p>\n\n\n As you can see, it gets latitude, longitude, speed, altitude, visible satellites, number of used satellites to get position, accuracy, and UTC date and time. The longitude and latitude I got were very accurate. So, in my case, it was working pretty well to get the location.<\/p>\n\n\n\n It also outputs the complete GNSS navigation information parsed from NMEA sentences (that you can’t see above because the Serial Monitor window is too small). NMEA stands for National Marine Electronics Association, and in the world of GPS, it is a standard data format supported by GPS manufacturers. The output is as follows. The commas separate different values. <\/p>\n\n\n\n Here’s what each value means, in order:<\/p>\n\n\n\n You can learn more about these parameters and possible values by checking the AT+CGNSINF<\/strong> AT command on the SIM7000G AT commands manual.<\/p>\n\n\n\n In this tutorial, you learned how to use the LILYGO T-SIM7000G ESP32 board to get GPS data. We showed you a simple example that prints the GPS data in the Serial Monitor. The idea is to modify the example and apply it to your own projects. It should also be compatible with a “regular” ESP32 board connected to a separate SIM7000G module.<\/p>\n\n\n\n The ESP32 T-SIM7000G board features will allow you to build a wide variety of projects taking into account that it can connect to the internet in remote locations using a SIM card data plan and send SMS. The fact that it can use a battery and solar panels for charging is also great, and the microSD card can also be handy for datalogging or saving configuration settings.<\/p>\n\n\n\n We hope you found this tutorial useful.
