In this video
we are getting to know about the multipurpose development board i.e. LILYGO - TTGO SIM 7000G Module .We are testing the network signal , and the internet connectivity weather it is connected or not. We are using Airtel 4g micro sim card and attaching it to the dev board. Further we will get to know more projects on this dev board .
You can copy the code from code given below.

Hi, thank you . Can anyone tell me how i can power the board trough the pins? There is nothing to be found in the manual ! There is no VIN pin, only VBAT, which should only be 4.2v max? very confusing
Hola , un gusto saludarte y felicitarte por la extraordinaria información que compartes, bueno comentarte que seguí al pie de la letra todo el ejemplo y no me pudo salir, al parecer no hay comunicación entre el SIM7000G con el ESP32 incluso por el pin 4 no envía la señal de POWER.
Nota: la programación si se llega a completar, sin embargo no se prenden las luces de color rojo de GPS y del SIM. Lo que se queda prendido en todo momento es la luz de color azul y verde.
Gracias por tu tiempo espero tu gentil respuesta y pongo en copia lo que me sale en en el monitor serial.

Hello Friend ,
Thank you for your kind words .
As per your written comments I can sense few thing might have happened and you can do few things for it i.e.
Things to noted-
1. The green led indicates the power on board .
2. Blue Led indicates the Esp32 activity .
3. On other two led's , one which blinks shows the GSM network establishment and other red led shows power in GPS module .
Give it a try -
1. Check whether device is properly working or not by uploading a simple blink program in esp32 .
2. Check the Usb cable you are using for communication.
3. Select correct baud rate .
4. Use latest version of Arduino Ide or try to use alternate version.
I hope you find the solution for your problem.
Good luck.
@@techwarmup Gracias por responder, realice lo me indicaste y la programación fue completada, sin embargo el ESP no responde, intento con varias programaciones y siempre sale lo mismo.

@@mizraimdamiancasas7160 i would suggest to start with a new TTGO board if the problem is repetitive.
What cable are you using? None of the usb c to usb a cables I have make the board light up.
I have used ordinary Type C cable .Better you try with New Cable or try with battery and turn on . If still it doesn't lit up , board might be dead .
Can this module be powered by supplying a regulated 3.3v to the 3V3 pin ?
And if yes, would it all power up, including the GSM module ?
For any external power supply (3.3v - 9v ) you can use VIN and GND pin. And using that pin gsm and gps will also work .
👍
@@techwarmup my query is about the 3.3v pin used as an input for power.
@@arnoldmuhairwe Yes you can use 3.3v pin
but that won't be safe for the device if you got any voltage fluctuations device might collapse.
As well as If you use multiple servo it won't provide enough current and voltage .
@@techwarmup I could use capacitors to smoothen the ripples and use a 3.3v LDO to supply a steady 3.3v supply. My worry is whether the GSM would be able to power up as well from that arrangement.
@@arnoldmuhairwe were you able to find anything ?
Hi. Did u have a protues library for this model. I want to make a pcb
No
Can you use the USB/Vin power to charge the lithium cell?
Yes you can use Vin Pin to charge the batteries but the charging speed might be slow . Best of luck 👍
HOW DO I PUT A CAMERA IN THIS BOARD
Hello, your video is very good! Congratulations! I live in Brazil and I don't know what to put in the apn[] value on line 25. Can you help me?
Hello , Thank you for kind words ,
1. First ,Which Sim Card you are using ?
2 . You can search APN in Google for whichever Operator's SIM Card you are using .
Go to 4:32
can you use this to make voice call?
Yes it's possible
@@techwarmup how do you connect the mic and speaker?
hi sir, can this module be used to send data to firebase?
Do you mean firebase.google.com ?
If yes then Yes you can send data to cloud using any suitable server like blueHost or AWS then you can fetch the data from server to your app or browser.
HOW ABOUT OTA UPDATE???
What is your exact query ? Explain in brief so that i can help. you can dm me @ instagram.com/techwarmup?igshid=OGU0MmVlOWVjOQ%3D%3D

40$ - is that a cheap module? I doubt
compared to all of the 4g modules out there this might be the cheapest, sure you can get a 2g for half the price but most countries are dropping 2g
