Hello... All the Wirings/Libraries/Codes I've used are in the link below the video as usual, Don't forget to Subscribe ... some other videos about this module are coming.
@@rahilsaifi5660 Hello, make sure the wiring, libraries and code are well. Try to send some AT commands from the Arduino IDE serial monitor and check for the feedback, AT the module should tell you "OK" check the tutorial and focus the SerialCom function ruclips.net/video/SsfJsdjfaqE/видео.html (I can't remember if I used it in this one).
Hello!! Great video.🙌 I'm using the same module (sim800l v2) Can u pls tell me what you used to provide power supply? How much current and voltage rating should I provide for it to function properly?
Amazing video SurtrTech!....A quick question please, I am also using this sim800l evb v2 board also, but have no idea how to put it in sleep mode....Does anyone know how please?
Hello Yassine, first thanks for this Chanel. So i have bought Sim900 and sim 800 i have uses Maroc telecom card sim 4G+ the problem that shield didn't work. I have question which card sim have you used i saw this is NW but it s 4g too?

Of course you need one, and it shouldn't be locked with a pin code, and make sure it has enough credit to be able to send a SMS like a phone. I mentionned that quickly at 1:25.
As long as it can provide the required amps to work, all 5V source are OK. To use Vin the input voltage should be above 6.2V, recommended 9-12V, since the converter has 5V output, I can use it directly with 5V pin of the Arduino.
@@SurtrTech Thanks so much for the speedy reply, I really enjoy your channel. I wired up the initial circuit you demonstrated in this video, and inserted a sim. I am waiting on delivery of my battery, so just powered the module via the arduino 5V I had the 3 second delay red led flashing. so I believe it had signal, but when the button in pressed the serial monitor displayed "Sending SMS" immediatley followed by "Text Sent" hence just the serial prints in the code and no information from the module - could this be due to using the arduino to power the module as you mentioned in your video?
@@BenGuardian Thank you, the module can actually be powered by the Arduino, but it's not recommended to do so, for me it worked few times like that and never again, that's why I used an external battery and converter. On your phone do you receive any SMS or no? And remember there are 2 LEDs, one should be always ON, if it's turned OFF it means that the module has restarted and it's probably due to undervoltage... If you receive all SMS normally, it's OK. For the feedback from the module, you can check my other video about send and receive SMS (ruclips.net/video/SsfJsdjfaqE/видео.html ), I used a function called "Serialcom()", and can send commands and receive feedback using the serial monitor. void Serialcom() { delay(500); while(Serial.available()) // IDE serial l serial sim800L { sim800l.write(Serial.read());//Forward what Serial received to Software Serial Port } while(sim800l.available()) //serialsim800L l serial dial IDE { Serial.write(sim800l.read());//Forward what Software Serial received to Serial Port } }
@SurtrTech When powering up, the left most LED comes on bright then dims quite significantly but does stay on permanently. The second LED blinks every 3 seconds indicating it has signal
Great video, unfortunately I know the electronics well but not the programming as well although I slowly learn to learn. I have all the material at home and also the AM2301 module (DHT21), so I would like to do this project for 'with a diversity', remotely call, when I want, the system (ARDUINO + SIM + DHT21) without sending with the button. I hope I have explained myself. Can you help me?, thanks de IK1CFJ, Biagio.
Hello, yes I know what you meant... I will try to do this next, maybe send or call the Arduino and then it sends you data back, it's really interesting to do! If I succed, I will notify you.
Once the SIM800L goes back to standby mode it can send another SMS if the button is pressed, so you need to consider the duration of the whole sequence (it takes few seconds: 3-5s)
The pins 0/1 are used for communication with the PC (via USB), since I want to see things on the serial monitor so I used pin 2/3 (as Software Serial) to communicate with the module.
You made sure you have enough credit, and the card is not protected by a pin code? Also can happen sometimes to have very low signal reception especially if used without the antenna...

Sir, if we send the message from sim800l to android phone, then that show does not happen, please reply me.

Don't you need a SIM card to connect to the cell service provider ? I look quickly on the website for documentation but couldn't find it.
Of course you need one, and it shouldn't be locked with a pin code, and make sure it has enough credit to be able to send a SMS like a phone.

3.7 lithimum battery and boost to 5V okay?
Also why don't you use vin to power the arduino from the battery? I thought the 5V pin was for output only
As long as it can provide the required amps to work, all 5V source are OK.
To use Vin the input voltage should be above 6.2V, recommended 9-12V, since the converter has 5V output, I can use it directly with 5V pin of the Arduino.

sim800l.write(Serial.read());//Forward what Serial received to Software Serial Port

WHAT IF YOU CONTINUOUSLY PRESS the button. Will it send many more texts??
Once the SIM800L goes back to standby mode it can send another SMS if the button is pressed, so you need to consider the duration of the whole sequence (it takes few seconds: 3-5s)
Aren't pins 1 and 0 tx and rx on arduino?
The pins 0/1 are used for communication with the PC (via USB), since I want to see things on the serial monitor so I used pin 2/3 (as Software Serial) to communicate with the module.
I tried to with4g giffgaff card in sim800L V1 but no luck
You made sure you have enough credit, and the card is not protected by a pin code? Also can happen sometimes to have very low signal reception especially if used without the antenna...
SurtrTech i ordered a 1pmobile sim card, works perfectly 👍
If you're looking for send and receive here's the tutorial: ruclips.net/video/SsfJsdjfaqE/видео.html
