Hello brother, today i came across your youtube channel, your videos are so informative. Please try to make a video on "How to Control a Appliance (like motor) from anywhere with ESP32" It can give you more views and i am also waiting
• read(): Reads one byte (ASCII value), non-blocking, for raw data. Example: char data = Serial.read(); • readString(): Reads all data as a string, blocking, for text. Example: String data = Serial.readString(); Key: read() = Byte-by-byte. readString() = Entire buffer.
SIM900A only supports 2G services, So if your SIM card has 2g services enable , that simcard will work, in India except jio all simcard companies provide 2g services along with 3G and 4g.
2g services, are very slow, I mean it took around 1 to 2 minute to establish connection via call Or to send message using 2G enabled GSM. Right or false? Please help
Sir ye code upload karne k baad Arduino UNO board ko computer se disconnect kar ke external power supply Dene pe ye code kaam nahi karta hai. Ye code tabhi use kar sakte hain jab serial monitor open hoga ya Arduino UNO PC se connect hoga. Prectical use to koi hoga hi nahi is code ka. Customer PC open kar ke to baithega nahi.
@@technolabelectronics battery se hi supply di hai sir 3.9V for sim800l and 11.7v for Arduino UNO. Mujhe lagta hai ki serial monitor connected hona chahiye. Is code me
one of the best video i found on youtube about gsm module tutorial
Thank you ❤️
Very details knowledge 😊thank you sir
Thank you
Bahut hi achcha video banaya bhai ji aapane
Sir, how to use vvm500 a7672 module for sms function ?

Okay sure I’ll make
SIM7600 I'm using isme continuously SIM76O0 aa raha hai FSM
Sir !This is a Very wonderful project . Can you make a video on gsm based smart dusbin
Sure I’ll make
What is the different between read( ) and readString( )?
• read(): Reads one byte (ASCII value), non-blocking, for raw data.
Example: char data = Serial.read();
• readString(): Reads all data as a string, blocking, for text.
Example: String data = Serial.readString();
Key: read() = Byte-by-byte. readString() = Entire buffer.
vides continue rkhiye sir
Promise bro 😎
Kindly Sir Video for ESP32

Is gsm sim 800L module and gprs sim 800L module both same ??
( module with blue colour board )
Yes both are same
Thank you for the reply ,
Should we use 2g or 3g or 4g sim card in gsm sim800L module ? And which company sim card ?
Hello sir ye to 5volt 2 amp se hi run hojata h
3.7 volt 2amp se bhi ho jaega
sir kindly make a video with stm32 microcontroller
Sure
Sir can you make it reversed that what I mean is if call is send to circuit and msg is send to phone
Yes I can make it
For gprs with this module, any video pls
Yes will do video soon, please subscribe channel
UA-cam per free video milte Hain lekin aap log passage dete Hain
Kya?
Sorry Bhai
Can we use gsm 800L sim gprs module instead of sim900A
Yes you can
@@technolabelectronics thank you for the reply ,
can we use 4g airtel sim in gsm sim 800L gprs module ?
Yes
@@technolabelectronics thank you
@@technolabelectronics thank you for the reply,
Can we use only gsm module instead of gsm shield ? Will there be any difference in output / working ?
only 2G Supported?
Yes
does work same in gsm800l
Yes
Sir mine gsm module is connected with sim card network led blinks every 3 seconds but the message is not sent in mobile..what to do?
Check your wiring connection
@@technolabelectronics u mean the connection?
Is the same code work for gsm800a module?
Yes
Is me sim kon use kar skte hai
Jio ko chod kr koi bhi
12th volt or 2 ampere current kaha se milega
Adapter se
jo sabke ghar me current aata hai vo kitna hota hai?
220volt
@@technolabelectronics please code to de dijiye
i have to make a college project but code nhi hai
Aaj code upload kar dunga
