i used sim 800 l gsm module. sms came and after some time . SMS has stopped. Please help me to solve this problem module is crashing after sending sms help me code
Hello good day. I want to ask something about the GSM. Is it possible for this to work with only arduino + gsm + raspberry pi. Because I cant connect the gsm to a computer while it is operating
Hi I trying sim800l and sim800l v2 both module but they unable to interact with Arduino and i am not getting any response on serial monitor why? I am making a call and it's ringing even my MSG also delivered to sim800l module what may be the problem?
sim800l não acende a luz LED. Estou trabalhando com 4.1v e 2a. O LED pisca apenas se o chip for considerado ou o LED deve piscar mesmo sem chip??? thanks
I tried this but it didn't work in serial monitor it just shows initialising and nothing after that and my gsm module just keeps blinking can u please help me with this
Hi Ahmad Great In previous programs, you used delay (); command . In this program, you used the waitForResponse (); function. Would you explain this difference?
Arduino do nothing while in delay time. so, to increase the performance of the program I have used waitForResponse() function without using any delay(). But this function is under development. I am working on it to make the code more efficient.
hi we have made a project on arduino based obstacle avoiding robot with crash detection and gps system . we have used sim 800l for the gps tracking n sms alert but it doesn't seem to work in our areaa(we use 2g sim) so what changes can we make to improve this??
Hi, i'm from banglore, im also working on arduino based crash detection and gps system, but gps system is not working, i dont have 2g sim either, did u find an alternative for this problem, if u find, please let me know, i too will update if i figure it out
In some time my sim800l module is disconnected from the network automatically after it will connected, but the arduino can't work after the connection because of all the AT commands are placed in setup function, so how to I use when the GSM MODULE reconnected to network & work properly with ardunio
Hi, i do have sim800l using zong sim.. for last 4days i was able to send sms through sim800 but after that it stop connecting to network , red led i blinking every second. What could be the problem its been two days i am working on this. Kindly help me..
Hi, i have a problem with using any AT commands When i used your code Mr Ahmad in serial monitor i can see only the word "Initializing.." and that's all there is no At commands work Pls help me, what did I do wrong
I have a question, I need advice. I want to control pump and fan remotely by GSM. What do you use as a controller? stm 32 . adruino nano ? The choice in terms of cost and ease of programming and installation.
@@AhmadLogs anather qsn, i am not getting signal from network as led blink in 1sec. Sim is ok and it is 2g active sim. Attached a 3.9vollt lithium battery. Stil problem there but in at command the arduino shoows the sim number. It means sim reading is ok.
@@Sekhar_Home 1. some to the AT commands always works even if your gsm module not connected to the network. 2. try another 2g sim card just for testing. 3. you need to try another sim800l module. it might be damaged.

which mobile phone you have used. the sms content are simple text and all the mobile phone support text. so it is strange. have you made any change in the code.

Hi, my sim800l not gives at ok messages. İt writes initializing... And ? this question marks 3 time
Great video
My gsm is only Blinking only onec when powered up
I tried powering up with Buck converter but didn't helped
What to do ?
use a battery 3.7v. if you are using buck converter the set the output voltages to 4.2 volts.
Serial monitor is stuck to Initializing
And even I am not getting any message or call
Mine also same. Have you found any solution??
I tried this but it didn't work in serial monitor it just shows initialising and nothing after that and my gsm module just keeps blinking can u please help me with this
most of the time this is power supply issue. provicde stable 3.7 to 4.4V,
is there a code just for mq2 sensor?
Is sim800l also comes with 5v tolerance? If yes then please tell me that how to check this 5v tolerance property . Please
sim800l v2 is a 5v tolerance module. it is a 7 pin module
I tested the circuit several times, everything is fine, but the SMS is not received, it rings and is available, and the SMS is sent.
for esp32
try following at the end of the setup function.
sim800.println("AT+CNMI=1,2,0,0,0");

Hi, Bro how to get 2g sim nowadays because i only have 4g sims
It's okay to use 4g Sim ,you cannot access the internet only.
Ahmad Bro I'm Using 3.7V li-ion battery but its LED is still blinking for 7 times and repeat
use short length wires from battery to sim800l or try another sim card

no
