GSM : Part 2 (Controlling GSM using Arduino's Serial Monitor)

In this video, I will be showing how to control a SIM900 Mini GSM Module by using Arduino's Serial Monitor alongside with some tips on how we can improvise GSM's responses to our need.

Sir please help me... My serial monitor keeps saying AT ERROR AT ERROR

[@KricksStories]

if network LED doesn't blink what to do.And only DC-PMR led is on in SIM 900a

Hello sir, My sim module doesn't show any response after sending at commands.. My project is gas leakage detection and the gas readings are displayed in serial monitor simultaneously so will that suppress the sim module's response.. please do help me sir 😢.. I am stuck with it for past 3-4 weeks 😭

good day do you have sim900a bulk sms tutorial ? thankyou

Hy big hommie, Can you flash this module? make a tutorial please, i can't flash it.

[@KricksStories]

excuse me sir i am using this gsm 900a for my science project.Actually the problem is that my gsm is not sending SMS to a desired person what should i do

[@electronicseternity9210]

Well that's a very general question. Maybe you can try to spot where the problem is. Go thru part1,2 and 3 to see if you could replicate the same from your end

Hello sir , my gsm 900a is not blinking(D6) . It just glows when it finds the signal(connection). What is the problem? . Is there anyother way to contact you?

[@jumbo999614]

Probably not enough current. use 2 different power sources. One for Arduino and one for GSM and don't forget to link Ground between Arduino and GSM.

[@syaduinotech3681]

Can you please help me? When I enter the AT command like AT and enter, the output becoming "kC⸮ ", do you know why this thing happen? Please help and advise, I am quite upset, because cannot fix this weird output coming out from serial monitor

[@electronicseternity9210]

Have you tried varying the Serial Monitor configuration and see how the outcome varies.

[@syaduinotech3681]

@@electronicseternity9210 yes sir, all that had been done, changing laptop, mac, pc, and change each baudrate also result similar findings or even worst. Can you please do help me. So far when I call the number from other phone, the serial monitor indicate something, but the value/ character display was not understandable..

[@electronicseternity9210]

@@syaduinotech3681 Tbh, the characters are not understandable for me too. I'd suggest contacting your SIM900 provider. I did the same anytime I need info on my gsm module.

[@syaduinotech3681]

@@electronicseternity9210 thanks sir. Your ideas make sense.. i re do it again, based on your sketch and change one baudrate by one.. until i got mine 38400 and its well done and able to be used. Tq sir.. your response and sharing very much appreciated

Thanks for sharing such an Awesome project. The link shared to download the code is not operational . Please check the link or share the code. Thanks & kind regards.

[@electronicseternity9210]

Not sure what you mean by not operational. The code is functional from my end. Maybe can share more info on your issue ;)
