How to send that data to localhost server

[@kdescala1627]

Hi Tesalex. Thank you for sharing this tutorial. But I seemed to have a problem. The the matrix won't display the message I sent and also on the serial monitor. I hope you can help me. Our presentation will be next week and I need to finish this before our presentation. I really hope you can help me with this. Thank you so much. By the way I am using sim900.

Can i can use large dot matrix display instead of it plz i want to do with my college project

[@mhdghozaliali6954]

sister why display md_max72xx have you different from me. but I also downloaded on Github site. can you give me the library you are using. Please help. thank you

[@pucuk.nusantara]

do i have to merge the files "GSM_Message.ino" and "GSM_DMD_SMS.ino"? or upload them separately?

[@Tesalex]

Separately. GSM_Mesaage.ino is only for checking GSM Module.

[@pucuk.nusantara]

hi, I have followed all the order carefully, but the sms is not accepted sim800l and on the serial monitor no incoming sms notifications, when the status sms already sent and also is there no data being changed in the file "GSM_DMD_SMS.ino" ?

Hello Will u send me code for arduino

[@RakeshRoy-cb7km]

Your voice is very sweet 😋, What is your name ?

[@nurizzwatifmohdhassan9422]

Hii Tesalex ! Can I use your code for SIM900a or just SIM800l ? Please reply me asap....I need to submit my project in 2 weeks huhuhu thanks in advance....

[@Tesalex]

Hey! Yes you can use it for both the modules as both have same set of AT commands.

[@nurizzwatifmohdhassan9422]

Hey ! I already tried your code with my SIM900a and it's woking very well. I just adjust the pin. Thanks. Now, I had a new problem which is my dot matrix not receive and display my message from my phone. It's only receive and display a message that I sent on serial monitor. Can you help me ? Thanks again.

[@Tesalex]

First, verify that your GSM module is receiving the messages correctly using just serial monitor and nothing else must be connected to Arduino. In the same way, check the DMD separately. The problem will be easy to find this way.

[@Tesalex]

Have you added both libraries required for the Dot Matrix Display? If yes, then have you done the step demonstrated at 2:43? Most probably ,this is the step you are missing.

[@nurizzwatifmohdhassan9422]

Oh okay, now I get it when I do separately but when I try your code that combining them, it's still cannot receive and display my message from my phone. The pin for my SIM900a is 9 and 10 while the pin for my DMD is 10,11 and 13.

Error is there while uploading the program

[@Tesalex]

What is the error? Make sure your added the required libraries.
