![]() ![]() Receive SMS with AT Commands using Sim900 and Arduino Moreover, also have a look at Send SMS with Sim900D in Proteus ISIS in which I have designed a simulation of sms sending in Proteus ISIS. You must also check GSM Library for Proteus, using this library you can easily simulate your GSM module in Proteus ISIS. ![]() So, let’s get started with How to receive SMS with AT Commands using SIM900 and Arduino. I have also posted tutorial on How to Receive SMS with SIM900 & PIC Microcontroller and How to Send SMS with PIC Microcontroller so if you are working on PIC Microcontroller then you must give it a look. We can also interface our GSM board with other microcontrollers like PIC Microcontroller as well as 8051 Microcontroller. ![]() We have designed this code after a lot of effort that’s why this code isn’t free but we haven’t placed a very small amount of $20 so that engineering students can also buy it easily. So, first of all we will place a check that whenever someone sends a message to our SIM900 module, we get notified and after that we will extract the message and the mobile number of sender. Now, after you get notified, there’s a need to read the message as well and also who has sent this message. Today, we are gonna cover this how to receive SMS with AT Commands in detail. So, ideally whenever anyone send a message to your SIM900 module, you should get notified. But receiving a text message on your SIM900 shield is a bit difficult because now you need to place a check when user will send a message. Sending SMS is quite easy, you just need to write some AT commands and write the message you wanna send and hit the Cntrl + Z and it will be sent. I have already posted a tutorial on How to Send SMS with Arduino UNO and Sim900, so now we are gonna check the opposite. ![]() Today, as the name suggests, I am gonna post on how to Receive SMS with AT Commands using Sim900 and Arduino. While(Serial.Hello friends, hope you all are fine and having good health. InByte = Serial.read() // Wait for the start of the message ← this is written wrong, but even after I got it to compile it didn’t workĪnd I’ve also tried searching google for “read text from serial” and other terms, only finding bits about how to read a character at a time, etc. I’ve been on the internet long enough to know how this works, so please dont flame me with “do a search” because I’ve looked at the following resources: I’ve been scouring the internet, and these forums, trying to understand how to use serial.read to read in text from the serial port, and upon receving the enter key (carriage return?) send the string to a Sure 3216 display. ![]()
