I have been working on sending SMS to multiple recipients through AT commands. I have been modifying the code that I attached to this post.
Last night I got to know from this site here that we ought to use the AT+CMSS in order to send multiple sms. And that it sends message from the sms storage area in sim. I tried through this way:
gsm.print("AT+CMGF=1\r");
delay(100);
gsm.println("AT + CMSS=3,\"*********\"");
gsm.println("AT + CMSS=3,\"***********\"");
gsm.println("AT + CMSS=3,\"**********\"");
delay(100);
gsm.println((char)26);
delay(100);
gsm.println();
delay(5000);
gsmpower();
It's working for me but only sending message to the first number. Can you please suggest me the way to use AT+CMSS command?

I wanted to know if there is any code to check if a sim800L successfully sends a text message. I will need this code so that every time my sim800L sends a text message successfully it would light up a LED light. I am also using a nodemcu-32S as my microcontroller and Arduino IDE.
here is my code for sending a text message
Serial.println(customKey);
Serial.println("SENDING CONFIRMATION TEXT");
sim800.print("AT+CMGF=1\r");
delay(1000);
sim800.print("AT+CMGS=\""+PHONE+"\"\r");
delay(1000);
sim800.print("Completed");
sim800.print(",");
sim800.print(orderID);
delay(100);
sim800.write(0x1A);
delay(1000);
Serial.println("SMS Sent Successfully.");
See AT command manual (found it online, I don't have the device myself) at chapter 4.2.5 AT+CMGS - it looks like it should response, incl. whenever it succeeded.
Trying to call or send sms to a number that's not a phone number with sim800l via arduino results to an error. Does anyone knows how i can send an sms to a three digit number(for example, a network provider's number.). I need it for a project.
how Send SMS to multiple recipients using Arduino & gsm module. when button press send message to multiple recipients.
You may be able to set each number you are sending to as individual strings however i don't know what libraries/hardware you are using so you'll have to be more specific I'm afraid.
I would like to know if there is anything like GCM for arduino.
I'm working on a project where I need to send push notifications to the arduino connected with WiFi shield. Arduino then will do some action based on the notification it gets or sync up with the server data.
Any advice on how I need to proceed would be helpful.
Thank you.
Yes you can send push notification to Arduino. There are multiple ways from where you can send push notification to Arduino.
I am using push notification from Parse.com.To send push notification from Parse just register with Parse.com and create account there.
Once you create account,you can send push notification from Parse dashboard.
To receive notification on Arduino you need to write sketch on Arduino, following is sketch for help.
Include Parse library to make sure following code will work.
/***************************************************************************************************************************
setup function
****************************************************************************************************************************/
void setup() {
Bridge.begin();
Serial.begin(9600);
while (!Serial);
Parse.begin("***E0uUjQkMa7nj5D5BALvzegzfyVNSG22BD2FJ", "umPSsggp5JgMFmSHfloewW5oixlM5ibt9LBS***");
// In this example, we associate this device with a pre-generated installation
Parse.getInstallationId();
Parse.startPushService();
}//setup function block
void loop() {
if (Parse.pushAvailable()) {
Serial.println("Start push");
ParsePush push = Parse.nextPush();
// Print whole JSON body
String message = push.getJSONBody();
// Serial.print("New push message size: ");
// Serial.println(message.length());
// Serial.print("New push message content: ");
Serial.println(message);
// Do something with the push
// IMPORTANT, close your push message
push.close();
checkStatus(message);
Serial.println("End Push");
}//if push notification block
} //loop
You can read documentation here https://parse.com/docs/arduino/guide#push-notifications.
I hope this will help.
You would have to run an HTTP server on the wifi shield which accepts requests, then send such a request from your outside system (command line on your desktop, IFTTT recipe, etc.)
I'm assuming this is one of the older 8bit Arduinos (since you mention the wifishield rather than something like the Yun with a Linux partition), so you will need to write a http server sketch on the Arduino.
Here is tutorial for a simple HTTP server with the wifi shield from arduino.cc

i have trouble with my SIM900A GSM
i can send one SMS successfully ("arrived in less than one minute")
but when i send another SMS after first one (delay more than one minute "it's not for bulk purpose") the second message take about 15 minutes or more to arrive to destination device.
in the same time i'm sending sms my phone to the same destination it's arrive directly all sim-card from the same operator
i have powered the gsm with 5v,2A power so i have no power problem.
any suggestion will be great
i'm using arduino
this my code :
Serial3.println("AT+CMGF=1");
delay(1000);
Serial3.println("AT+CMGS=\"+96279XXXXXX\"");
delay(1500);
Serial3.println("my message");
delay(1000);
Serial3.println((char)26);
delay(1000);
Serial3.println();
delay(5000);
It seems that it is an issue related to network. Try switching to another network.
As far as the modem accepts your request for sending sms and replies back with +CMGS response including the a number, it has performed its job well.
SMS are not meant to be a real time communication and operators delay them due to several reasons.
