How to send data to web server using sim900a?
This is an IoT based project in which we will use GPRS, present on the GSM Module SIM900A board, to send some data to the web service on the internet.
How to send sim800 / 900 GPRS data in JSON format?
You can check the post here: Send SIM800/900 GPRS Data to Thingspeak with Arduino But today we will interface the SIM800/900 GSM GPRS Module with Arduino and develop a code to send the data to any web address or web server using API. We need to send the data in JSON format as direct sending of a string data looks difficult.
How to do browser-based upload using AWS Signature?
You can provide any key name that starts with user/user1. For example, user/user1/MyPhoto.jpg . The ACL must be set to public-read . If the upload succeeds, the user’s browser is redirected to http://sigv4examplebucket.s3.amazonaws.com/successful_upload.html .
How to send data from sim800 to Arduino?
But today we will interface the SIM800/900 GSM GPRS Module with Arduino and develop a code to send the data to any web address or web server using API. We need to send the data in JSON format as direct sending of a string data looks difficult. The whole process and the final code is explained in this post.
How to send data to SparkFun server using Arduino?
For Sending Data to SparkFun Server, we need to interface Keypad and GSM module to Arduino. In this project we have used Arduino to taking input string from the keypad and sending commands to GSM/GPRS module. GSM/GPRS is used to communicate with the Internet for sending data to the Sparkfun server.
How to send data from SIM card to server?
Checking SIM card has data pack or balance AT+CIFSR :- get IP (sometimes without this command GSM do not work so use this command) AT+CIPSTART = ”TCP”,”SERVER IP”,”PORT” :- is used for creating TCP connection with the server that we provide in place of SERVER IP AT+CIPSEND :- this command is used for sending data to the server.
