I have a problem, I'm new to Arduino and I'm totally a beginner.
I bought a SIM900 Quad-band GSM / GPRS Shield for Arduino (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=221176159800&ssPageName=ADME:X:RTQ:US:1123) and I have two problems.
(I use the test code that is found in the library)
First
the device does not read every message, but only a few. one read and then 3 does not, then 2 read and then 4 do not read .....
Second
I do not know how to connect to xively, no examples.
I know how to connect and send data via an ethernet shield, but with SIM900 Quad-band GSM / GPRS Shield do not know how.
I download the library from http://www.gsmlib.org/download.html and fix the first problem with sms.
but I do not find a solution to the second problem, and I can not find and I need a simple example to send data to xively.
So if anyone can help I would be grateful
You'll need to learn how to have the SIM900 perform HTTP operations. Study the example shown in Step 8 at this Cooking Hacks tutorial
For posting data to Xively, study this example.
You'll need to merge how you communicate from the SIM900 with the right HTTP sequences in order to upload data to Xively.

I'am working on an IOT project. The goal is to communicate between two openmotes (one is the server and one is the client). When the client receives some data, it is supposed to pass it to an arduino to activate different controllers (like a motor, some leds ...). So, I wanna send data from a openmote to an arduino. The idea is to use a bus. The openmote is the master and the arduino is the slave. Do you have any idea how to do this ? I can't find any documentation fro the open mote part. I thought about using the serial UART but i don't have any idea how to do that.
Thank you !
If anyone is looking for an answer, it is possible to activate the UART 1 on the open mote and to send data to the arduino using that bus. You have to pay attention to the speed you are using on both sides.You can refer to this file to see the functions to use: https://github.com/contiki-os/contiki/blob/master/examples/cc2538-common/test-uart.c
I'm using Arduino 101 and a HM-10 Module(BLE). I want to make an android app to send and receive data from Arduino via this Bluetooth module.
I was unable send data or receive data. I was able to connect to module.
Can you tell me a good tutorial how to do it? or to provide some useful information
I had to figure with the same problem currently on IOS, but i have found a good example Project to get startet. Look for one on the internet. Best is to look for a example that is basically a Serial Monitor/Terminal. After you have found your Example you should be able to modify it after your needs.
I am trying to stream some sensor data to Dweet.io using my Arduino connected to a SIM900 GSM/GPRS module. I am able to access internet, load data, check GPRS connectivity etc from my Arduino board. Could someone specifically tell me the syntax to post data onto dweet.io?
Instead of Using the AT commands use this library its easier and Nice https://github.com/amcewen/HttpClient
Dweet.io needs GET commands to send and receive data.
I have some sensors connected to my ardunio uno and get periodically data from that sensors now I wanted to send that data to cloud.
I dont have any idea about how should I connect my arduino to Internet using GSM. How should I solve this problem or any alternative is there.
Just get an appropriate shield (like this one) and follow the documents included with it. The linked shield includes some basic service plan as part of the purchase. Once connected, it's just like using any other TCP/IP application.
I'm kinda new to this forum.
I have an Arduino UNO and a CC3000 wifi shield from Adafruit.I want to send messages to a laptop or specfic IP address via wifi. Not complex messages or anything, just an alert or a flag. Can anyone point me in the right direction? I'm not really sure of the protocol for sending something like this, or where I would even be sending it to.
I've used a CC3000 WiFi Shield and made a temperature plotter which you can read about here.
But, I think you could configure your Arduino as a webserver (there are pre-made sketches with the examples) and figure out a way to install PHP on it for it's mailing function? You could also look at services such as Zapier and IFTTT to send emails/text message alerts to you.
For a PHP tutorial using pcduino.
This type of project I think would be better suited for a Raspberry Pi since it's already Internet ready.
I hope this will point you in a better direction.
