I was finally able to get the prowlapp HTTP GET API working with the state machine machine based serial modem interface I wrote in Python running on my PC. I will be adding the updated files to my github repository very soon.
Here is a screen shot of the received message in iOS:
Next step, get this working with native Arduino code.
Ever since I got TCP data rx/tx working on the SparkFun SM5100b GSM/GPRS shield I have been prepping for the next step which is to get HTTP GET requests working. The problem I seem to be having here is that the HTTP server disconnects the TCP connection immediately after sending the response to the GET request, and I am not able to transfer the TCP data received using the AT command after the TCP connection has been disconnected.
Yesterday I finally got a state machine based serial interface written in Python working. The input to the Python script is a state machine description written in a YAML file.
Here is the script:
And here is a very simple YAML state machine file for the boot up sequence:
Coding up something equivalent for the Arduino will be a pain.
If you install the free 64bit edition of ActiveState Python you will not be able to use pypm to download the pyserial package, as also listed here:
It works fine with the 32bit edition though. It seems like the 64bit editions of some packages are only available to customers with business licenses.
