Im testing my Shield since a few weeks ago and i found problems trying to make a conection http to my page's project with GET.
Firstly i used the code provided on the github for the Arduino (https://github.com/DFRobot/GPS-GPRS-GSM ... RS_GPS.ino), and works for calling and SMS but not to make a conection to my site and i didnt see the error.
So i used the terminal and entered step by step AT commands and the error was not clear for me.
Then i used module tester (http://m2msupport.net/m2msupport/module-tester/), and i received different errors. The first one and the most common to me was an error opening the bearer profiles (AT+SAPBR=1,1). The second one it get ok with the bearer profile and pass to query and gives an IP but on the AT+HTTPINIT get error, and i also tried the calling and SMS and it works perfectly.
The first is the most recurrent.
Im using an Arduino UNO with AC/DC adapter +12V and 1.0A, and obviously the shield on the arduino.
I upload, also, the log received on my last teste with this issues.
Code: Select all
Found ports :COM6



No port is connected.

when i used the 100F/2.7V supercapacitor i applied 2.5v to a single super capacitor and in 30 seconds it only charged .7v but in the introduction it said 30 second recharging time to power arduino if two are wired in a series. Would i need to wire two in a series to get those results?

Hi chi1consulting,

Welcome.

Sorry, is your question related to GPS/GPRS/GSM Shield?
What's the product you mean which has the introduction, "in the introduction it said 30 second recharging time to power arduino if two are wired in a series." ?
