GPS/GPRS/GSM Module V3.0 (SKU:TEL0051) SIM and Online Connection
csmith04 2013-05-14 14:00:10 5738 Views8 Replies It would appear that the current wiki for the GPS/GPRS/GSM Module V3.0 (SKU:TEL0051). Only covers GPS and GSM functions, not including how to use a SIM card with it.
I am having a very difficult time finding any information in regards to this.
I've tried the Arduino([url=http://arduino.cc/en/Guide/ArduinoGSMShield#toc4]http://arduino.cc/en/Guide/ArduinoGSMShield#toc4[/url])shield tutorial(and it's appropriate examples). But that is not the same as the current one talked about here.
So my question is this.
Is there any such documentation, code snipits, libraries, API or examples. In regards to the SIM slot and how to connect online through the SIM card?
Thank you for the help!

2013-05-20 21:04:15 Hi Csmith04,
The chip seems not to support HSPA spectrum, I believe I got the same problem with my provider.. I will keep an eye on this and will try other provider (i think they do support it).
Every provider has their spectrum.. I think they should offer support for all those people with GSM phone..
GPRS is a no go with your provider?
About your other questions, this module is driver by AT commands. You can set this commands on your Arduino code easily. Tho I always run the commands stand alone and move them one by one to Arduino. Quite often using a software serial to help debugging.. Jose

Jose 2013-05-18 09:35:40 Ok so I found out from my provider that they run strictly on the HSPA protocol. They use 850,900,1800,1900MHz frequencies but they don't support GSM as they say it is becoming obsolete.
From this, I would either suspect I can not use the device with their SIM card, or Jose, do you know if it is possible to change it(the GPS/GPRS/GSM Module) over to the HSPA spectrum?
Thanks, csmith04

csmith04 2013-05-18 06:08:49 Hi Jose,
I'm in the process of finding out the frequency settings. I am not able to send a message or dial a **.
If I find that the frequency and such is different, am I able to reconfigure some of the code to match it? Or is it based on the device?
Thanks, csmith04

csmith04 2013-05-17 20:59:10 Howdy,
Is your provider using EGSM 900MHz/DCS 1800MHz and GSM850 MHz/PCS 1900MHz? or perhaps some other custom frequency?
Did you manage to send a message or make phone call? It could be that your provider has a different frequency or protocol for the TCP/UDP connection.
Best,
Jose Jose

Jose 2013-05-16 06:13:03 Hi Jose,
Thanks for the reply, I did notice that section later and had tried it as well. But I have ran into some strange issues with that as well.
I am able to connect to the SIM canrd and the device, but when I go to the diagnostics tab and check the connection status and registration status I get the following:
[code]
AT+CGACT?
+CGACT: 1,0
+CGACT: 3,0
OK
Device is NOT connected.
AT+CREG?
+CREG: 2,0
OK
The device is not registered and is currently NOT searching for a new operator to which to register.
[/code]
The strange part is, I can easily use that SIM card with my smart hub. So my SIM is registered to a provider and I have a plan for it.
When I try the TCP/UDP tab and try to connect(after entering the appropriate APN information of my provider) I get the following:
[code]
Checking registration status...
AT+CREG?
+CREG: 2,0
OK
The device is not registered and is currently NOT searching for a new operator to which to register.
Cannot connect without device being registered
[/code]
Is there specific SIM card specs that this device works with?
As well, does this device work strictly off of AT commands?
Thank you for the help csmith04

csmith04 2013-05-16 02:06:38 Hi,
M2Msupport has made a nice testing tool for this board, i suggest you try it. Its looking really good and a TCP example is provided at the end of the wiki page:
[url=https://www.dfrobot.com/wiki/index.php/GPS/GPRS/GSM_Module_V3.0_(SKU:TEL0051)#How_to_drive_the_GPS_Mode_via_Arduino_board]https://www.dfrobot.com/wiki/index.php/GPS/GPRS/GSM_Module_V3.0_(SKU:TEL0051)#How_to_drive_the_GPS_Mode_via_Arduino_board[/url]
I think that would help you to do some 3G data transmission, i hope it helps..
let me know what you think Jose

Jose 2013-05-15 06:04:41 So you are saying by using the wiki page I can figure out how to connect to a server and upload data to it? I don't want to use it for phone purposes. I want to use it to access the 3G/4G services of my provider so that I may upload data that the Arduino collects to a server.

csmith04 2013-05-15 00:08:05 Hi
Here is a picture about how to plug the SIM card . If you use the GSM mode, you need to use a SIM card & you can try the sample code in the wiki, no need library.
