AI-thihker A6 GPRS /GSM Module

What is GPRS Module?

This is a GPRS/GSM shield with a Quad-band GSM/GPRS engine works on frequencies EGSM 900MHz/DCS 1800MHz and GSM850 MHz/PCS 1900MHz. It also supports GPS technology for satellite navigation. It's possible for your robot and control system to send messages and use the GSM network.
It is controlled via AT commands(GSM07.07 ,07.05 and SIMCOM enhanced AT Commands). And the design of this shield allows you to drive the GSM & GPS function directly with the computer and the Arduino Board. It includes a high-gain SMD antenna for GPS & GSM.

A6 GPRS/GSM Module Description 

A6 Quad-band GPRS/GSM module, is one of the smallest cutting-edge products in the world.It adopts LCC package technology and offers the highest reliability and robustness.Depending on the ultra tiny configuration of 22.8×16.8×2.5mm and easier soldering process, it is capable of being embedded in almost all customer applications.
Featuring an industrial-standard interface, A6 delivers GSM/GPRS performance for SMS, Data and Voice with extremely low power consumption and extended temperature.Extraordinarily compact size and integrated protocols ensure A6 easily meet the requirements of all M2M applications, including VTS, Industrial PDA, Personal Tracking,Wireless POS, Smart Metering and many other M2M applications.

    I am using A7 module from Ai Thinker for GPRS and GPS. However, what I notice is that, 1. The A7 module does not lock GPS 2. When the GPS application on Android Phone shows 13 detected GPS satellites, the A7 module struggles to detect even 3. The best I have seen so far is 4 satellite. But it did not lock the GPS.

    I took the module in open area and kept it ON for 15 to 20 mins without any luck.

    I used commands like AT+GPS=1 and AT+AGPS=1 to enable GPS. Am I missing something here. Any help in this regards would be useful. Regards, Amol

      Hello Amol, did you manage to solve your problem? May I know are you connecting the A7 module to Arduino or straight away to the computer to program it?

      There is no http service ... read the datasheet. You need to make your own HTTP processor . It is not hard. HTTP is very simple.

    Hi i have the A7 and i try to enable AGPS,
    even if i do AT+AGPS=1
    The AT+AGPS=1 always gives me an error message, and from what I have seen in the net, I think that some other code should be executed before the AT+AGPS=1, so it can connect to agps.

    Do you have any idea what i should do to work this around?

    hi.I am using A7 module. so far I can send, receive messages without any problem.when try to check the pre-paid account balance using USSD commands the module returns some weird characters as shown below.

    AT+CUSD=1,"*100#",15



    OK

    +CUSD: 2, "Ùw] ‡Ùa÷¸ ’Î] 

    ç²Ý@ {šÍ •ñð´¼ z»A1Ü+ {É`±›k f³AÕi d †Ýar d~ËAêúœ ’Î]1 ¼, µÓî:½ì QMCP gçA" ,15

    I tried CSCS commands too but it didn't help.Then use same sim card with sim 808 and sim 800 modules and they were able to show expected readable message.I really need you help to solve this problem. My whole project is stuck because of this issue.

      Please try:

      AT+CSCS="HEX"

      Then when you execute:

      AT+CUSD=1,"*100#",15

      you will get the response in PDU hex format.

      I did as you said and this is what I saw on the serial monitor.
      OK

      AT+CSCS="HEX"



      OK

      AT+CUSD=1,"*100#",15



      OK

      according to the http://www.smartposition.nl/resources/sms_pdu.html#PDU the message I received is not even in sms pdu mode.

      Anyway I just want to know if there is a way to convert this message with in the A7 chip. Because I have to send this message in text form to mobile phone.

      Thank you

      So what you've been received are:

      "Your balance Rs. 147.22 will expire on 18/10/2017.Dial 333 to Play Quiz &win Valuable gifts. T&C apply"

      Please email me at zul_nasibu@google.com if you want the Arduino (c++) code to decode PDU hex text to readable message...

  20. Unknown2018年6月20日 07:33

    I updated the firmware on mine, to V03.06, with the links found on this page: http://wiki.ai-thinker.com/gprs/firmware , this page: http://wiki.ai-thinker.com/gprs_download and a little help from Google Translate, but now I can't get the module to accept any input (the characters I type aren't echoed back to me).
    I also tried to downgrade to V03.03 (also available on the site) but still had the same problem.
    I still see the "INIT" and startup messages (I have a USB to TTL cable) but there is no way to enter any AT commands any more.
    In the end, the firmware upgrade was a step back and now I don't have the original firmware (V03.05) to roll-back the upgrade. (sigh)
