A6 GSM GPRS Module From AI Thinker






A6 AI GSM Module - My Electronics Lab

After ESP8266 , which broke all the market records in IOT, providing the cheapest WIFI chip in the market, Now AI Thinker seems to be promising with a new module in the market, I.E  A6 GSM/GPRS Module at only  $3.6.  All Alibaba and Aliexpress (leading Chinese online seller) are fully loaded with this module. This A6 GSM/GPRS Module Seems like, A big competitor for SIM900 series module.

These modules coming  in market SMT package, as ESP12E, But there are many vendors already making breakout board with antenna out and SIM card slot, for an extra dollar.

Alibaba sellers are claiming, this is the smallest available Industrial grade quad-band GSM / GPRS module.

Features that Make difference:

  • Competitive price!
  • Compact size, 22.8√ó16.8√ó2.5mm
  • Easy to use DTU
  • Industrial level GPRS
  • Can use SMS to config module
  • Support up to 8 channels network connections
  • Low power consumption: standby least is 3mA
  • Wide operating temperature range
  • A6 semi-hole technology, enabling rapid production modules through standard SMT equipment, providing customers with highly reliable connection, especially for automation, large-scale, low-cost modernization of production methods.

  • Nice release! If they open the SDK as they did with ESP8266 will allow developing small and integrated IOT devices.

    • ernie

      There is a BRUTAL CPU inside 32MB flash 64 MB RAM on board . LiIon battery chager , 7 DMAs, but any closer info is confidental ūüôĀ I think they will not open SDK ūüôĀ

  • Germ√°n

    I’ve got one. But there is no information at all about pinout of breakout board module. Do you have any?

  • Uzairali001

    Can we use this module for GPS tracking?

    • My Electronics Lab

      no, You cant, this is GSM modem not GPS

      • Uzairali001

        Is there any cheap alternative then?

        • My Electronics Lab

          NEO6MV2

          • Uzairali001

            Thanks

      • mbenitez01

        USE A7..FROM SAME MANUFACTURER

  • Steven Morehouse

    Any luck getting anywhere with this?

  • yogeshd

    Dont spend money behind this module …its like wasted money ( I did and spend week ) …1. baud rate is fixed to 115200 2. serial communication only work with hardware serial ( now way it will work with software serial for arduino) 3. dont have dns look,http client or server . SIM800L is best alternative has ton of features and has almost same price range.

    • somewhatconfused

      I’ve also just spent hours on this module. I wouldn’t say its a waste of money, just that you should be aware of what you’re getting.
      As for the SIM800, its also has its issues. For example inbuilt HTTP support does not support URL > 64 characters, inbuilt SMTP support does not accept mail addresses with non alpha_numeric characters.
      The list goes on.
      If you find a GSM module for the price of the A6 and with Telegram support that works, please let me know.

        Hi friend,
        Can you let me command which you used to make http post method work, I have searched a lot also contacted a6 team, but no documentation is available which says that http support is there.. can you share example code or something..

          Salutare. Nu inteleg de ce mie nu-mi merge modulul asta cu Arduino Uno.
          L-am conectat cum trebuie, dar vad ca nu face nimic.

          Poti sa-mi dai o idee de ce nu ar pleca? Mersi mult.

          • Maciuc Alexandru

            Dupa multa cautare am gasit ca acest modul nu prea e optimizat sa poata comunica cu un arduino pe seriala. Poate comunica cu un PC printr-un modul USB special, daca ai sa cauti pe youtube vei observa ca marea majoritate folosesc un modul USB. Eu am renuntat la acesta si am achizitionat un SIM800L si merge fara probleme. Pretul nu difera mult intre cele doua.

          • Wildriff

            Am inteles. Deci asta e practic varianta made in china pe vapor :))

            Da, am vazut ca folosesc Serial to USB si se joaca cu el prin serial monitor sau prin vreun terminal pt serialcom.

            Ok. Multam fain pt informatie.

  • Droid Debian

    thanks for the post. it seems there is another version called A7 there, is that a better one?

    A6 and SMS woes
    After playing more with the A6 I’ve notices wierd behaviour when the A6 handles SMS in PDU mode. The AT+CMGL command cannot list messages received in PDU mode, only those in text mode. You can read them (+CMGR) and deleted them (+CMGD) just not list them (+CMGL).
    Anyone else notice this?
    Also the “ME” store for messages does not appear to exist. This makes sense as the A6 probably has no flash memory (keeps it cheap).
    Finally, the documentation lists messages that don’t work (AT+CMGD=0) and omits unsolicited messages that do pop up e.g. +CIEV “Message”.
    As I noted in a previous post – you get what you pay for.

  • Gaurav

    could anyone make HTTP post worked with A6, does A6 module support it ?

    • Xiaohu Jing

      IT WORKS FINE

      • Mark

        I’m also in trouble with http. Mr. Xiaohu Jing can you please help me how to do http get/post using A6/A7 modules?

  • a_r_e_k

    Isn’t GSM expected to be dropped in next 4 years in many networks? And AFAIK this module doesn’t support 3G.

  • Just wondering if we can part this thing out and make something useful out of it.
