Hello,

This not really an issue but a solution for these who bought IOT-GA6 from GOOUUU TECH.
You could reflash the firmware with the AI-THINKER A6 firmware.
I just do it and confirm this is working!

please look at:

http://wiki.ai-thinker.com

you will find tool and latest A6 firmware
(use google translation if like me you couldn't read chinese!)

Have Fun!

i downloaded the tool and the firmware... opened the tool, connect the oit-ga6 to my computer. My computer tells me it doesn't recognize the usb device and nothing appears in the tool.
Is there a driver i need to install first? (driver for PL2303HXD usb to uart ttl is installed)
ps: i tried the connection with bost the h-rxd and h-txd as the u-rxd and u-txd

nothing happens

Experts Please Help! I can not even connect and run the Goouuu Tech IOT-GA6 module? I am looking literature for this module but all of them are in Chineese, please help me to understand and read about this module in english links, pdfs etc.

I tried a IOT-GA6 module with arduino mega 2650 using Serial1 instead SoftwareSerial

Using arduino for connection between modem and computer worked ok: AT commands worked right, but I got errors when tried GPRS connection sequence.

It failed every time until I found the right sequence:

Instead using

AT+CSTT=”apn”, “”, “”

Use

AT+CGDCONT=1,”IP”,”apn”

Ok, I use an apn without user and password, but it would be nice if anybody could try connection to A6 module and GPRS connection

I've no time for now to modify library and try gprs connection, but it should work.

Worked TinyGSM with Goouuu Tech IOT-GA6.

Updated a Goouuu Tech IOT-GA6 module using a stable oficial A6 firmware using simple usb_ftdi_ttl converter, connecting vcc_in, gnd, rst, h_rxd, h_txd pins and work fine the upgrade.

Upgrade tool:
http://wiki.ai-thinker.com/_media/ai-thinker_gsm_module_download_tool_v11.00.04.7z
Upgrade image:
http://wiki.ai-thinker.com/_media/gprs/a6_v03.03.20161229019h03.rar

Then used a AT_Debug for know the modem COM speed (after upgrade changed to 38400), and upgrade de IMEI with AT commands commented the user: @manuprendlair

Used Diagnostics sketch to test, and work some GET petition to web server, the modem get stuck to recognize the response, but the petition to server are made correctly.

Hola, tengo este módulo y necesito ayuda para un proyecto ya que no estoy muy adentrado en el tema de módulos gsm y gprs. No encuentro nada que explique paso por paso como hacerlo funcionar y por eso acudo acá. Si alguien puede darme una mano estaría muy agradecido. Desde ya muchas gracias.

@GerardoAllende

The only way it worked for me was updating the firmware as @yatan posted but connected FTDI TX pin with the A6 U_TX and the RX with U_RX. This way I can receive the "OK" response from my "AT\r."

@lucianog2000 yo también estoy empezando con este módulo y perdí todo el día probando. En mi perfil está mi dirección de email.

@cbolanos79

@yatan are you using software serial? If so, try to set baudrate 9600. Software serial may not be safe for higher baud rate.

@chaton78
Copy link

Firmware upgrade worked for me... but I had to connect RX to HRX and TX to HTX which is the opposite of what I am used to with Serial Connection. Note that Uart connection is standard on this module (RX->U_TX, TX->U_RX). Don't forget the Ground.

Heeey , i have the same module and i'm at the very early phase of wiring it to the PC to enable communication , have you figured out how ?

A good news is that, your board is the regular GA6 instead of the GA6-B, which means, you can use the aforementioned tutorial to flash the GA6 module to aithinker-A6 firmware.

Hi,
I have to connect hSerOut to U-TXD and hSerIn to U-RXD t make the AT commands work. Is that normal?.

Normally should be MCU_Tx - GSM_URx & MCU_Rx - GSM_UTx.

Helloo, did anyone happen to be using python to send AT-commands to the module through the usb-ttl converter ? if yes what library ? (windows OS) .thanks in advance

@HebaIbrahemX

Also what IDE that i can use (if i'm not using arduino ) ,to configure the module with AT-commands ?
through the usb-ttl .

Hai, i tried to flash my IOT-GA6 using that Ai thinker tools but no port detected...
image
i used the old tools and the new one, its just same... no port detected
but in device manager my port actually detected ...
image
and i can send AT command
image
so i think my port just working fine, but why Ai Thinker tools can't detect my port?
i used FTDI and USB to TTL, and the result is still same... Any Solution?

Hi everyone I'm new with this. Is there solution for this issue? my one is IOT-GA6-B and Ai-thinker can't find the port to communicate with the board.
I'm using the following pins:
HTX
HRX
GND
VCC
Tanks in advance.

Unfortunately still no solution on that. The GA6-B is quite problematic.

you may need to consider using another module like sim800 or sim900. I've done with GA6-B with no solution at all and change to another gsm module

I managed to communicate with mine
it might sound weird, but it worked for me;
use;
Vcc_in -----------------5v
U_RXD --------------- RX
U_TXD---------------- TX
GND--------------------GND
You might require ATCommandTester-master to track the baud

Hi everyone.
Has anyone succeeded with GA6-B? I need to do a project with a GSM chip at 3.3v, already discarding SIM800L and similar boards.
I was testing A6 from Ai-Thinker and it works correctly, but I need the MINI version. My supplier is only able to get this version of GOOUUU TECH and I am afraid that it will not work.

Any success with GA6-B? I get AT OK , SMS Ready, CREG+ 2 then +3 but after 7-8 sec the module restarts with POWER_ON on terminal. Is there any solution? The LEDs dims from it full glow after initial 7-8sec. Any idea how to make it work? Will the 4700UF cap at the Vcc fix it, I read it someone had it fixed that way?

I know nothing about that module, but I know a smooth steady power supply can solve a huge number of issues.

#I have the IOT-GA6-B module like in the photo below

I was struggling to get the TCP connection to work. Eventually I succeeded, here is what I did:

2 big problems are: spaces/whitespaces and newlines.... what a pain....

After sorting those out I was able to get my data sent to a php script I wrote to store the data.

#This picture below shows that the server was receiving the TCP request but formatting was the issue.

#This picture below shows that I can send data to the port using a homemade protocol, however it will take to long to make a whole protocol to "catch" the data. So I scrapped that idea for now.

I have included the code for an example testing_GPRS.cpp in a zip file included. It only uses SoftwareSerial.h

Hi All,
I am using GA6-B with pic16 mcu and I am able to receive the startup cmd from the module but when I reguest AT cmd or any other I don't get any response but echo of my request is seen on GA6 TX pin. I have tried the module on PC directly with FTDI and it respond as expected but not with the pic controller. I also tried using level converter from 3.7v to 3v but doesn't work (capture on TX pin of GA6-B)
Please help if anyone knows about it.

ATE0 command had to be sent to turn off echo. Now it's ok.

Howsit, use this tester ATCommandTester to see if the module is working with the sim card. Connect TX,RX,5V,GND to a device like a FTDI FT232 Micro USB to Serial to communicate via the COM port on the computer. If it's working properly then go to these links below for more info:

forum.arduino.cc

github.com/iotwebplanet

Also since the COVID-19 nonsense I had some time to make a website for small interesting programs and projects etc.
You can check it out at https://tutorials.techrad.co.za

I just add to it sometimes so it's not an official thing yet... maybe in future.

Brother, i have become succesful getting 2 light in the IOT GA6//1 light is full on and the other is blink in every 2 seconds///BUT i dont get any AT commend or response by it...what should i do for getting AT command?????i have try your code ...but not working.... @Cale-Torino
my new connection
Arduino uno <-> IOT GA6_b mini-GSM
5V(direct arduino uno r3) <-> VCC
