If I load firmvare send "Failed" |
|
I just did it without any problem.
I used a ftdi ttl/rs232 converter with rx to HTX (A6) and tx to HRX(A6)
This is working with the ai thinker tool

I use same ftdi ttl, But issue in open port |
|
This is working perfectly for me.
Do you check that your are able to comunicate to your FTDI adaptater ?

after flashing firmware you need to set the imei !
like that : AT+EGMR=1,7,"998111854633244"
you could check imei after:
AT+EGMR=2,7
if you do not do that imei is 0000000000000 and your networ will not accept
to register the module !

Hi @manuprendlair , thanks for your input. This is valuable, added link to this topic to the README. |
|
I successful flash with another ftdi adapter, but after flashing module don't response on at commands |
|
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. nothing happens |
|
how do you connect the A6 to your computer? you need a serial to usb
converter module.
You need first to check your module ir recognize by your computer (sometime
you need to download driver, but generaly not if you use ftdi converter
module), a new com port must be create.
Sometime the tool not working if you have different com port.
also take care to your connection tx to rx and rx to tx
Generally, problems come from the user and connections, check all two
times, three times!
For myself, I had too much problem to make the A6 working correctly with at
command (gprs connection etc.), so finally I decide to use a sim800 module,
who is a sure value!
Have fun!

Is there a driver i need to install first?
ps: i tried the connection with bost the h-rxd and h-txd as the u-rxd and
u-txd
nothing happens

tnxs i think i'm gonna buy an other one... haha |

this usb serial converter is best : FTDI FT232RL USB to TTL Serial
Converter Adapter Module (google this)
For the gprs, yes I suggest not to spent to much time with the A6 !
have fun
2018-06-05 12:25 GMT+02:00 Gerwin Vis <[email protected]>:
… tnxs
driver for PL2303HXD usb to uart ttl is installed and recognized bij the
computer
and the com port thing you explain is new for me....
i think i'm gonna buy an other one... haha

allright, don't know what i did different but it says it passed. |
|
humm If I well remember on the ai thinker wiki you could find a tool to
test at command.
but I wrote my code with the gps tiny library.
I had no success with the A6, sometine register to the network, sometime
not, sometime return some code nobody know...I just was successful sending
sms and make call two or tree times..but not for gprs connection
let's me know if you have success with it !

i'm a noob in this things... what software do you use to test with at

any tips on the best baud rate? |
|
The baudrate is 115200 for the A6
You could change it, but when reseting the baudrate come back to 115200.
Normally you could use profile to save settings like baudrate. profile must
normally be load at startup... I never been able to make it working on A6!
Good luck and let's me know if you'll have success

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. |
|
To end my story, i stopped trying. Bought a adafruit feather fona. Sorry, its not an answer to your question but i wanted to end my story |
|
so the gsm model which is paining me is on the picture |
|
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: 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. |
|
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. |
|
@yatan are you using software serial? If so, try to set baudrate 9600. Software serial may not be safe for higher baud rate. |
|
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. |
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. --xintao |
|
Hi, |
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 |
|
Also what IDE that i can use (if i'm not using arduino ) ,to configure the module with AT-commands ? |
|
Thanks all you Guys for this great info and Help |
|
@xthuan GA6-B chip is not the same as GA6 Chip, |
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. |
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 |
|
Thanks very much
I’m giving up as well.
Regards
Nik

i used the old tools and the new one, its just same... no port detected
but in device manager my port actually detected ...

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:

VCC
Tanks in advance.

it might sound weird, but it worked for me;
use;
Vcc_in -----------------5v
U_RXD --------------- RX
U_TXD---------------- TX
GND--------------------GND

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 hope this will help someone. #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.
#Example using the Arduino IDE
I have included the code for an example testing_GPRS.cpp in a zip file included. It only uses SoftwareSerial.h |

Hi Cale-Torino, |
|
Hi All, |
|
ATE0 command had to be sent to turn off echo. Now it's ok. |
|
Can anyone help me with iot ga6-b module? |
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: Also since the COVID-19 nonsense I had some time to make a website for small interesting programs and projects etc. 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 |
|
iot ga6 b is a worse model...dont use it...i tried my best...but result no success at all...i buy sim900A now...so who ever read this topic...make it sure that its a bad model....for connecting with arduino uno r3 |
|
Hello. If anyone still has firmware from A6, please share, otherwise all links to the wiki do not work |
|
A6_V03.03.20161229019H03.afw.zip I have this version used on: Jun 2018 |
|
Thanks |
and others
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!
Emmanuel
