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!

Hi xthuan, OK, There are 2 lights: One that is steady red (pwr?) one that is blue and flashes approx. every 3 sec. What do they show? The blue light was at a time flashing rather fast. torben

HebaIbrahemX commented 5 years ago

so the gsm model which is paining me is on the picture

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 ?

The red light indicates the power, and blue light stands for mainly for connecting actions -- e.g., finding network, sending data, etc.

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?. torben

Normally should be MCU_Tx - GSM_URx & MCU_Rx - GSM_UTx.

HebaIbrahemX commented 5 years ago

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 commented 5 years ago

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

xleray commented 5 years ago

Thanks all you Guys for this great info and Help

belalmc commented 5 years ago

@xthuan GA6-B chip is not the same as GA6 Chip, GA6: RDA88X9CL
GA6-B : RDA8955L

Hai, i tried to flash my IOT-GA6 using that Ai thinker tools but no port detected... i used the old tools and the new one, its just same... no port detected but in device manager my port actually detected ... and i can send AT command 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

nick4o commented 5 years ago

Thanks very much

I’m giving up as well.

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

nick4o commented 5 years ago

Thanks I’ll try

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.

nick4o commented 5 years ago

Unfortunately not a luck at all. I gave up. Bought this it works in UK without need of update.

latheefth commented 4 years ago

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?

SRGDamia1 commented 4 years ago

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

Cale-Torino commented 4 years ago

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.

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

Hi Cale-Torino, Very interesting. I hope this can help with a project I've put aside and get it up and running. Thank you for sharing

latheefth commented 4 years ago

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.

latheefth commented 4 years ago

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.

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
