GiovanniDeRosa1 · 2024-11-15T16:11:09Z

Hi, i am using an a7670E module and want to connect to the network and use mqtt to post/submit topics. however, i do not understand if i am actually connected to the network. The status led is blinking very fast

The above indicates that it has been properly registered in the GSM network.

AT+NETOPEN
OK
+NETOPEN: 0

This indicates that the network has been opened normally

AT+CPING="www.google.com" is incorrectly used. You must specify whether the address type is IPV4. The correct one is

AT+CPING="www.google.com" ,1

GiovanniDeRosa1 · 2024-11-18T11:19:57Z

The connection to the network seems ok, now I want to try connecting to the mqtt broker. it is a secure connection but does not require checking the certificate (at least on the esp-wifi side), the connection attempt returns ok, but with an error.

lewisxhe · 2024-11-20T01:03:27Z

Port 8883 needs to be encrypted to use encrypted transmission, please check the provided example operation.
https://github.com/Xinyuan-LilyGO/LilyGO-T-A76XX/blob/main/examples/MqttsBuiltlnEMQX/MqttsBuiltlnEMQX.ino

GiovanniDeRosa1 · 2024-11-20T08:27:59Z

Hi, I am currently using the Esp-Idf framework so without arduino and the example is not of much help to me. Is it possible to know the correct AT command sequence ?

lewisxhe · 2024-11-20T08:34:25Z

You can open

LilyGO-T-A76XX/examples/MqttsBuiltlnEMQX/MqttsBuiltlnEMQX.ino

Line 15 in 01925ec

#define DUMP_AT_COMMANDS

to print all interaction logs

GiovanniDeRosa1 · 2024-11-20T08:52:39Z

ok, but from the example i don't see user and pass. for my broker ( mqtts) it is necessary to enable ssl ( the certificate is not necessary), but i have to report user and pass to access the command ‘ AT+CMQTTCONNECT=1, “tcp://xxxxx.ddns.net:8883”,120,0, “user”, “password”’ is correct ?

lewisxhe · 2024-11-20T08:56:25Z

https://github.com/Xinyuan-LilyGO/LilyGO-T-A76XX/blob/main/examples/MqttsBuiltlnAuth/MqttsBuiltlnAuth.ino
This example matches your description

GiovanniDeRosa1 · 2024-11-22T09:35:15Z

unfortunately i cannot use the example provided with arduino for my c application with esp.idf, is it possible to get support on the commands to use and the correct formatting ?

lewisxhe · 2024-11-22T14:08:23Z

If you run the example you get all the interactions, don't you want to or can't you? I can only run it again and submit it to you, hopefully you can figure it out.

I used an example borker without user and pass, and actually managed to publish,
however if i use my broker with user and pass i get ’

lewisxhe · 2024-11-22T14:17:11Z

Are you testing the same server?

GiovanniDeRosa1 · 2024-11-22T14:20:21Z

yes if I use the mqtt side esp32 configured in this way everything works correctly

Is the firmware version you are using the latest one? Send AT+SIMCOMATI to check
Can you provide me with a test account to test it?
If you are using the latest version and cannot provide me with a test account, then you need to provide the modem log, and I need to submit the log to SIMCOM for analysis. How to capture logs and upgrade please see here

https://github.com/Xinyuan-LilyGO/LilyGO-T-A76XX/blob/main/docs/update_fw.md

do you need broker,user,pass and code id ?

Thanks for the support

GiovanniDeRosa1 · 2024-11-25T08:57:43Z

however i have a doubt on the network side. now i am using my sim (whose apn i know). but i would like to make it so that i can use any sim. is there a way to set up the apn independently?

lewisxhe · 2024-11-25T09:03:37Z

See

I am carrying out tests by not selecting the apn

is this advisable ? i am seeing that 3/5 connects

no, this is the version of this board (without gps)

Confirm again whether it is as shown in the figure below? The new version (A7670M7_B07V01_240927) GPS is invalid, and the old version (A7670M7_B01V01_240105) is valid?

GiovanniDeRosa1 · 2024-11-28T09:14:58Z

yes, and I would add with the same AT commands and configuration. version A7670M7_B07V01_240927 works on the MQTT side
while version A7670M7_B01V01_240105 does NOT work on the MQTT side

lewisxhe · 2024-11-28T09:15:14Z

Are you using the firmware and writing tools I provided?

lewisxhe · 2024-11-28T09:19:19Z

OK, I don't have this module. I will try it when I get it tomorrow and reply to you then.

GiovanniDeRosa1 · 2024-11-28T09:20:52Z

in the meanwhile, can I get version A7670M7_B01V01_240105 so that I can upload it to the module and test whether it actually works on the gnss side ?

GiovanniDeRosa1 · 2024-11-28T09:38:29Z

I cannot load this version, it gets stuck (see screen)

I have tried reloading the latest version (A7670M7_B07V01_240927) and this one loads correctly

lewisxhe · 2024-11-28T09:40:24Z

That'll have to wait until tomorrow.

GiovanniDeRosa1 · 2024-11-28T10:46:22Z

I cannot load this version, it gets stuck (see screen)

I have tried reloading the latest version (A7670M7_B07V01_240927) and this one loads correctly

I finally managed to downgrade the firmware and the gnss part works correctly

lewisxhe · 2024-11-29T00:57:59Z

So the GPS should work fine with the old version, right? I will test it when I get the board.

lewisxhe · 2024-11-29T02:33:37Z

I used the same PN version to test, B01, B07 can be positioned normally

So the GPS should work fine with the old version, right? I will test it when I get the board.

yes, it immediately connects and works normally, I try reloading the new firmware and place the module in the same position

lewisxhe · 2024-11-29T08:23:46Z

Did you re-flash the new version?

GiovanniDeRosa1 · 2024-11-29T08:24:06Z

Did you re-flash the new version?

yes i do

lewisxhe · 2024-11-29T08:25:03Z

Well, surprising

GiovanniDeRosa1 · 2024-11-29T08:26:58Z

and I am currently using your same commands AT
AT+CGDRT=4,1
AT+CGSETV=4,0
AT+CGNSSPWR=1
AT+CGNSSIPR=115200
AT+CGNSSINFO (looping every x seconds if it doesn't read anything)

after 10 minutes he found the position

lewisxhe · 2024-11-29T08:28:18Z

I was outside for about a minute and he was able to find a spot.

GiovanniDeRosa1 · 2024-11-29T08:31:11Z

these commands I am not currently using, are they necessary?
AT+CGPSCOLD
AT+CGNSSTST=1
AT+CGNSSNMEA=1,1,1,1,1,1,1,1
AT+CGNSSPORTSWITCH=0,1

lewisxhe · 2024-11-29T08:32:09Z

This is not necessary, it is used for debugging
