Hi,

I have problem of error 715 with the example HttpsBuildInGet.
It's work on some site (https://www.google.fr) but not on other (https://hglight.fr/ilo/).

It's not a SIM Card credit issue.

@lewisxhe After upgrade, device registered to network but can't connect, I receive a lot of :
+CGEV: ME PDN DEACT 1
+CGEV: ME PDN DEACT 1
+CGEV: EPS PDN ACT 1
+CGEV: NW PDN DEACT 1

Any ideas ?

It looks like you are roaming. Are you sure this card can access the network when roaming? Have you tried a non-roaming SIM card?

@worldhugo
Copy link
Author

yes, I'm sure, because it worked before the update.

I use sim cards from Whereversim and they say :
The M2M SIM cards of the wherever SIM are pure roaming cards without a home network. This means that these cards exchange data both nationally and internationally via roaming. It is therefore imperative that the roaming option is activated in your end device. Please check whether this is the case. Activate it if it should be deactivated.

Thx,

SIMCOM replied that no additional commands are needed to enable data connection. You'd better try to change a SIM card to test.

If the same situation still occurs after the change, you need to provide the modem log for further analysis.

How to capture the log, please see here:
https://github.com/Xinyuan-LilyGO/LilyGO-T-A76XX/blob/main/docs/a7670x_capture_log.md

I tried with 3 SIM cards ....

Of course, now we just need to wait, which may take a long time.

By the way, you need to provide me with the PN number on the modem label.

Can you confirm that the APN you are using is correct?

Before the firmware update, you can use this APN to access the network and visit normally?

Did the problem occur after the upgrade?

yes, APN is "wsim"

but I don't know why there are Chinese characters or "?"

you can see my code and Arduino Logs in previous comment : https://github.com/Xinyuan-LilyGO/LilyGO-T-A76XX/issues/186#issuecomment-2517745900

Before the firmware upgrade I can use this APN to access the network and visit normally, I confirm !
It's appear right after upgrade

@worldhugo Try this firmware, if it doesn't work, go ahead and capture a log file and send it here. 20241210-A7670E-LASE-TEST

Great, I will give feedback to SIMCOM and there will be a formal version of the firmware later.
