Connecting to HTTP fail

[Juatmann]

I have a TTGO Tcall V1.3 board. I filled APN data and uploaded your code.

Wifi AP is created, then I connect with my phone but says (no internet connection)

Here you have the serial monitor:

Hello Juatmann, nice that you have found my code.
First your code is fine and will work, if you enter in the Browser something like:
http://192.168.4.1:8083/vsh.pp.ua/TinyGSM/logo.txt
Perhaps my documentation is not detailed enough. If you are fine with the hint we can close the issue. Regards SFeli

Hello SFeli. Thanks for your response.

I have checked your advice and it does not work. I have congured my wifi adapter in 2 ways:
1-Static IP 192.168.4.100. Did not work
2- DHCP IP: Did not work

Here is the log:

Now I am trying to modify your code to get internet connection without needing to enter that address in Browser. I want to get internet only with power on the board.

Could you let me know how to modify it?

Thanks for your support

Hello and sorry for the late response,
the board has a GPRS on board and opens an own WLAN - Accesspoint.
You have to connect to this network (name should be "T-Call" with your PC or mobile device.
Once you are connected you should open the browser and request the following webpage:
http://192.168.4.1:8083/vsh.pp.ua/TinyGSM/logo.txt
then the request will be passed over the WLAN to the AP on the ESP32 and forwarded to the GPRS into the Internet. You should receive an answer from the internet the same way back.
The program will not search for index.html or index.php you have to request for the object itself. Like the logo.txt on the folder ThinyGSM
Hope you will have success with this detailed description. I think you expect more than available.
Regards
Stefan
Pls. Close the issue if understood

Hello,
I happen to have same problem as him, my hotspost seems to be working just fine, only problem is that when I type on the browser of the connected device to do the call it just gives me nothing and says the page doesn't work also the device tells me (No internet) on wifi settings, the code I used is very similar to yours just changed a few lines, I am using a T-Call v 1.4 board with a SIM800H paired with a thingsmobile SIM . I have tried also an example that does directly calls from esp32 (but no hotspot) and that works. also I think the problem here might be that i get this: Modemstatus: 1 which I understand it means no internet from the module. Does any of you have a solution by any chance? thanks in advance.

Kind Regards
