SIM5360 don't acces to my server

Hi,

Since I get a Freelatics One+, I try the code sample and config on your github (https://github.com/stanleyhuangyc/Freem ... im5360test)
for made a connectivity test with my M2M card (I have a valid APN), it work well :

But If I change the adress / port it doesn't work anymore :

Error connecting

ERROR


I have try some websites with HTTP POST request like http://XXXX:38080/BEG/freematic/gps

This website have an "Authorization: Basic"

The code stop working on the code :

if (!net.httpConnect()) {
Serial.println("Error connecting");
Serial.println(net.buffer);
errors++;
return;
}

And it's return this error

Error connecting
+CHTTPACT: 227

Do you have any idea how is the problem ?
I have try the commands
- AT+CHTTPSOPSE
- AT+CHTTPACT

But it's not working in https or http

In linux, I'd recommend man in the middle'ing it with socat:

socat -v TCP-LISTEN:38088 ,forever,reuseaddr,fork TCP:http://XXXX:38080

and then change the port that you're accessing the server to 38088. That socat command will show all data flowing back and forth between the client and the server on port 38088.
