HL7692 TCP connection over LTE

Hello,

I am trying to establish End to End TCP Connection using only LTE.
The module is set to connect only to LTE network.
AT Commands Interface Guide.pdf does have only GPRS connection example.

Can anyone help me with this case? What type of AT commands should I use?

Thanks,
Michal

Hi Michal,

You can still use the same KTCP example when using LTE.

Hi,

but should I set LTE parameters (APN, login, password)?
I can not find AT command similar to: AT+KCNXCFG=1,“GPRS”,“APN”,“log”,“password”
Is it possible that you can show me an example?

Michal

Okay I think I get it.

Using the same sequence of commands let you establish internet connection on LTE network. The gsm module ignore “GPRS” label in command: AT+KCNXCFG.
Is my assumption correct?
