Does the 9160 support TCP protocol(JiMi)

[helen]

Hi

       Customer wants to use TCP protocol and their own packet format to communicate with their own server. Is there any reference example?

Hello,

there aren't any samples that are up to date that I'm aware of. This TCP sample is the best I could find, but it will at least need a few modifications to make it work.

Also, the UDP sample in the SDK is also worth looking at.

Hi

        Thank you for your sample.

        By the way,If the server wants to send data to nrf9160, how does the server know the IP and port number of nrf9160?

Do you want to host the server on the nrf9160 and send to another nrf9160? You can usually tell from the IP header the IP address and port of the sender.
