LTE-M Release assistance indication (RAI): How to indicate?

[crasspm]

Regarding the new modem command AT%RAI, the documentation here says:

In addition to using the %RAI command, the application must tell when the data connection is not needed anymore through the application domain data socket interface. With the interface, the information can be given with the last data packet that is sent or after the application has received the data packet that ends the need for the connection. Each socket client tells their own need for the connection, and the information is combined in the modem domain.

How is this accomplished?  Is there an example somewhere of how I should get my application to tell when the data connection is not needed anymore through the application domain data socket interface?

Thanks

Hi, I have the same behaviour when I want to use the socket options, but when i close the socket right after sending it gets into rrc idle immediately, but I guess this is not the right way to do it..

Do I have to use nrf_socket.h respectively nrf_socket/nrf_connect/nrf_send when using nrf_setsockopt?

Hi, visu.

Yes, I recommend that you stick with just one socket API at a time.

The two socket APIs might use different numbers for the same socket (Zephyr's API uses the nrf_socket API internally on the nRF9160), as well as different numbers for the same socket options.
