Setting socket option RAI_NO_DATA gives ERROR

[mnjLC]

Hello Team,

I have have loaded the modem FW  2.0.1 and Serial LTE Modem application on my NRF9151-DK from Quick Start.

I wanted to test the RAI release functionality and cam up with below mentioned at commands

at+cfun=1

At+cereg?

At+cgdcont?

at%rai=1

at#XSOCKET=2,2,0,0

at#XSOCKETOPT=1,61,1 // to imitate instant RRC release 

According to the documentation provided at this link It should initiate the RCC release but the command gives an ERROR. Can you please check it on your side ?

I am on NB-IoT network in India.

Thanks!

Hi,

Can you provide full list of AT commands that you used including the responses?

Below is the full list of AT commands

AT+SSRDA=0,1,1
AT%XSYSTEMMODE=0,1,1,2
at%xbandlock=1,"10000"
at+cfun=1
at+cereg?
at+cgdcont?
at%rai=1
at#XSOCKET=2,2,0,0
at#XSOCKETOPT=1,61,1

We are trying to do this because we want to release RRC in certain corner cases where we do not have any data to send but for some reason RRC connected.

Thanks!

Hi,

nrf_socket.h specifies that the socket needs to be connected.

/** Indicate that the application does not intend to send more data.
 *  This applies immediately and lets the modem exit connected mode more
 *  quickly.
 *
 *  @note This requires the socket to be connected.
 */
#define NRF_RAI_NO_DATA 1

Best regards,
Dejan
