V1.6.0-rc2 SDK is released on 12th june. Does this version provides examples and limplementation required for non-ip based Apllications? or We need to wait for V1.6.0 release?

Thank you\

Hi, yes, it's most likely included in NCS v1.6.0-rc2 for you to test. Please note that it may be unstable or not fully implemented. 

Please give it a go and let me know how it works for you.

Kind regards,
Øyvind

Now iam using V1.6.0.  Able create PDN Context and associted PDN ID successfully using the API provided by APN Library.

Raw Socket creation is successful but bind is failing.

PDN Context = 0 and PDN ID = 0 after creation for NONIP Family.

sock_nidd = socket(AF_PACKET,SOCK_RAW,0);  // Assuming success as sock_nidd is not -1.

pdn_str[0] = (0 +48);  pdn_str[1] = 0;     length is 1

err = nrf_setsockopt(sock_nidd,NRF_SOL_SOCKET,NRF_SO_BINDTODEVICE,(void *)                                                                                                                                              pdn_str,strlen(pdn_str));

Failed to bind the nidd socket to PDN ID

Thanks

Hello, 

Unfortunately, our modem team is currently on vacation. I'm not able to provide any other answer at this moment.

Have you tried the same using the Modem Shell sample? Or looked at the PDN sample?

#create and activate context (note: activation fails if not supported by the network)
mosh:~$ link connect -a "nonip.apn" -f "non-ip"
PDN event: PDP context 1 activated
Created and activated a new PDP context: CID 1, PDN ID 1
#create a packet/raw socket and bind to created PDN context
mosh:~$ sock connect -f packet -t raw --cid 1
Socket open and connect family=3, type=3, port=0, bind_port=0, pdn_cid=1, address=
Socket created socket_id=0, fd=4
#send data to a created socket
mosh:~$ sock send -d foodata -i 0
Socket data send:
        foodata
RRC mode: Connected
mosh:~$

mosh:~$ link funmode --pwroff
Network registration status: not registered
mosh:~$ link defcont -e -a "non-ip.apn" -f "non-ip"
link defcont enabled
mosh:~$ link funmode --normal
Functional mode set successfully: normal
Network registration status: Connected - home network
etc etc
mosh:~$ sock connect -f packet -t raw
Socket open and connect family=3, type=3, port=0, bind_port=0, pdn_cid=0, address=
Socket created socket_id=0, fd=4
mosh:~$ sock send -d foodata2 -i 0
Socket data send:
        foodata2
RRC mode: Connected
RRC mode: Idle
mosh:~$

Kind regards,
Øyvind
