nRF9160 ping event with AWS IoT

[ksksue]

How does the device catch incoming ping events?

The device uses AWS IoT library, so it can't open a raw socket.

It looks like the ping events closed inside the modem binary.

So, this code does not run.

/opt/nordic/ncs/v2.0.2/zephyr/subsys/net/ip/icmpv4.c

Are there any ping event APIs? or sniffing raw packets?

Hello,

 

Thank you so much for your patience.

 

When opening a SOCK_RAW type socket, there's restrictions that apply. Mainly, you have two options:

* Open the SOCK_RAW on a dedicated PDN

or:

* Keep all other sockets closed while the raw socket (SOCK_RAW type) is open.

 

My apologies that these undocumented restrictions apply to this type of socket.

 

Kind regards,

Håkon

Thank you for your consideration.
Having seen your post, this is my understanding:

• Ping events from the server are typically processed within the modem firmware, and the application side cannot catch these events.
• Ping events from the server can be captured by opening a raw socket. However, it is not possible to simultaneously capture events with AWS IoT and pings from the server.
