PING service API

Detailed Description

The PING service is used to test if a system can communicate over the network with another device or computer.
It operates by sending Internet Control Message Protocol (ICMPv4/v6) Echo Request messages to the destination device and waiting for a response.
After the PING service is initialized the fnet_ping_init() function, the user application should call the main service-polling function fnet_service_poll() periodically in background.
When correct echo response is received, the PING service passes an echo-reply socket address to the fnet_ping_callback_t callback function.
For the PING service usage example, refer to the FNET Shell demo source code.

Note

The PING service uses the RAW sockets.
