Ping#

The Ping component implements a ping service based on the ICMPv6 protocol. The component sends ICMPv6 packets, receives the associated responses, and computes the round-trip latency. Using the sl_wisun_ping_request() API, an application emits a single ping packet. To receive the pong response, the application can then call the sl_wisun_ping_response() API.

The sl_wisun_ping() function provides a simple solution to periodically send and receive ping packets. To stop the process, call the sl_wisun_ping_stop() function. A ping test is configurable in size, number of pings sent, and timeout if a response is not received. Ping service supports multicast group addresses, where multiple response can be received from different addresses.

To initialize the component, call sl_wisun_ping_init() function.
