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.

The Ping component implements a ping service utilizing the ICMPv6 protocol. It can send ICMPv6 packets, receive corresponding responses, and calculate round-trip latency.

Applications can emit a single ping packet using the sl_wisun_ping_request() API. To receive the pong response, the sl_wisun_ping_response() API is called. The sl_wisun_ping() function offers a straightforward solution for periodic ping packet transmission and reception. To halt the process, use the sl_wisun_ping_stop() function.

Ping test parameters such as size, number of pings sent, and timeout for response absence are configurable. Initialization of the component is done by calling the sl_wisun_ping_init() function.
