Ping session

In order to evaluate the reliability of a communication between two or more devices, a Ping

session can be performed. A ping session consists of a Master sending a sequence of

messages to one or more Slaves. If the messages are correctly received by Slaves, they are

re-sent to the Master with the same electrical parameters and Payload data, enabling the

application to collect statistical data.

When a Ping session is active, the GUI adds some automatic services to the functions and

commands of the ST7580 device.

The Ping tab displays different control and indicator values in accordance with the role that

the EVALKITST7580 board, handled by the GUI, has during the Ping session.

Figure 22 shows both Ping tabs for Master and Slave nodes:
