WiFi PRO V3 05: Ping

This example shows how to check connectivity to the Access Point and then it performs ping connections to the host address specified as input.

Required materials

1 x Waspmote 1 x Battery 1 x WiFi PRO V3 module

Notes

- The battery has to be connected - This example can be executed in Waspmote v15

Output

H#
Start program
***************************************
It is assumed the module was previously
configured in autoconnect mode.
Once the module is configured with the
AP settings, it attempts to join the AP
automatically once it is powered on
Refer to example 'WIFI_02' to configure
the WiFi module with proper settings
***************************************
1. WiFi switched ON

WiFi is connected OK
Ping sent packets = 3
Ping Received packets = 3
Ping Lost packets = 0
Ping Total Time (ms) = 341
Ping Minimum Time (ms) = 93
Ping Maximum Time (ms) = 153
