B4R Question If WiFi connection (or Internet connection) is suddently missed ...

[peacemaker]

HI, All

If you use a MCU board sending info to a server, and suddently WiFi connection to a router or the Internet connection of the router is ... out - how is it known for the MCU ?
During HTTP job i guess, it will be Job.ErrorMessage, but if no active requests ?
How to track, check here in the microcontrollers world ?

I have used a "heart beat" for such communication. Simply put ping the server with minimal data every x seconds.
Although not sure if this is a good solution!
