Bridge - Device available?

Hello,

Using the bridge functionality, what happens if the other device is offline? How can I check that it’s online before communicating?

I suppose that I can make a simple “keep-alive” mechanism between the 2 devices, but I was wondering if something already exists natively.

Or maybe there’s a way to tell if a command has been sent successfully or not?

Thank you.

The command always gets sent to the server… if the receiving device is offline at the time, then I guess you could try Blynk.syncVirtual(vPin) when it reconnects.
