result = handle:ttnBuzz(tid)

## DESCRIPTION

The buzz command instructs the device to cause some attention grabbing activity.

The idea is to have a way to find a specific device among several similar devices.

## RETURN VALUE

On success, returns true. On failure, returns nil. In case of an error, the error can be retrieved using rawio:lastError().
