getAddress return the first address available even if not found the device

[NilsRo]

I prepared 3 sensors but only 1 is connected. A call to getAddress is false but the last address found is written to the variable given.

There should be no explicit address returned if the device is not found.

Reproduction: Call a device number that is not available with at least one device connected.

Can you post a minimal sketch that shows the problem?

The image just does not give information about the content of the variables before your call.

e.g initialize the address with all 0xFF before any call.

Attached a simple sketch.
