Bluetooth twig modules have same address!

Hi there

I’ve bought a few of these bluetooth twig devices to use in a project where I need to use a few of them at the same time.

It appears as though they all actually have the same address:

Is there a reason for this? It was my understanding that all bluetooth modules should have a unique identifier similar to the way that MAC addresses work.

If this is not the case, is there a way to set this address manually?

Basically this is a show-stopper situation for the project if we can’t find a way around it!

Many thanks in advance for any advice…
