Listener losing positioning

I’m using a listener to receive the tag positioning.
When I initialize the listener all notifications are received in all afected area.
After a few weeks or even days, the listener is only able to receive notifications of the closest tags losing data from more distant tags inside of afected area.
Has anyone experienced this problem?

Best regards

Hi Tiago,

Are you sure that the further devices are still transmitting ?

There is no reason why a Listener would lose some sensitivity over time and not be able to receive frames it could initially receive.

Kind regards

Hi Yves,
I replace the listener, and the problem was solved, it was a hardware problem.

Thanks for you reply.
Best regards
