Hola es posisble conectarse con varios antenas o varios moviles ?

Funciona de coordinador zigbee y se conecta a los dispositivos de este tipo y a otros hubs zigbee de tu red. Debe estar conectado a un PC para gestionar los dispositivos.

is there a commitment that this is upgradeable to support the thread standard
