ARP and UDP

[nivek88]

Hi there,
i've been using this plugin within my homebridge for a while. During the last days I recognized that a push on the dash button isn't shown in the Home app (pop-up of the "switch") or any other app anymore and therefore no action can be executed.
While resetting my rPi and re-installing homebridge i've recognized that all of my dash buttons are only sending via udp protocol now. In the beginning respectively during the very first setup of the buttons they send via udp and arp.
Besides homebridge there are two python scripts running on my system, sniffing for the my other dash buttons. These scripts are logging any registration via udp protocol and execute some Sonos/SoCos commands if the buttons are pressed. These scripts still work probably while the homebridge-amazondash plugin does not.
Does Amazon change the communication protocol of the buttons when they recognize, that these buttons are used for another task? And for which protocol is the amazondash plugin sniffing?
