Hi @jpm ,  
This is the beacon discovery stuff that lets Firestorm discover PBs and synchronize them (or between a PB in AP mode as well). It’s pretty small, but goes out once a second. These can’t be disabled currently. It is only broadcast locally, so its not going out to the internet or something or impacting your internet service / bandwidth.

This was recently [asked about here](https://forum.electromage.com/t/pb-sending-udp-packets-to-255-255-255-255-1889/1451) too. Some [more info on Wikipedia](https://en.wikipedia.org/wiki/Broadcast_address).

These are 12 bytes, 40 if you count UDP frame overhead. 36 days is a bit over 3 million seconds, and the math gets close to your 126MB figure. Put another way, it’s ~0.0003 Mbits/sec of bandwidth.
