That's pretty terrible of Roku.
So apparently the Switch (via Pokémon Sword/Shield) is sending out probes to try and find other switches connected to the network (for local communication probably), along with the standard bluetooth probes it does. Select Rokus do not like being randomly probed/data being flung at them, and start bootlooping as a result.
It is almost like Roku engineers forgot that other devices can send BT packets as well
Wow this is pretty bad. What part of dropping the packet in the worst case is hard ?
There’s another comment that claims it’s the fact the switch is trying to pair constantly with it (which doesn’t sound right, I’ve been doing some BT dev here and I haven’t had my switch trying to pair even though I’m playing at the same time). Regardless, good job Roku either way I guess.
It sounds like the affected Roku doesn't sanitize the bluetooth input and/or incorrectly trusts a bluetooth connection with a certain formatting. Yikes.
Yes, but it's also ridiculous to have the Switch spam IPs in the space like that. Boo on both of them.
Broadcast for service discovery is totally fine.
