bluetooth has plenty of bandwidth, it can stream out data at nearly CD quality, pretty sure bluetooth 5 is over 100mbit
#asknostr I have a request for the hardware / Pi developers out there.
I want to run a small Go or Rust (khatru, haven, rs-nostr-relay, or chorus) based relay on a Raspberry PI, obviously its going to be using web sockets but I want to also connect to it over a USB serial interface like the https://github.com/lnbits/nostr-signing-device
My goal is to build a personal pocket relay that can connected to wifi (and discoverable) or connected via USB to a computer and managed from there.
Bonus points if we could also find a way to talk to it over Bluetooth, although I doubt ble has enough bandwidth

so, bt4 you get 1/3 mbit, 1mbit for 4.2 and 2mbit for 5... so that works out to ... about 56kbit for bt4, 100kbit for bt4.2 and ~ 250kbit for bt5
this is duplex of course, if you have it running alternate simplex it would be twice that
