Cool stuff! Actually that tempts me to start a new rabbit hole research: could we do BT -> Internet -> BT. I would have so many uses to that.

> could we do BT -> Internet -> BT

Quite probably, though there might be protocol latency issues that you need to be careful of and they might limit the effective range (lookup the “We can't send mail more than 500 miles” tale for a related issue!).

Well, you need a frame converter that sends it to an IP address/DNS server, and on the receiving side something that receives that packet on a specific port and translates it to a BT command.

I would say the most complicated part would be the TCP/IP stack, and binding/publishing your address, but if you are running something with Embedded Linux it is doable :)

ESPHome has this feature (called btproxy). It works well with BTLE devices. I use it for remote temperature sensors and a few other IoT btle devices.

This seems to be specific to Home Assistant:

> Note that while this component is named bluetooth_proxy, only BLE devices (and their Home Assistant integrations) are supported.

One specific use-case I have in mind is controlling a Chromecast over the internet. So a smartphone should have its bluetooth signal relayed over an IP network. I haven’t found anything that would allow me to do that yet.
