#102Thank you, I was looking for something similar years ago and was surprised there wasn't rando product on aliexpress.
Re: Show HN: Bluetooth USB Peripheral Relay – Bridge Bluetooth Devices to USB
#103This solves a huge annoyance I've had: swap a Bluetooth keyboard/mouse between multiple laptops, without manually un0paring / re-pairing. I have a personal "hot desk" at home. I want to be able to plug in any laptop to the large monitor, and have the wireless keyboard/mouse on that desk instantly work. And when I leave the desk with my laptop, I don't want that keyboard/mouse connected anymore. This has been impossib…
Fun & cursed fact, the ArchWiki has a rather long section on dual boot pairing. Pair in Windows or Mac then painstakingly extract various bits of pairing info from the OS and toss it into Linux, so you can dual-boot & keep the pairing. https://wiki.archlinux.org/title/Bluetooth#Dual_boot_pairing
I've always wondered how feasible it would be to copy Bluetooth pairing information. This particular series of hacks seems to rest at least somewhat on it being the same Bluetooth host adapter. (But maybe the host side can spoof, trade IDs with the other device?)
Ideally I'd love to centrally and dynically manage what devices of mine are paired with what system... I think that might be technically feasible, as long as I'm not trying to pair multiple things with a single bt adapter.

All of this is being insanely overcomplicated. Throwing more complexity at a simple problem might be "fun" from a nerd's POV, and, TBH, building this USB device sounds fun. But entirely unneeded while introducing more points of failure. A simple solution to your problem: 1. Get a monitor with a built-in USB hub (nearly all of them?). Consider getting a USB-C monitor to reduce the number of cables to 1. 2. Don't use B…
A cheap USB switch would also work, that would reduce the switching to switching monitor inputs and pressing the button the USB switch
I did this for a while but was a bit annoyed with the delay since it "unplugs" and "plugs" in the mouse/keyboard each time you hit the button. What I ended up doing is buying a used KVM switch with DDM (https://en.wikipedia.org/wiki/Dynamic_device_mapping) which allows pretty much instant switching.

#105I'd love to see something like this but the other way around - a native implementation of a Bluetooth mouse and keyboard in either Android, an iPhone or a RPi with a touchscreen. It would make life in a server rack so much easier if I didn't have to lug around a physical keyboard and mouse...
For Android there is an app that does this.

Re: Show HN: Bluetooth USB Peripheral Relay – Bridge Bluetooth Devices to USB
#106So it's basically what I would expect to get if I asked for a generic Bluetooth dongle.
Not quite, if your PC has a policy that disables Bluetooth, a BT dongle would not work either. That’s where this relay comes in—it bridges Bluetooth to USB, so you can still use your devices.
But that's exactly what I would want in the first place. Take my square and make it look like a circle (not a square with rounded corners).

Be careful with these though, a lot of USB switches (most readily available ones, even) aren't wired correctly and can result in current flowing from one computer to the other.

#108This is awesome! I have some serial devices (RS 232) that I've wished I could make wireless. Are there any similar projects to bluetooth serial comms?
You may find esp-link interesting: https://github.com/jeelabs/esp-link
I've built a WiFiRS232 bridge using the firmware, ESP8266 and a UARTRS232 converter module.
All hardware is very cheap.

I had a similar problem but dual booting windows/linux. Though I managed to share the link keys with some registry hacks in the end.

#110I have a USB switch, this will help me to use with my bluetooth devices.
Thank you!
