@dlech Hi David, I have the same bluetooth connection issue in Mac OS. Does the ev3-browser extensions of the VSCode support for bluetooth connection. Because when I try to connect my ev3dev brick via bluetooth in VSCode, it will always throw out the handshake timeout error: "Failed to connect to ev3: Timed out while waiting for handshake." But the connection works fine via usb cable. Would you mind to share some info for this? thanks a lot

@dlech Hi David, having the same issue with windows 10. Pairing works fine but the EV3 does not appear on the device list. Tried to connect it also by its IP address but VS Code shows the "Failed to connect to ev3: Timed out while waiting for handshake" error. Thanks man

Same here. Windows 10, Paired without any issue. but the device is not listing when I try to do ">ev3dev:Connect to a device" in Command Pallet. Any updates on this issue?

macOS and Windows 10 are not the same as the original issue (Windows 7), so please open a new issue with the exact steps to reproduce the problem and we will see if we can figure it out. Windows 10 and macOS are both working for me, so I need to know all of the details to see what is different.

FYI, I had the same problem on my Mac, but after I restarting Visual Code, I was able to connect to ev3dev from the extension/device list.

Because when I try to connect my ev3dev brick via bluetooth in VSCode, it will always throw out the handshake timeout error: "Failed to connect to ev3: Timed out while waiting for handshake." But the connection works fine via usb cable.

In v1.1.0, the timeout is increased from 20 to 30 seconds. It is also now configurable via a setting if that is not long enough.

Hi, I was having the same issue. Pairing worked but the device would not show up in VSCode. It showed up in VSCode after I went to Wireless and Networks > All Network Connections > {PC-Name} > Connect on the brick.

I am able to pair from Mac (Ventura) to ev3dev, and ev3dev shows that it's connected to my mac.

But still VSCode EV3DEV DEVICE BROWSER shows it can't connect.

Oh wait ... I tried to reconnect (for like the 20th time today) and mysteriously it found a newly labelled ev3dev and it works!

Oh I wish I could tell you why it works now and didn't before. Bluetooth is a mess

solved: it was because I also had the USB connected. That always works.
