Remote debugging an NRF52 with GDBServer on a different machine from VSCode and Cortex Debug

remote-debugging.md

On the target machine: JLinkGDBServer -Port 5555 -device NRF52 -if SWD

In VSCode locally, add the following config block in launch.json:

        {
            "name": "Remote Debug",
            "cwd": "${workspaceRoot}",
            "executable": "build/src/myapp",
            "gdbTarget": "192.168.22.6:5555",
            "request": "launch",
            "type": "cortex-debug",
            "servertype": "external",
            "device": "nrf52",
            "interface": "swd",
            "armToolchainPath": "/usr/local/arm/bin"
        }

servertype "external", and gdbTarget are the keys to get it working
