How to run it?

[xaionaro]

I made

yarn install
yarn build

And after that:

nodejs ./examples/scan-for-devices.js

However I got:

xaionaro@void:~/src/node-osmo$ nodejs ./examples/scan-for-devices.js
Starting DJI device scanner...
/home/xaionaro/src/node-osmo/node_modules/@stoprocent/noble/lib/hci-socket/hci.js:503
  this._socket.write(cmd);
               ^

What is the way to run the tool? :)

When I try to run the other script, it just hangs:

xaionaro@void:~/src/node-osmo$ nodejs ./examples/connect-to-device.js 0 osmoPocket3 OsmoPocket3-XXXX XXXXXXXXXXXX rtmp://192.168.0.131/asdf/asdf

(I also tried to modify: it had osmoAction4 hardcoded and it ignored my arguments)

Also how to find out the deviceId?

[datagutt]

Seems like the last commit broke something. I was trying to fix cross-platform compatibility.
Even reverting that, I suspect you might get some error when trying to parse the messages from the dji.
I cant for the life of me figure out the exact platform, dependencies and commit where I got everything working.
I know i had it working on my Action 4 at one point

As far the hard-coded osmoaction4, i had some dumb issues and ended up hardcoding it.
The device id should be returned from the list-all-devices

[xaionaro]

I tried to revert one by one last few commits: neither of them work.

The same error:

xaionaro@void:~/src/node-osmo$ nodejs ./examples/scan-for-devices.js

Look at the instructions about running noble on: https://www.npmjs.com/package/noble
It needs to run as root and requires nodejs to have some additional permissions.
I did:

sudo setcap cap_net_raw+eip $(eval readlink -f `which node`)
sudo setcap cap_net_raw+eip $(eval readlink -f `which nodejs`)
sudo NOBLE_HCI_DEVICE_ID=0 nodejs examples/scan-for-devices.js

Starting DJI device scanner...
Powered on

    and model Osmo Action 4

  rtmpUrl: undefined,

...

I updated noble with pnpm install noble too.
