What kind of device are you trying to connect to?

ttyAMA0 is the Raspberry Pi's built-in UART - it'll be sending characters to a pin on the Pi's pin header.

It's a good sign that is working - if you plugged in a USB device it should appear as /dev/ttyACM0 and assuming the baud rate is correct it'd work fine

Hello Gordon!

I am connecting to the Puck.js via Bluetooth LE.

I can not upload code and not type in the left lane.
:-(

My suspicions are falling on the page ... See!

1. The page makes several calls to / serial / ports, but after connecting the last call stays open until timeout.

2. When disconected the server docker crashes with error.

What do you think?

I think that's fine.

As I said above - ttyAMA0 is the wrong port - it's not surprising nothing happens.

And you're trying to connect to Puck.js? When you first start the IDE server, does it say anything?

Most likely you just hadn't entered the command:

sudo setcap cap_net_raw+eip $(eval readlink -f `which node`)

before running node.js, so it doesn't have access to the BLE device

When I start the IDE serve say only "listening port xxxx"...

I was run setcap, but nothing! Problem continue!

Have you connected a Web Browser to localhost:8080?
