3 years ago Oh, it looks like it's failing to establish a websockets connection. Keystrokes and mouse events go over the websockets channel, so that's why they're failing.
Can you share the logs by running /opt/tinypilot/dev-scripts/dump-logs?

3 years ago Here you go http://sprunge.us/Z8NPw9 Please note that I have changed my client from a routed network to the same broadcast domain as the raspberrypi, first the client appeared as the NAT GW (172.29.1.108) later it appears directly (172.29.1.160).
I also run tcpdump on my client to see if there are connection attempts from pikvm, but there are none.
Could this may be related to this error message (from the tinypilot journal)?

3 years ago My browser gets this as well as a response by nginx to all the /socket.io/ requests (which return a 400):
"The client is using an unsupported version of the Socket.IO or Engine.IO protocols"Looks like the socket.io/engine.io version in nginx is too old. After downgrading the pip packages it somehow seems to work:
$ sudo -u tinypilot /opt/tinypilot/venv/bin/pip install 'python-socketio==4.*'

3 years ago That's strange. When I connect the raspberrypi to ethernet instead of wifi the error messages disappeared and the latency improved tremendously. The client is still on wifi and normally I don't have issues with the wireless connections (using Unifi equipment).
Is it possible that the wifi chip in Raspi 4 is just crap? Any suggestions how to operate the tinypilot over wireless networks?

3 years ago Thanks for the heads up! This turned out to be a bug in Flask-SocketIO. I fixed it in #370
You should be seeing performance a little bit slower over WiFi but not 10-50x slower.
Are you still seeing those errors in the logs?

3 years ago Thanks Michael!
The fix works well. Over LAN I don't see those error messages. Wifi is still slow like hell it it seems to delay is stacking up. I'm going to get a USB wifi device and see if that has better performance.
I have installed tinypilot as described on top of raspios (2020-12-02). See log below. The HDMI part works fine, but keyboard does not. I have tested several USB-C to USB-A cables to no avail.
What also looks strange is the "red" button indicating "Could not connect to TinyPilot:" There are also errors in the developer tools see screenshot below. I'm using Chrome.
