UDP handshake listening error

[ArranWool]

I have a pico 4 with nightly ALXR from 2023.04.09 (alxr-client-pico-v4.apk). ALXR runs OK but only shows a blank screen with cubes representing the controllers (which are tracked).

ALVR 19.1.0 installed on windows 10. Setup wizard completes OK. SteamVR runs OK and shows the headset active (but NOT controllers). ALVR shows the IP address of the client that I manually configured (which I think means 'connected') as trusted. Both PC and headset are on the same subnet.

I get in ALVR very often the warning:

UDP handshake listening error: A message sent on a datagram socket was larger than the internal message buffer or some other network limit, or the buffer used to receive a datagram into was smaller than the datagram itself. (os error 10040)

Headset is pingable. Disabling firewall doesn't help.

In the ALVR connection tab, I tried changing connection to UDP and increasing buffer sizes but still blank screen in ALXR.

ALVR v19 and v20 are not compatible with ALXR. Install both v20 ALVR client and streamer instead.

Thanks for the quick feedback!

I want to use ALXR for the passthrough. So I guess I need ALVR v18.2.3 for that ?

Or does the ALVR client support passthrough now ? Sorry, bit confused about the two different clients.

Passthrough is planned but not yet implemented. In the meantime you should use ALXR + ALVR v18.

Works, many thanks.

Feature request: configuration of the passthrough color. In an absolute perfect world it would be pickable on the client from the image being show in the headset to avoid having to guess values :-)

Yeah the option will be available. maybe there will be also depth-based keying. For now ask any feature request in the ALXR repo.
