Controllers and Lighthouse not working with Pitool and 8KX

Pimax Hardware P2: 8kX
1

Hi Everyone,

I haven’t received the deluxe package for my Pimax 8KX so i bought the vive controlers and 2 2.0 lighthouses.

In the Pitool only 1 light house is showing active. I’ve plugged it in and unplugged it about 5 times, controllers pair but can’t see hands in Steam Home and can click to see move spots but have no teleport options to move. Controllers aren’t working.

This reminds me of the nightmare i had with the Oculus Rift initial set up and times when it screwed up.

What am i doing wrong? Do i have the wrong controllers. I still haven’t gotten the ones with the deluxe package so i got these from Amazon from HTC.

Are they V2 vive controllers?

Only vive pro (blue) ones will work with V2 lighthouses, I think.

I think You need to keep the channels below or at 6?

There’s a little button You can push to change channels on the back I believe (use a pencil or similar).

Where do you find channels? my Pitool doesn’t have options for channels.

You use a little pin/ballpoint pen to press the button in the little hole on the back of the basestations to change channels as far as I understand (I don’t have v2 lighthouses).

EDIT: Here’s a random pic of it (someone using a piece of thin electrical wire to push it):

I have to unplug my Pimax for a few seconds then plug back into the USB ports on my pc for it to find the base stations.

Thank you. I didn’t know there was a little pin hole on them. I’ll have to look at that when off work today

Next to were you put in the power in the lighthouse it is a button you can push, if you have steam vr running you can hower over the lighthouse to see what channel it is at.

Hi all,

just to be complete: yes, you can (and should) change the channel number on a second, third, … lighthouse V2. Operating 2 on the same channel does not work - only one will be detected.

  • I’ve tested to set mine to channel 0x01 and 0x02, respectively.
  • You’ll need Renesas GATTBrowser App (or any other means to connect to BLE devices and modify settings).

A) To read a lighthouses channel number via BLE advertisements:

  • Open RENESAS GATTBrowser
  • Tap on LHB-12345678 (not the blue play arrow, just anywhere else in the line)
  • The Raw-Data section flips open
  • Under “Manufacturer Specific Data”, find a string beginning with “055D: 00 02 ?? ...”
  • The third number is you channel number, it is advertised frequently, also in stand-by state

B) To read/change the channel number via BLE characteristic:

  • Press the blue play button of the lighthouse you want to change the channel for
  • GATTBrowser now connects to the lighthouse
  • Find the line that starts with “00001524-1212-...” and tap on it
  • Make sure to press the “Read” button.
  • Below there should appear the exact same value as from section A) above, e.g. 01 for first channel
  • Under the Write button, there is a line for text input; type a new channel number, e.g. “02”, there
  • Make sure that next to the Write button, “Hex” is selected from the dropdown component
  • Press “Write”

In case the Lighthouse was spun up and you have very good ears, you will notice a faintly changed sound pattern.

Hope this helps. Cheers.

If you see the lighthouses in SteamVR, you can use hmdq (https://github.com/risa2000/hmdq) to see which channels are they running on. It spits them as ModelLabel property in the list of properties of TrackingReference (which is SteamVR nick for the lighthouse). It will also show you the corresponding serial number, so you can relate the two.
