I have two LH v1.0 mounted on my wall in front of my Viper simpit being used with my 8KX. It is probably a hardware related coincidence but I just updated to firmware xxx .255.295 and noticed one of them has a blinking red light. I have read that is most likely some type of hardware error. In Steam VR and Pitool is shows them both as registered (both blue in Pitool) and I can see them in the Steam VR room working and the tracking is still great. I see the 3 lines of red dots and I can feel the slight vibration of the LH if I touch it.
I do have a backup one in a drawer but is this a warning that it is ready to fail or has it already?
Did the lighthouse work fine before you update the firmware to 295?
If it did work flawlessly before the update, we suggest you try to downgrade the firmware and we will forward your issue to the tech team, so that they are aware of this matter and sort out the solution.
Yes it did work before - but the other one is working fine. I used one with my 5k plus for over a year then added the 2nd LH v1 a few months ago and then the 8KX in September. Only one of them is blinking red as the other one is doing just fine. is there some type of firmware for the LH that I would need to try ?
I will keep using the current firmware as I am still getting good tracking currently and will wait to hear what I should try with the LH that is blinking red.
Blinking red LED on the base is an indication of a hardware failure (of the base). Nothing to do with the Pimax firmware. It will blink exactly the same way with Index or Vive. The fact it happened just after a FW update of Pimax is a coincidence.
You could try to figure out what is wrong by checking lighthousedb.json file, but this will probably won’t help to fix it.
That’s the conclusion I came also, thank you for the link. I had another one in storage that I brought out and it booted right up. They will not last forever as they do have moving parts . . …
I will see If I can mess with the bad one and update the LH firmware on it for fun.
The reason why I am asking about what did you do exactly is that you might have actually flashed an old firmware to your base, which did not fix anything, but instead “unmade” the diagnostics, which had made the LED flash red in the first place. But you do not have to tell me .
I followed these exact instructions just like outlined in the link below. The files where on my system – if these are the old ones where are the newer ones?
You will need two files:
lighthouse_tx_htc_2_0-calibration-rescue-244.bin
lighthouse_tx_htc_2_0-244-2016-03-12.bin
The procedure is much like upgrading manually, but you do it twice, once with the fix-up firmware which will try to fix the base station, then once it has completed the fix, again with the current latest firmware.
With the base station unpowered, connect via a micro-B USB cable to your PC.
Hold the mode button down and plug in the power lead.
You can release the button once it enumerates as a USB mass storage device.
The drive will be called “CRP_DISABLED” and contain one file “firmware.bin”, delete that file.
Copy over onto the drive the “lighthouse_tx_htc_2_0-calibration-rescue-244.bin” file.
Once the copy is complete, pull out the power lead.
Wait a few seconds then plug in the power again. Be sure not to press the mode button while powering it up this time.
In a couple of seconds it should rapidly flash green or red. Green means it succeeded.
If it is flashing red that means it couldn’t automatically fix it and I’ll need to look at the unit to work out why.
Unplug the power again.
Repeat steps 1 thru 7 but using the “lighthouse_tx_htc_2_0-244-2016-03-12.bin” firmware file instead of the rescue one.
The base should now be working again, confirm by setting its mode to “A” and tracking with it alone (the other base turned off). Once it is confirmed working you can add back the other base.
If you wrote lighthouse_tx_htc_2_0-244-2016-03-12.bin to your base, you effectively “downgraded” the firmware to the version, which does not support the hardware diagnostics. The fact that your base now shows green light does not mean you fixed the problem. It just does not show it has a problem.
You should flash the latest firmware to the base (lighthouse_tx_htc_2_0-436-2016-09-20.bin), which does support the hardware diagnostics. Then run the base and if it blinks red again, and at least the IR LED array works, you should be able to find the reported error in lighthousedb.json (as explained in my linked post).
Yes - that is exactly what happened - red blinking now but I have all other lights. I have to try and work it with my Pimax not to update the json file to see the fault number. But, either way I’ll just by another if I need to. I will for fun, open this one up and see what I see. . . .
