evirtual Posted March 12, 2018 Share Posted March 12, 2018 We are using a USB host board with a battery connected to USB of the vive tracker to send data and everything is ok. But, when connected to USB host, the vive tracker is charging and it is an issue as we have also a battery for the USB In guidelines documentation v1.5, p29, there is a variable called chargeEnabled in the setFeature data format. However, it seems not working as setting this flag to false, the vive tracker still charging. The documentation says that this variable is "RESERVED", what does it means?

HackPerception Posted March 12, 2018 Share Posted March 12, 2018 , I've pinged the tracker team who can comment on this. Link to comment Share on other sites More sharing options...
evirtual Posted March 13, 2018 Author Share Posted March 13, 2018 Ok, thanks This charging issue can be a strong limitation because instead having 10 hours for the board we have much more less Link to comment Share on other sites More sharing options...
HackPerception Posted March 15, 2018 Share Posted March 15, 2018 , Haven't heard back from the tracker team. Will push again. Alot of people are traveling for GDC so that may be the reason behind the delay - they're normally pretty quick. Link to comment Share on other sites More sharing options...
HackPerception Posted March 16, 2018 Share Posted March 16, 2018 , I have an update: This specific variable is not currently enabled - hence the "reserved" status in the documentation. We do not a timeline to enable it. Sorry that feature isn't currently supported! To any developers who may be reading this and require this feature - feel free to comment here so we can collect feedback to pass back to the tracker team.

evirtual Posted March 17, 2018 Author Share Posted March 17, 2018 Thanks for this quick feedback. Indeed, we are a company and we are developping professional training solution supported by VR simulation For some application, we are using some dedicated accesories to improve interactivity and realism of the simulation and thus obtain better training performance. So, if we need to have a cable to supply power to the accesory because we cannot disable charging of the vive tracker, we will have to think about another technology. It is quite strange that USB communication capabilities have been implemented on the Vive tracker, meaning that we can develop specfic acccesory for a better VR exprience, but due to this charging issue the VR experience will be much less immersive due to this cable. Is it possible exchange in MP to identify who we can contact to discuss about that and other items, like an access to a vive pro dev kit...
