Regarding the base stations I heard horror stories that some base stations come not preconfigured from Valve & while it’s easy to update firmware to those who have a steam vr headset like vive or index, it’s not possible with pimax though, so one buddy had to find somebody with vive/index HMD & use it’s wireless to flash FW to base stations through steam vr UI then it started working.
