Headset disconnecting with BrainViz

[Watson Duncan]

I have been using the Insight with BrainViz and Bandicam to record long sessions, but I am finding that the headset disconnecting after typically 15 – 20 mins, and thus I’m missing valuable data.  This is especially troublesome when I am recording a long meditation session.  It appears that after a minute or so of little brain activity, the headset briefly disconnects.  If I am watching the screen I can reconnect immediately and sensor contact is at 100%.  There is no head movement at the time.  I have tested and confirmed similar behaviour wearing the headset at my desk with BrainViz running.  Why is the headset disconnecting?  Laptop with USB dongle is less than 1.5 m away, headset close to full charge, laptop doing nothing else other than BrainViz and Bandicam.  Sensor contact is 100% and I’ve check that are hydrated.  I would like to be able to run 1 to 2 hour sessions with dependable headset connectivity.

Hello Dubcan,

Thank you for your question. We are sorry to hear you are experiencing these inconveniences. This connection dropout problems sometimes happens if the receiver is located close to a WiFi, Bluetooth or other 2.4GHz transmitters – which is often the case in a PC where the antenna is located conveniently next to the USB ports (Mac also has frankly awful electrical isolation so the entire case probably oscillates at 2.4GHz). We always use and strongly recommend using a USB extension lead or powered hub just to get the receiver out of the noisy environment next to the PC. Place it in clear air away from radio sources and in clear line of sight to the headset and your wireless issues may disappear. Hope this helps. Let us know if you need anything else.

Thanks, that does look like it was the problem.  I’ve used a 1.5 metre USB extension lead and it hasn’t dropped out again yet.  It’s easier to use with an extension lead too as the laptop can be placed further away.  I don’t remember reading the recommendation if it was in the installation notes, but clearly operating the receiver dongle with a USB extension lead is a really good idea.  Thanks.
