3800 Remote control

So how exactly does my 3800R remote control communicate with the Roku stick.  Is it via bluetooth or somehow via the wi-fi network controller.   I ask because I'm having some problems turning the TV on and off using the remote and I don't know how the remote is communicating.  I can't find this answer anywhere clearly.

Re: 3800 Remote control

I think the TV control is actually via IR if you are using the On/Off button. The actual communication to the Roku itself is Wi-Fi Direct. There's a direct connection between the Remote and the Roku, doesn't connect to your Wi-Fi Router at all.

As trekkeriii said, the remote communicates Stick commands via WiFi Direct, and TV commands via IR.

Since WiFi Direct (or any RF) isn't line of sight in your viewing area, you don't have to point the remote at the Roku for it to work. However, since the TV controls are IR, you do need clear line of sight. Many TVs have the IR sensor on the lower edge of the TV, meaning it's easy for stuff to block the light.

Try it. Put your hand over the end of your remote and point it away from the TV. Press the HOME button. It works. Press UP and DOWN arrows. They work. But press the volume control. They don't. Now, remove your and and point it at the TV, ensuring the remote has an unobstructed line of sight, even if that means raising the remote to eye level. The volume works.

I suspect the problem is the line of sight is blocked when you're experiencing those issues.

Re: 3800 Remote control

OK. I now understand the the TV on/off and volume control are via IR.   What I don't understand is what "WI-FI Direct" is.   How does that work?  One response is that it is a direct connection between the remote and the ROKU stick.  Is that correct?   Isn't this just an RF connection?  I don't understand the use of the term WI-FI direct.

Look into this new thing called Google. It's great. You'll love it! I can't wait for it to catch on. https://www.google.com/search?q=wifi+direct
