    Default Need Help 2 Bluetooth devices on samsung galaxy s4

    Today I purchased a bluetooth mouse and a bluetooth keyboard to use on my new galaxy s4. When I connected both, I can move the mouse and use the keyboard but the keys get "stuck" and will keep sending the same letter. The mouse will intermittenly stick and not update its location for a bit and then snap way out.

    If I recall correctly it says that that the keyboard keeps reconnecting.

    If I turn off one or the other device, neither the mouse or keyboard has any issues. Is this normal? Is there something I can do to fix this?

    The keyboard is a Logitech Tablet Keyboard, I can't find any other way to describe it. Here is a link to it.

    Amazon.com: Logitech Tablet Keyboard (Keyboard-and-Stand Combo) for iPad, iPad 2, iPad (3rd/4th generation), and iPad mini (920-003241): Computers & Accessories

    The mouse is an HP Bluetooth Mouse X4000b.

    Sorry, no idea how to fix.

    But I have to ask...why in the world would you (or anyone for that matter) want or need a wireless mouse and keyboard for a smartphone that's mere inches wide/long??

    I enjoy trying out various things. I also wanted to see if I could work an entire day from my phone. I was able to do that using various apps and ssh tools, and mirroring my phone onto a bigger screen. It was an enjoyable experience and I would probably do it again. It was slightly rough around the edges due to the mouse/keyboard collision issue.

    I also wanted to try out remote desktop and play "relaxed" games from my desktop on my phone. Keep in mind, not games that are twitch based or anything competitive, due to added latency. I was able to use a couple apps and play some turn based games while relaxing, away from my desktop.

    I want to push this device in different ways to enjoy as many facets of it! It's a great device.

    Hi, so after doing some research, it seems that Bluetooth is currently really buggy on 4.2.x and up. I used to be able to connect my PS3 controller to my android device over bluetooth, but when i upgraded to 4.2.2. i couldnt connect anymore. It seems the only solution is to downgrade to anything lower than 4.2.x (such as 4.1.x). Don't know how long Google is going to take to release an update for this bug but i wouldnt hold my breadth.

    Anyone have a solution?

    I have my BT earphones and BT keyboard connected all day everyday with no issues. So yes, connecting to multiple devices IS supported.

    You can pair with as many devices as you want.
    However simultaneous connection to more than one device is NOT allowed.

    Bluetooth has never allowed this, it's a limitation of the hardware.
    Currently it's point-to-point which means that it only allows one data stream.

    For it to communicate to multiple devices simultaneously it would need to be multi-point
    Only wireless headsets have multi-point technology right now.

    In the future this will probably change as tablets are evolving to replace laptops.

    My advice would be to use a keyboard dock with the wireless mouse. That way the keyboard is directly connected and won't interfere with mouse.

    well, I have been able to use the Torque Pro app with the bluetooth OBD2 adapter and my jawbone headset at the same time

    so i guess you can use 2 bluetooth devices at the same time on the s4
