bluetooth USB adapter for Inspiron 1545 running Ubuntu 14.04?
I'd like to use a cheap, wireless bluetooth speaker close to where I use
my laptop and I would appreciate recommendations for a cheap USB bluetooth adapter that would work. I'm in the US. The only somewhat useful data I've come across so far was he https://wiki.ubuntu.com/HardwareSupp...othUsbAdapters however only one actual adapter is listed for Ubuntu 14.04 and it runs like $50 US, way more than I care to spend! Other adapters there work fine for earlier versions, but that doesn't mean they'll work with 14.04. Unfortunately, although some 1545's came with already built in bluetooth cards, mine wasn't one so no go there. Thanks in advance. |

One thing you have to remember about hardware manufacturers, is they're inherently dishonest. http://www.speedlink.com/?p=2&cat=28...47434efedcbbd3 If "Cambridge Silicon Radio Ltd" is not mentioned but "Realtek RTL8723" ... That means the adapter does not have a constant composition with time, and all the adapters are considered "interchangeable". This is important, if you have the idea that somehow BlueZ only works with a CSR radio. When Startech makes product, they always mention the chip number used on their website, so at least you have a chance of getting a "certain chip" when you buy. ******* Why not grab the GBU521W6 for $11 and if it doesn't work, throw it away ? That one is at my computer store right now, so a ten minute drive I could have one. No need to pay shipping. I could drive my bicycle to save gas. Etc. Of more concern is range. I bought a pair of throwaway BT plugs, and they worked together at maybe six feet or so. I set up a piconet and managed to squeeze through a few packets in a network test. They've sat in my hunk room ever since... for some reason. My interest in Bluetooth has declined significantly for some reason. Note that active USB3 cabling emits at 2.4GHz, and can interfere with other radio devices. While Bluetooth has frequency hopping (to prevent interference in a single bin from knocking out communications), the USB3 noise is spread broadly from 0 to 5GHz. A 5GHz Wifi is not affected by USB3. But 2.4GHz Wifi or 2.4GHz Bluetooth, could be. If a device operates in only USB2 mode (plug USB2 peripheral into USB3 port), then there should not be any important RF from that. USB2 spectrum, if it exists, doesn't interfere with computer activities. I would only consider tech like this if. 1) I want to run a Bluetooth headset while sitting in front of my laptop. 2) I don't care if it stops working if I leave the room to get a snack, leaving the laptop on my table. There are three classes of BT in terms of range. But if you check the reviews on the "long range" flavor adapters on the Newegg.com comment section, you'll find the comments a bit discouraging. Nothing that uses RF, comes with a guarantee. In fact, if you dropped down to your local landfill site, there's probably a small mountain of Bluetooth nano adapters there :-) While you're on the Newegg.com site, also check the reviewer comments for "thermal issues". Some adapters (for whatever reason), run extremely hot, when they really should not do that. When you first get the adapter, use the "fingers" test to make sure you have not received such a unit. Mine didn't get hot, but then, mine also didn't perform worth a darn (range, unusable). Have fun (and consider the experiment a throw-away...). My experiment had the *expected* outcome. I was prepared to be shocked, if it worked well. Paul |

I was prepared to be shocked, if it worked well. Paul Thanks. The only issue for me is that the closest computer store is 35 mi away, so a special trip unless I had to buy rare groceries which I do from time to time. I think I'm just going to forego on the bluetooth idea. The problem is really my Inspiron 1545. It has an audio issue I've never been able to solve. The audio will come out of the speakers just fine after boot up, but if I move the laptop in a certain way or bump it slightly, audio cuts out. If I then reboot, it's back. Sometimes, I'll move the laptop to the other table to go get something to drink and I'll hear the characteristic "pop" I'll sometimes hear and I know that I'll have to reboot to get audio back. When this happens, no audio on speakers or headphones. A week ago, I picked up a cheap USB dongle with audio out and mic in. This works fine even when the audio from the laptop speakers goes out, but I don't like the adapter sticking out of the USB as far as it does, plus the headphones cord. I've considered opening up the laptop, but it looks like quite a lot needs done just to reach the speakers and without the battery in place, I wouldn't be able to test anyhow. |
