Connectivity issue?

No worries you can also find Bluetooth when you search in your control center - it should be under "Hardware" category (If you made full install and not just minimal it should be installed by default but also your system does need to support Bluetooth connecting)

It is hard to write technical material. I was a technical writer for 2 companies and it was hard.

Please see my earlier reply.

I modified the commands to show the explicit form to use, if your computer is reporting any devices which could be identifiable as Bluetooth and available for connection.

29

If the echo is not visible as an "IP" device, then the only other option is to attempt to connect as a Bluetooth device,

  • IF     the echo is Bluetooth capable,     and
  • IF     your computer is Bluetooth capable.

for existence of a Bluetooth interface, you would need to use the command, and see the report, as shown in this example (from here):

inxi -Eaz
Bluetooth:
  Device-1: Broadcom BCM2045B (BDC-2.1) type: USB driver: btusb v: 0.8 
  bus ID: 1-1.4:3 chip ID: 0a5c:217f class ID: fe01 serial: <filter>
  Report: hci0 state: up running bt-v: 2.0 lmp-v: 3.0 sub-v: 2ec 
  address: <filter>
  Info: acl-mtu: 1021:8 sco-mtu: 64:1 link-policy: rswitch hold sniff park 
  link-mode: slave accept

( Also some useful links in the second reply on that URL. )



To identify any Wifi internet hardware, use the command

inxi -i

and you should see something making reference to "Wireless Adapter", such as in this (from here):

Network:   Card-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller driver: r8169 
           IF: eth1 state: down mac: 60:a4:4c:3f:b8:82
           Card-2: Ralink RT3072 Wireless Adapter driver: rt2800usb 
           IF: wlan1 state: up mac: e8:4e:06:08:b1:cd
           WAN IP: 201.141.199.56 IF: eth1 ip: N/A IF: wlan1 ip: 192.168.0.11

In your earlier image of the internet connections, is the visible reference to "hugh733536"

  • a known unrelated WiFi for other uses,       or

  • the name assigned to your Echo gen3 by another buyer who returned it to the store ?

So ... "inxi -i" is telling you that you have no Wi-Fi interface.

What about the response from this command, which would tell you if you have a bluetooth interface ?

Well ... that sums it up!

Your computer does not have the hardware for either of WiFi or Bluetooth. :frowning:

To "plug in" your Echo, you will need to either

  • (if you have a spare slot on the motherboard) purchase an interface card for the interface type you prefer (WiFi or Bluetooth), or

  • (if you have a spare USB port) purchase a USB transmitter/receiver for one of those two (search for "Wifi USB adapter" or "Bluetooth USB adapter".

I just confirmed the specs for the Echo gen 3. It supports both Bluetooth and Wifi. :slight_smile:

If you buy a Bluetooth USB dongle make sure it says it supports Linux. Many manufacturers do not

If you do decide to buy Wi-Fi USB adapter or Bluetooth dongle these links could be proven useful since they provide information about which product is Linux compatible:

And in this reddit topic there are some interesting relatively recent reviews of some of those Bluetooth dongles and what are best suited for Linux:https://www.reddit.com/r/linuxhardware/comments/t7hzdb/which_usb_bluetooth_dongle_would_you_recommend_me/

Thanks guys. I have a dongle already there. I think it was for my wireless mouse that I once had. I want to know if I can unplug it and use that slot.

Is this the right one?

I have the ASUS BT-400 (you can find it on Amazon), Linux works.

I briefly looked at the link you posted, it might be only win10/11.

I looked at the reviews and when you Ctrl+f "Linux" keyword two people said it seems to be Linux compatible in spite the fact it doesn't state at the product info segment so my guess is it might work

From the link you've provided this seems to be the best answer: "Product says windows compatible only but works as good on Linux. Plug it in & it’s ready to connect immediately on both OS. Locates & connects devices quickly.
Linux users this is the adapter you’re looking for!

Regarding the review that when plugged into usb 3 slot creates issues. That’s true as usb 3 ports use range of frequencies that conflicts with the specific frequency BT devices all use."

If your dongle came with your old mouse, then it is specifically tuned ONLY for that mouse. It will not work for any other device. :frowning:

So, yes, that can be unplugged and trashed.
