Not able to connect devices with external USB dongle

[eagleye2]

Hi!
I want to use an external Bluetooth USB, so with a usb cable extension I'd have a better reach to my Bluetooth devices. The adapter is green and hciconfig shows the following:
`sudo hciconfig -a; dmesg | egrep -i 'blue|firm'

I'm using "1" in the adapter since the usb is hci1.

Everything should work, but I'm not able to receive data to the USB dongle. if if switch back to "0" (hci0, internal BT), then data is receiving as always.

Where is the problem?

Thank you for your help.

To be honest I don't know. You could try asking in the iobroker forums, maybe someone there knows more about the hardware side of this.

Hey there,
im also try to setup this Adapter with a USB Dongle because im running everthing as Virtual Container / Virtual Maschines .. frist i get a "TP-Link U500 Nano USB Bluetooth 5.0" installed all the Linux stuff etc .. the Adapter wars Green and also in Linux everything looks fine but i cant find any devices.

i run every test and troubleshooting methode that i wars able find but noway. I cant find Decives via Scan (Linux Console / Iobroker Adapter) and i cant also not found the Machine with my Phone.

Now I have bought a "TP-Link UB400 Nano USB Bluetooth 4.0" and i can find the Devices via "bluetoothctl" (Linux Console) (my Phone) and also the Adapter found one the Devices but only with a MAC. The Adapter will not find my Phone but i think the Adapter is not made for what I had in mind (presence check with my phone via Bluetooth).

So i think you have the same Problem like me, your dongle doesn't work with Linux.

I hope it helps...

Greetings Milcho :)

Hi

Some additional information from me: My experience with TP-Link UB500 Adapter under Linux is also sobering. You can get it to work but it does not support Bluetooth Low Energy (BLE)! TP-Link explicitly say that they only support Windows!
