I tried disconnecting my Bluetooth speaker, then everything works fine but whenever the Bluetooth speaker is connected the WiFi becomes so slow that I barely can use the internet.
Disconnecting the Bluetooth speaker fixes it but I need to connect my Bluetooth speaker as well.

i have some questions for ble conneciton between smartphone with bluetooth earphone.
after pairing/bonding the bluetooth earphone, when i turn on bluetooth earphone, my smartphone automatically connect to the bluetooth earphone.
how it can be? the smartphone periodically try to connect (send connect request packet) to paired devices?
i don't think that job includes advertising/scan because the connection has completed so quickly right after bluetooth earphone turn on.
maybe.. i think the smartphone periodically try to connect to paired devices..
is it right?
I'm trying to make an Android application for Android Things running on raspberry pi that takes USB joystick inputs (including DJI Mavic controller) and passes it over BLE HID as a gamepad.
Windows, Oculus Quest and Mac all recognize it as a gamepad, but when I try to connect to it, they connect and disconnect right away. I'm not sure why
Is there any tool on any OS that logs the BLE HID pairing process to find out what went wrong?

i'm using Bleno (https://github.com/sandeepmistry/bleno) for a small BLE project.
I've started with no problems on Raspberry Pi2 but switching on Pi3 i found that:
If i connect to my "BLE Pi3" i can interact with the device only for 2-3 seconds, then i get disconnected (working on Pi2)
If i try to read/write characteristics i receive a permissions error and i can't do anything (working
I am currently working on a project that requires communication between an android phone(galaxy s4) and an Atmega8 microprocessor. To connect these devices wirelessly I'm using an HC05 bluetooth module and to understand the connection I'm using pre-built arduino codes(turn LEDs on and off) and an android app called blueterm. This connection is established and able to transmit data when connected to the Arduino uno, but as soon as this chip is removed and connected to a standalone breadboard the connection fails. The standalone breadboard works fine and has been tested with many other projects and I have attached the breadboard connection below. The HC05 when connected to the breadboard changes the blinking pattern to notify the user it is connected but the serial connection is never made. Any help would be greatly appreciated, if any other information is needed feel free to ask.

I bought one of those tiny bluetooth USB dongles that you can plug on a PC and make bluetooth communications. I am wondering if I just plug this dongle to a USB power source, like the USB charger that comes with iPad, can the bluetooth dongle power up, and be discovered as a bluetooth device? This sounds reasonable, since the bluetooth dongle should be able to broadcast itself, at least using some low-level protocol, i.e. showing its Mac address.
However, I tried to do the following:
1.Plug the bluetooth dongle on my iPad's usb charger
2.Search bluetooth devices on my laptop
and I could not find it. Is it because the bluetooth dongle needs the PC to initialize it, so that it can be discovered? Or I am not doing it right?
Thanks
It depend on the dongle
Typical PC dongles depends on the host (pc) to initialize and start any bluetooth activity - including scanning etc
It is practically possible to make dongles that can start becoming discoverable without waiting for host initialization. This has to be a custom build
