I have a windows 10 laptop + 3 monitors, and whenever the dislay is turned off (power options, or restart) the display settings have to be reset to configure the monitors in the desired positions. The monitors are connected via:
1x - USB-C dongle/adapter --> HDMI port
2x - USB-C dongle/adapter --> 2x USB adapters ports
Is there some way to automate this configuration so that I can schedule it as a task?

Can anyone tell me what is wrong with my tool bar for wifi/battery/sound?
Battery shows X mark
No Audio output on laptop speaker
Cannot control brighness
connected to wifi and bluetooth device but its greyed out
the battery % sign is only shown not the actual battery remaining number
When I open bluetooth settings, the windows auto closed in 1 second.
I have latest windows update installed.
I am required to implement functionality for switching Wi-Fi access points based on priority i.e. if Linux device is connected to Wi-Fi "A" and another Wi-Fi access point "B" with higher priority appears the device should automatically switch to wi-fi "B". Can anyone help me out?
I have set different Wi-Fi access points priority using wpa_cli and if I restart my Linux device it switches network according to set priority but if the device is already connected to some network it won't switch.
I've enabled Hyper-V on my windows 10 PC and created External Connection via the Virtual Switch Manager and was bridged with my Wifi USB Adapter.
After this my download decreased from 100 Mbps to 2 Mbps. Upload is fine.
I've tried to change Microsoft Network Adapter Multiplexor Driver -> Large Send Offload Version 2 -> Disabled (both IPv4 and IPv6) but no luck.
Any ideas that I can try to restore my internet speed?
My PC is using usb wifi adapter to connect to my router as I don't have physical lan cable.
I have this doubt. For example, I have a Smart Wrist Band (measures pulse, body temp), a Smart Gear/Watch (to display text alerts, control calls) and a Bluetooth headset. I need all the three to communicate with my mobile phone at the same given instant.
Is it possible to achieve the same ?
What are the challenges involved if I need to develop an application on my own if I had to achieve the above possibilities ?
Your help is highly appreciated.
Note:
- BLE has star-based network topology and maximum devices per Piconet is 8 including the Master
- Please help me in understanding/visualizing the above theory that I learnt.
Thanks.
The Bluetooth Classic has a limitation of 7 slave devices in a piconet and they are time and hop synchronized to the master ( ie master and slaves share a common physical channel and it is not possible to address more than seven slaves for a master when in Active mode).
In BLE each connection from a master to a slave operates in an independent physical channel( ie LE slaves does not share a common physical channel with the master), hence there is no limitation imposed by the Specification except as specified by the Connection interval and slave latency rules ( Note that individual bluetooth controller manufacturers may decide to limit the number of connections depending on the practical bandwidth limitation).
please see the Bluetooth Classic vs Bluetooth Low energy Topology below.
Is it possible to achieve the multiple sensors ( BLE) and Headset (BT classic) connected to mobile?
Yes it is very much possible, except that there are some BT4.0 controllers which doesn't allow LE advertisement while connected to another BLE device. please check the known limitations in a particular bluetooth controller.
It's the Bluetooth controller that has the limitation. Different Bluetooth controllers have different maximum number of concurrent connections. It's usually between 5 and 14. However Android has an additional hardcoded limit of 10 for some strange reason.
Other than this, there shouldn't be any particular challenges.
my .net app on the computer needs to make the computer discoverable, start a service and then wait to accept incoming connections. my app/computer is the slave and connecting device is the master. So I change my local radio mode to discoverable programmatically,start my service and wait... But when the device is supposed to connect to my app/computer, nothing happens.
Windows help and support has this :
Control Panel ->search for bluetooth -> click on change bluetooth settings ->
To make your computer discoverable to Bluetooth enabled devices,
select the check box for Allow Bluetooth devices to find this computer.
When a Bluetooth enabled computer is in discovery mode, it broadcasts a
wireless signal that allows it to be detected by other computers or devices.
This is sometimes called pairing mode. If you check this box, your computer
will still be able to detect Bluetooth enabled devices that are in discovery mode,
but they will not be able to detect your computer.
I am not quite sure what's the context. If I leave that box checked, then other devices will be able to detect me (because I am set to discoverable), but won't be able to connect????? So my service just keeps listening, won't be able to detect any incoming requests? Am I right?
