Wireless Display Adapter v2 and Bluetooth problem

Question

Hi Community!

I turn to the community in hope to get attention of Microsoft to fix their product's issue. I have a Surface Pro 4 (Core m3 version) and a Wireless Display Adapter v2.

First my Surface succeed to connect to the adapter always the second time. My friend has a Lenovo y580 (4 year old laptop) and it works great with the adapter, and it also can connect for the the first try.

Secondly, the connection with the WDA v2 lost every time I connect or reconnect a Bluetooth device. It is really big problem that I can not use my Surface Pen 4 side by side while it is connected to WDA. Because connecting or disconnecting a bluetooth device while the connection is active with the WDA makes the connection lost, and the Surface Pen 4 disconnects from the Surface after a period of inactive time, and if I move the pen again, it connects to the Surface and the connection is lost with the WDA v2.

Is Microsoft developing new update for the Surface Pro 4 Wireless adapter, including WI-FI and Bluetooth adapter? Do any of you experienced this problem?

Answer 1

Basically, Miracast establishes a connection using 2.4GHz wireless, and can

conflict with Bluetooth which also uses 2.4 GHz wireless. Miracast can use 5GHz

wifi, but needs to establish the connection first using 2.4 and then switches.

The spec for Miracast would need to be changed for all communication, including

negotiation to occur over 5GHz

For best results:

1. connect your Surface to wifi using 5GHz wifi
2. don't use any bluetooth peripherals until the connection is established via

Miracast with the remote display and the session is started

3. after the session is started, you SHOULD be able to use bluetooth devices.

I've sent this in to a contact at Microsoft. They've been very slow at

responding to Miracast issues.

I had your problem too. After I update my system to Win10 anniversary upgrade (14393), this problem disappear.

If you haven't upgrade to Win10 AU, I would suggest you to be cautious. For me, at this time, this upgrade has caused more problem than it solved. The problem of twice connection to WDA v2 has been solved, but there are lots of other issues. MS just release an update to fix CPU power setting. (Can you believe it? I have waited one moth for this. In August, my Surface Pro 4 had very POOR battery life. ) And that is not the end of AU's problems.

Anyway, this problem of WDA has been solved. All you need is to wait another month till they fix most issues of Win10 Anniversary Upgrade. Then you are good to go.
