I’ve never really understood the details of what makes bluetooth work or not work. References to the “stack” didn’t mean much to me. Only “stack” thing I can recall doing was with programming long ago where, if I recall correctly, you may store a value in a stack which would be pulled off for use later in the code. Don’t know if the BT stack is similar in concept.
Anyway, reading lots of comments from people who at least talk like they know more than me, I’ve decided there aren’t many people who really have a handle on this. And considering how many BT issues people have, that may include people making stuff that provides or uses it.
So, I thought I’d list some thing that I’ve never seen explained and see what answers I can get. This will have to do with BT interference.
Some key sources of interference:
Microwaves ovens, usb 3 including type A and type C connectors, cables connecting usb 3 devices. In the questions below, let’s assume none of these items are poor quality, but less than flawless.
Let’s just focus on keyboards for the moment, since this is a keyboard forum, and how interference becomes an issue.
First question: if there is a problem with interference, is it only affecting the computer the BT device is connected to or can if affect the keyboard itself?
IOW, would the keyboard be able to send everything properly regardless and it is interference with the computer which causes delays, disconnects, etc OR can the keyboard be affected so it doesn’t even send stuff on time or properly?
Second question: since usb 3 ports can cause interference, would a usb hub that is powered to an outlet, but not to a computer and no devices plugged into it still send out interference from its ports (like maybe if you have a hub used just to charge phone, tablet, watch)?
What if the hub is plugged into the computer but no other items connected to the hub - would the computer usb 3 port or the usb 3 ports on the hub or the cable connecting them still cause interference?
Third question: similar to above but suppose you have a hard drive connected (all with usb 3). Does interference potentially happen all the time, or only when data is transferred?
Fourth question: since cables can produce interference, which is better - to use short cables to connect an external drive to the computer (thus the drive’s ports are close to the computer OR use longer (2-3 feet?) to get the drives further away?
Fifth question: would there be any meaningful advantage to having the computer on top of a wood table and the drives beneath it (could be reversed with a mini) or does interference pass through such things too easily (or bounce around so much that it won’t matter?
