Trying out using the extended Inquiry data search instead of the real simple one.  This allows us to hopefully get the name of the device as part of this, which now allows the PS4 to know it is a PS4 on the Pair type constructor.

Still WIP to understand XBox one...

Support to pair PS3 if it knows the BTADDR and user presses select and PS button and plugged in USB.

Remembers remote name, and tries to get it when PAIR version of code is running.  (Currently fails).

Does some mapping of PS3 Bluetooth data to match USB HID data.

Warning: as part of debuggigng why joystickType value was changing, I changed the class to make it a function you call instead of just a member variable.  Should mark it inline...  I think I caught all of the places in example code that was accessing it.  If we find we want ability for user probram to update it, should add another member to explicityly set it.

I have some PS3 support working... Hope I did not break PS4.... ;)

Also This assumes that you did a bind of the dongle to PS3 external, no support yet, I did this on RPI3...

Rumble needs work!

Hopefully did not break other things...

Find that the PS4 requires you to ask to connect versus some/most other devices will do the request...

Also found issue without printing, where adding a delay(1) in a couple of places appears to help when Serial1 printing is not on

Was issues not detecting that ISR bind was asked for, also not special casing when we are doing a bind to know which message to send next....

There are some of the BT dongles that have a device type of 0xff instead of the correct one, so added table of VID:PID to check against, currently only one in list.  If it is this pair the Bluetooth system will claim it.

PS4 starting to work, Still some rumble issues.

Also some WIP parts for caching remote name

Some of these changes also came from @mjs513

Still working on PS4

Again still WIP - but now have the Bluetooth object talking through a keyboard object...

With this update, I can now talk to the keyboard without having to repair each time.

Still WIP

Code is still WIP, needs lots of reorg and fix up and lots more to figure out.

But started working toward the Bluetooth HID devices and have the messages going back and forth from my BT dongle to a small BT keyboard.
It is finally showing keys being pressed and the like.

Code needs lots of work.  Like does pairing everytime, need to make that optional.

Also need to figure out where to split off the HID stuff from Root BT stuff.  ...

Plus it mainly prints lots of debug information.

WIP - I captured the USB packet information for the startup of a Bluetooth adapter.  I am now in the process of understanding the data that is being sent back and forth and have the device now partially configured.

Nothing works yet!

WIP - So far i am getting the basic values for 1 XBox 360 controller.  The device should handle up to 4 devices, but so far hard coded to only handle 1...
