PicoMiteBTH.zip

Requirement Pico2-W or Pico Plus 2W (tested)

This is a standard PicoMite build, no VGA/HDMI/WEB support, except that is has Bluetooth LE support for various devices. I have tested using an Android app proxiOS which emulates keyboard and mouse and gamepad and all work properly.
It should work on any reasonably modern bluetooth keyboard  - must be Bluetooth LE and not Bluetooth Classic.

Please give it a go and report successes and failures

Cheers for the heads-up re: Android app proxiOS. Bit unusual that the Shift keys latch, like a Caps-lock but no big deal.

Edit: Oh, in the Trackpad screen, I can select my regular Android KB...Better

Now I have tested this keyboard, and it works OK

G'day Peter,
The only Pico device missing from my collection is a 2W of any flavor, got a couple on order and am looking forward to giving this a try when they arrive. If there is a possibility of getting it working on a Pico-1W I have a couple of them (somewhere)

Is there a plan to implement this in the HDMI/VGA firmware in the future or is this always going to be stand alone?

Can you also confirm you read my post in the RC thread regarding a possible bug in the I2C system?

Also still waiting for my "mate"   to return my CNC driver system to do some further testing of the stepper system, he borrowed mine "for a couple of days" 3 weeks ago now. And they wonder why I get grumpy.....

Regards, Lyle.

Does the trackpad and game controls on that keyboard work?. You can use the device(mouse and device(gamepad functions to test them.

My to-do list is looking a bit scary....grows every day.

I really like the look of that Mini Keyboard  

a few more tests I did on the mini keyboard







I can't get the trackpad to work, nor the mouse buttons.

Hi Peter,

Are you planning a command or function that regularly updates a list of detected Bluetooth devices (MAC address) in an array, along with their RSSI values? Something like a Bluetooth beacon scanner? That would be absolutely brilliant on a Pico with web support!

Hello, Peter
I thought I would try this mouse.











I don't really know how to test this, what device number does a BT mouse get?

what device number does a BT mouse get?

It will always get 2 unless already occupied, Keyboard 1, mouse 2, gamepad 3

Tested the mouse with this program:

, and it works.  

The middle button was the one that did not work on this mouse.

I tested the mini keyboard again. Wanted to see if the trackpad worked, and sure enough it worked. Used the same program that I used when I tested the mouse.

Just tested with this :



and it works nicely

I have tested version RC15 on the original Pico 2W, works fine.



Also tested on Pimoroni Pico LiPo 2 XLW, but does not work.

G'day,
Results of some testing for reference. Original RP Pico2W.
Keyboards listed as BlueTooth 4 or 5 seem to work fine, BlueTooth 3 (only one sample) does not.

Generic "Bewinner" 7-8" bluetooth keyboard, usually comes in "leather" folder for tablet.
Works well, big enough to type on, no backlight.



Generic "Micro" bluetooth keyboard. Do yourself a favour and spend a bit more on the Rii 518bt.
Works, too small for easy typing, has backlight.



Rii I4 dual mode keyboard / trackpad.
Works well, too small for easy typing, trackpad works, has backlight.



Rii RT518S dual mode keyboard / trackpad. Be careful, the K18 looks identical but is 2.4Ghz only.
Works well, big enough to type on, trackpad works, has backlight.



Rii 518BT keyboard.
Works well, key shape makes it fairly good to type on despite tiny size, has backlight.



The Rii keyboards are a bit more expensive than the generic stuff but seem to be pretty consistant. I have a few others and they survive abuse in the workshop quite well.
Only things that fail to work are the scroll wheel / scroll function and the CAPS LOCK LED.

Thanks again to Peter for implementing this, could prove to be very handy.

Regards, Lyle.

And those that didn't work:

Generic "Magnetic Bluetooth keyboard / touchpad", this shows as "BlueTooth 3"



And be wary of these, no function keys could make life difficult.



Regards, Lyle.
