A teensy plus bluetooth plus lipo-usb loading module would need a lot space.
The blend micro I have also has bluetooth on it but would require the lipo loading module.
In the end I have edited my design a tiny bit for being able to place a "Adafruit Feather 32U4 BLE" in it.
This board has everything on it for bluetooth and for loading the lipo battery.
All the 3d printed parts are ready, I just hadn't enough time to soldering/assemble all the stuff and start programming. :ashamed:

Some progress...

This is a photo of the bluetooth version of my snap on device.
I had to resize the base part a bit (and its attached parts) to fit in the "adafruit feather 32u4 ble" Arduino board.
Everything is soldered/assembled and should work, hopefully.
A battery can be attached to the back of it. I already designed a casing but for programming I'll stick to power via usb for now until I figured out how to tell the board to power on/off when a battery is connected and have everything else from my teensy-usb firmware version adjusted for this board to work via bluetooth :wink:

Got the code converted (and reduced in size, hitting 98%) to work on the adafruit feather 32u4 ble, finally.
I had to switch some libraries to get it working and I wasn't aware of the reduced memory of the feather 32 (32kbytes) compared to the teensy 3.2 (64kbytes) so it was more work than I have expected.
Using the teensy with a bluetooth module instead would have been a lot easier...

USB mode works fine already.

Bluetooth is working somehow, maybe. I can enable it on the feather and connect my phone (old android) with it, but can't receive any keyboard input. This may because of it is acting as a "ble keyboard" and not a "bluetooth keyboard".

I can't get it to connect to the Titan Two via bluetooth.
@J2kbr:
1. Is there anything special I have to do for the pairing, some special mode or should it find the device like my phone does ?
2. Will "ble hid keyboard" be supported by the Titan Two ? - There seems to be a difference to bluetooth keyboards, but I couldn't find more information about that.

The generic HID support for Bluetooth devices is not yet implemented (currently only via USB). This implementation is one of the priorities I have at the moment and it shouldn't take longer to have available for use. ;)

I bought Scachi's USB snap-on device, the black/green one and it's really awesome to use! I'm impressed by the stability of the device, i can use and configure the buttons without any move of the device. And the back buttons are perfectly positioned and easy to use with a finger. Nice work :smile0517:
Console tuner since my 1st controller.

Any updates on this ? Almost a year later and still no BLE HID. I would love to use my ble version wireless finally.

Yes, I know -- sorry. Currently I am working on the support for Wii U and Wii consoles. Finishing this will get back to the Bluetooth HID.

I lost my converted code for adafruit feather 32u4 ble because of a hard disk crash. So I need to do the convertion again. Before spending time doing that... Is BLE HID working already ?
