Another interessting concept. 3rd party controller pairing is already available there. Thanks for posting.

Ah right, got it. I noticed the other day on Wikipedia that the Joystick port can somehow used for output as well, but I didn't have that in my mind anymore. Thanks for clarification.

The Doctor itself is answering to my thread...wow ? Cool idea. The new VCS joystick didn't came up in mind...but this is actually exactly what I'm thinking in a 2nd or 3rd iteration of the "CX2BTLE"-Adapter. My approach was to upgrade some of the CX40 replicas with the integrated ESP32 BT-Module (in my figueres the _B-Board) - But using a "off-the-shelve-BT-stick" is even better. Regarding polling: If I understand Bluetooth-LowEnergy correctly, there is no need for polling all the time. The "sensor"-device (BTLE Clients) actively sends data to the receving end (BTLE Server) if there are any data to transmitt (in our case, e.g. button is pressed) I had a similiar idea regarding tablets / phones. Something like a "Touch-screen input"... but I think this will be a rare requirement. But if the _A-Module is working fine, there is no reason why this shouldn't be possible. Not sure about a valid use case for connecting modem, printer etc to the joystick port... or did I missunderstood something? Best regards

Interesting! Thanks for posting. I'll check that out.

Dear community, first of all, happy new year to everyone. I hope you already started well into the new year. Recently, I was looking for some "easy" Bluetooth / Atari CX40 Joystick adapters and found @tschak909's post. As it seems, currently there are no such solutions available. (I hope this is still applicable?) So, I've been thinking about it for the past few days and decided to sketch a very high-level concept what could be done. I would like to avoid any design faults (and even maybe someone would like to participate somehow), so it’s publicly available on GitHub: https://github.com/cwanized/CX2BTLE/wiki/Introduction (please keep in mind, this is a first draft about some ideas. Spelling etc. not checked yet?) I am not experienced just yet with the ESP32 (in my former company I used to use Microchip PIC/NEC Microcontroller), but what I have seen so far, it should be pretty straight forward. (Astonishing what they have integrated in such a small chip). Furthermore, it would be nice if it is possible to support additional devices and different peripherals (e.g., Sega Controllers etc). Currently I am not sure if this is doable, but if I am going to design a PCB, I should keep these devices /peripherals in mind. Any thoughts? Great idea or just a waste of time? Best regards Chris
