Connecting 2nd esp32 as HID about esp_8_bit HOT 8 OPEN

You should have in mind that Esp_8_bit has a HID stack for classic bluetooth.
BLE and Classic Bluetooth are not compatible with each other.

Ok, I've been trying to replace the his stuff. But I can't find where in the code I can submit a pressed key to the emulator.
For instance, could you tell me where I can add a line so that as soon a a game boots a start button gets pressed?

Or maybe a simple gist to make an esp connect as a keyboard using that Bluetooth classic stack. I'd love to contribute to this project, but I need a little help to get started.

I'm not the author of this project. But as far as I can see, from the code, you should work with gui_hid(...) function which in turn handles Keyboard HID events for the console menu (that one used to change games) and also sends controller events to the current emulator by calling _emu->key(...).

Everything works as HID events from a bluetooth keyboard, including which is keycode 40 (same as pressing ).

I hope it helps you!

I forked this and added support for a hard wired NES controller which allows you to access the file tree with LEFT+SELECT.
It means that you need to solder in 5 leads from a classic NES controller to make it work thought...
If I get the time I might add in a second controller as well (unless someone beats me to it), it should be simple enough to extend it.

hi, I'm trying to add bluetooth joystick support , I have a universar joystick techmaster, tm.stk7005, when I connect the joystick to the emulator it is enter to the function hid(InputDevice* d, const uint8_t* data, int len)
in the switch the device enter here

        case 0x07: //test joystick bluetooth tecmaster tm.stk7005
                    {
                    printf("bluetooth tecmaster -> report: %02X\n",h[2]);
                    int sizeB = (h[2] >> 4) + 1;
                    int addrB = (h[3] << 8) | h[4];  // low bytes of address
                    h += 5;

                    int idB = (h[4] << 8) | h[5];
                    printf("tecmaster %04X:%02X read id is %04X\n",sizeB,addrB,idB);
                    dump_report(data,len);
                break;
                    }

but I don't know how to extract the data from the joystick. I can see how the len change when I move the stick or I press some buttons.
can any help me?

Here is something fresh out of the press...

I have not tested it myself but looks useful to those who wish to keep things wireless :)

Is there any possibility to integrate wireless connection between 2 esp32 for the emulator via ESP-NOW? If yes, where do I need to enter the code I've written for receiving input?
