Thanks for the link. That is a good overview over the different profiles. The app did not connect to the trackpad, which I think is no surprise as the trackpad only supports the HID profiles whereas the app only supports the SPP profile. The trackpad connects to various devices having an OS (tested ...

Hi everyone, as I couldn't find good information about that: what is the procedure to pair the ESP32 with a Bluetooth Classic HID device that requires a 4-digit PIN/passkey when pairing (such as my Bluetooth trackpad)? E.g. at what point and how am I supposed to enter the PIN? I only found this, but...

Any idea?

Could it be related to the pairing PIN? The trackpad normally requires to enter a PIN when pairing it. In my attempt I didn't come over any request to enter a PIN.

It is ...

Hi Roland,

I know it is a long time ago, but did you manage to pair your joystick with the ESP32? If yes, I (and probably many) would be very interested to know!

As far as I know, these apps only use Bluetooth SPP. Is that correct? Anyway, the app didn't connect to the trackpad, although it did connect to the Android phone itself. I could even use it as mouse input for the Android device. I feel it is very hard to find reliable information about the ESP32's ...

As I am planning to pair it with a Bluetooth mouse and receive movement data, I'm quiet interested in this! Did you manage to pair the ESP32 with the Bluetooth keyboard and receive key presses?

Hello everyone,

is it possible to pair an Apple Magic Trackpad (1. gen -> Bluetooth Classic 2.0) with the ESP32? How simple is that? Can I be sure it'll work?

I am asking as I had hard times finding any projects doing such things, even with Bluetooth keyboards.

Thank you in advance!
