Esp32 HID Host cannot connect to classic Bluetooth game pad and keyboard
Posted: Tue Sep 24, 2024 7:26 am
i've been trying to use a esp32 wroom as hid host to read data input from bluetooth game pad or keyboard so i can use them as a physical interaction input to my projects. But it seems like the connection always fails. I don't know if it is caused by incompatibility between esp-idf bluedroid and game pad hid profile or it is something else? The following is the log of the whole process:
My keyboard and game pad has the exact same error log except they are scanned as different device.
