I am trying to get my ESP32 pair with a Bluetooth Classic 2.0 trackpad (generally recognized as Bluetooth mouse on Windows/Linux) using the official esp_hid_host example.
So, I:
- followed Get started guide
- built and flashed the example
- opened a monitor
- put my trackpad into pairing mode
- reset the ESP32

- using the master branch of esp-idf --> the same result
- with v4.4.2 in menuconfig: set Component config --> Bluetooth --> Bluedroid options --> Secure Simple Pairing to DISABLED --> results in a build error (/home/user/eclipse-workspace/esp_hid_host_v442/build/../main/esp_hid_gap.c:426: undefined reference to `esp_bt_gap_set_security_param')
- older versions such as v4.3.1 or v4.2.4 (with their included example code of esp_hid_host) result in build errors even in default config (../main/esp_hid_host_main.c:131:54: error: 'esp_hidh_gattc_event_handler' undeclared (first use in this function); did you mean 'esp_hidh_event_data_t'?)
