Hello Nordic Experts,
I'd like to add the usb hid composite to one of BLE examples. I followed link below and combined the example usbd_hid_composite with ble_app_blinki_c.
The BLE part works fine, but I use Bus Hound to monitor the USB and there is no sign of any USB device. Can you please help me understand what is wrong here.
I just copied/pasted all definitions&declarations from usbd_hid_composite (excluding CLI interface) to the ble example, and added all required path/files to the project. I then set
#define USBD_POWER_DETECTION false
and in sdk_config.h,
#define APP_USBD_CONFIG_POWER_EVENTS_PROCESS 0
#define POWER_ENABLED 0
#define USBD_ENABLED 1
#define APP_USBD_ENABLED 1
#define APP_USBD_VID 0x1915
#define APP_USBD_PID 0x520B
#define APP_USBD_HID_ENABLED 1
#define APP_USBD_HID_KBD_ENABLED 1
#define APP_USBD_HID_MOUSE_ENABLED 1
This is my main
int main(void)
{
ret_code_t ret;
static const app_usbd_config_t usbd_config = {
.ev_state_proc = usbd_user_ev_handler,
};
log_init();
ret = NRF_LOG_INIT(NULL);
APP_ERROR_CHECK(ret);
ret = nrf_drv_clock_init();
APP_ERROR_CHECK(ret);
nrf_drv_clock_lfclk_request(NULL);
while(!nrf_drv_clock_lfclk_is_running())
{
/* Just waiting */
}
ret = app_timer_init();
APP_ERROR_CHECK(ret);
ret = app_timer_create(&m_mouse_move_timer, APP_TIMER_MODE_REPEATED, mouse_move_timer_handler);
APP_ERROR_CHECK(ret);
init_bsp();
//init_cli();
ret = app_usbd_init(&usbd_config);
APP_ERROR_CHECK(ret);
app_usbd_class_inst_t const * class_inst_mouse;
#if CONFIG_HAS_MOUSE
class_inst_mouse = app_usbd_hid_mouse_class_inst_get(&m_app_hid_mouse);
#else
class_inst_mouse = app_usbd_dummy_class_inst_get(&m_app_mouse_dummy);
#endif
ret = app_usbd_class_append(class_inst_mouse);
APP_ERROR_CHECK(ret);
app_usbd_class_inst_t const * class_inst_kbd;
#if CONFIG_HAS_KBD
class_inst_kbd = app_usbd_hid_kbd_class_inst_get(&m_app_hid_kbd);
#else
class_inst_kbd = app_usbd_dummy_class_inst_get(&m_app_kbd_dummy);
#endif
ret = app_usbd_class_append(class_inst_kbd);

scan_start();
if (USBD_POWER_DETECTION)
{
//ret = app_usbd_power_events_enable();
APP_ERROR_CHECK(ret);
}
else
{
NRF_LOG_INFO("No USB power detection enabled\r\nStarting USB now");
app_usbd_enable();
app_usbd_start();
}
// Turn on the LED to signal scanning.
bsp_board_led_on(CENTRAL_SCANNING_LED);

}
Thanks
