Hi,
I'm using nrf52840 DK to connect and receive usbhid message with the message size > 64 bytes (examples 343 bytes), so the message is divided to multi packages. I modified usb_hid_generic example, but I just received 2 packages. That is some change in my code:
#define REPORT_IN_QUEUE_SIZE 63
#define REPORT_OUT_MAXSIZE 63
#define REPORT_FEATURE_MAXSIZE 31
#define ENDPOINT_LIST() \
( \
HID_GENERIC_EPIN, \
HID_GENERIC_EPOUT \
)
static void hid_user_ev_handler(app_usbd_class_inst_t const * p_inst,
app_usbd_hid_user_event_t event);
#define USBD_GENERIC_REPORT_DESCRIPTOR { \
0x06, 0xD0, 0xF1 , /*USAGE_PAGE (FIDO Alliance) */ \

0xa1, 0x01 , /* COLLECTION (Application) */ \
0x09, 0x20 , /* USAGE (Input Report Data) */ \
0x15, 0x00 , /* LOGICAL_MINIMUM (0) */ \
0x26, 0xff, 0x00 , /* LOGICAL_MAXIMUM (255) */ \

0x95, 0x40 , /* REPORT_COUNT (64) */ \

}

switch (event)
{

size_t recv_size;
uint8_t* recv_buf;
recv_buf = (uint8_t *)app_usbd_hid_generic_out_report_get(&m_app_hid_generic,&recv_size);
NRF_LOG_INFO("received data length:%d", recv_size);
NRF_LOG_HEXDUMP_INFO(recv_buf, recv_size);
break;
}
case APP_USBD_HID_USER_EVT_IN_REPORT_DONE:
{
NRF_LOG_INFO("APP_USBD_HID_USER_EVT_IN_REPORT_DONE");
bsp_board_led_invert(LED_HID_REP_IN);
break;
}
case APP_USBD_HID_USER_EVT_SET_BOOT_PROTO:
{
UNUSED_RETURN_VALUE(hid_generic_clear_buffer(p_inst));
NRF_LOG_INFO("SET_BOOT_PROTO");
break;
}
case APP_USBD_HID_USER_EVT_SET_REPORT_PROTO:

break;
}
default:
NRF_LOG_INFO("UNDEFINDED_EVENT %d", event);
break;
}
}
What is problem in here?
Thanks!
