I cannot get "app_usbd_hid_hid_user_evt_out_report_ready" interrupt in "hid_bulk_ev_handler"

Sending data will receive an "APP_USBD_HID_USER_EVT_IN_REPORT_DONE" interrupt, but receiving will not receive an "APP_USBD_HID_USER_EVT_OUT_REPORT_READY" interrupt

Sorry, Google translation error.

I mean, can't i read it in "case APP_USBD_HID_USER_EVT_OUT_REPORT_READY:"?

I don't understand the question, maybe you can find what you need from one of the examples?

Can your problem be related to interrupt priority?

Can't it be interrupted?

Hi,

I believe that you should be able to receive the data in APP_USBD_HID_USER_EVT_OUT_REPORT_READY by using:

[…]

uint8_t * recv;

size_t siz;

recv = (uint8_t *)app_usbd_hid_generic_out_report_get(app_usbd_hid_generic_class_get(p_inst), &siz);

data[0] = recv[0];

[…]

I can get the number of bytes received with the following code.

uint8_t rec = nrf_usbd_epout_size_get(NRF_DRV_USBD_EPOUT3);
NRF_LOG_INFO("%d", rec);
