APP_USBD_HID_USER_EVT_OUT_REPORT_READY trigger only one time with USB OTG

[phamquocvinh]

Hello,

I'm having a weird problem while doing a communication between nRF52840( perpherial device ) with USB OTG ( STM32 ).

I'm trying send out the data from USB OTG -> nRF52840 via HID OUT endpoint.

I only get the event APP_USBD_HID_USER_EVT_OUT_REPORT_READY one time and get the data by API app_usbd_hid_generic_out_report_get

From second time, I can't get APP_USBD_HID_USER_EVT_OUT_REPORT_READY  any more?

Any require ment to clear the buffer?

I know that I have to call 

while(1)
{
app_usbd_event_queue_process();

}

but it doesn't work

Any idea?

Hi

There shouldn't be any requirement to clear the buffers explicitly, no, but I will check with the developer to be sure. 

Are you basing your code on one of the examples in the SDK?

If yes, which one? 
And what is the SDK version you are using?

Best regards
Torbjørn

Hi Ovrebekk,

Yes, I'm basing on the app_usbd_hid_generic example. 

I'm using the latest SDK nRF SDK v16.0.0

Hi

I discussed it with the developer, and he asked if you have been able to confirm in some other way that the OUT transaction is being sent from the host?

Do you have access to any USB traffic logs that could show the bus activity?

Best regards
Torbjørn

[phamquocvinh]

Yes. I run the same code to send OUT transaction, first and second after 1 second.

nRF chip only always get FIRST transaction. From the second transaction, it won't fire the event anymore

I'm buying a USB analyzer to monitor the bus

When I send to OUT transation on PC ( Windows), everything works well. I think there is a problem with bus of USB OTG but don't know why it got the packet one first time.
