Nrf 51 BLE HID with Feature and Output reports example?

[VoidGreen]

Hi,

Is there an example available for Nrf51822 BLE HID (nrf5 SDK v11) with Feature and Output reports? I've added an output HID report to HID mouse example from SDK and Windows recognize it. But when I try to write a report to device it fails with a error like "ERROR_INVALID_PARAMETER 87 (0x57) The parameter is incorrect.".

Thx for your help

The hid keyboard application example in the SDK has Feature and Output reports.

Yes, but this output report is for Num/Caps/Scroll locks and Windows denies writes to standard keyboard reports. Regarding feature report it is present in descriptor (rep_map), but it is not set in ble_hids_init_t hids_init_obj; structure and this looks a little bit weird too.

You are correct, this looks like a bug in the hid keyboard example application and has been reported internally. I managed to find an example that uses feature report. This was made for SDK6.1, but you can still use it as a reference for how to implement feature report. The file is found here: main.c.
