BLE hid keyboard with mouse project pc driver error

[William.wei]

hi support team,

i have a wired problem that i can't explain to customer:

first, i test this project "nRF5_SDK_17.0.2_d674dde\examples\ble_peripheral\ble_app_hids_keyboard" and every thing is fine,

second,and customer want to merge mouse into this project so i did it, you can see attachment "main_1.c"  ,and tested, it turned out that pc driver error.

third, i use command nrfjprog -e to erase all the flash and reprogram the DK board(52840DK), find out that every thing is fine,

so i guess may be this is windows driver problem, but i don't know why.

could you please help about this? i really don't know why.

main_1.c

Regards,

William.

Hello,

third, i use command nrfjprog -e to erase all the flash and reprogram the DK board(52840DK), find out that every thing is fine,

Could you elaborate what you mean by this - does doing an erase all operation fix the driver issue with windows..?
That would be very strange indeed.

so i guess may be this is windows driver problem, but i don't know why.

could you please help about this? i really don't know why.

I too would think that this might be a Windows driver error - which Windows version is the customer / you using?

you can see attachment "main_1.c"  ,and tested, it turned out that pc driver error.

Which driver error is given? If you go into device manager, and click properties on the connected device with the error, which driver is it using?

Best regards,
Karl
