[quote user="William.wei"]i also did two services, and it works well. but one service example had some drive problem;[/quote]

Great, I am happy to hear that this resolved your issue! :)

[quote user="William.wei"]for the similar ticket in the devzone, no one has the answer for this problem, so i raised this ticket.[/quote]

I am not sure what you mean by this - did you make the ticket in order to make it a publicly known fix?
If so, we will need to make this ticket public, or to create a new public ticket, in order for it to be viewable to everyone, if this is what you mean.

Best regards,
Karl

Hello again, William

Thank you for your patience with this. The summer holidays have begun here in Norway, and DevZone is therefore operating with reduced staff for the time being. Sorry for any inconvenience this might cause.

I see that multiple other users have had similar issues when merging the keyboard and mouse example. It seems that separating the mouse and keyboard into two separate HID services resolves this issue.
Could you try this as well, and see if it resolves your issue?

Best regards,
Karl

Hi Karl,

sorry i was on business trip and missed this ticket.

yes, of course i can provide the entire project, just simply replacing the main.c by main_.c should be OK.

this is based on keyboard project ----examples\ble_peripheral\ble_app_hids_keyboard\pca10056.

devzone.nordicsemi.com/.../ble_5F00_app_5F00_hids_5F00_keyboard.7z

Hello William,

[quote user="William.wei"]if you can help to try this main.c[/quote]

Sure, I can try it. Is there any other changes I need to do, than to just substitute in the provided main file into the ble peripheral keyboard example? No changes to the sdk_config or project configurations?
In general it would be best if you could provide the entire project in a zip when asking us to perform a test, to eliminate potential sources of error (such as a project configuration being different between our two projects, or similar).

[quote user="William.wei"]if there is driver error, why erase chip can help to solve this issue[/quote]

I've learnt that there are many things that could cause such behavior of drivers in windows, unfortunately. It could be so easy that the reboot and reopening of the COM port is enough for it to resolve the issue, for example, or it could require a reinstall of the driver entirely.

Please also show me the 'driver' and 'details' tabs of the properties you have sent screenshots of.

Please see my other question from my previous comment as well:

[quote user="Karl Ylvisaker"]I too would think that this might be a Windows driver error - which Windows version is the customer / you using?[/quote]

Looking forward to resolving this issue together!

Best regards,
Karl

Hello,

[quote user=""]third, i use command nrfjprog -e to erase all the flash and reprogram the DK board(52840DK), find out that every thing is fine,[/quote]

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.

[quote user=""]

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.

[/quote]

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

[quote user=""]you can see attachment "main_1.c" ,and tested, it turned out that pc driver error.[/quote]

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
