I would also note here for others with similar issue that I had trouble with interrupt level. API call is making level 2 interrupt. I called it from gpiote interrupt routine, which is level 1 interrupt. So, I've got HardFault because of it.

It has been proven that more than one HID over Gatt service can be implemented. Note that it is 2 different services not one service with different reports.

It seems to me that Håkon's first answer below answers the original question here, so to clear up this question, I'd be happy if you could accept that answer, by clicking the button below it. :-)

Hi Peeter,

It sounds like there's an issue with your HoGP setup. If you go to: www.nordicsemi.com/.../register

Register a user here, login, then click on "Register new case". Here you can input a new case (and upload files), which will ofcourse be handled confidentially.

Best regards Håkon

Hi, yes I have managed to get two HID services to run on the device. I can see the separate HID devices with MCP. I also managed to get the both HID devices connected with Linux. I can pair with the device and connect. I am not much allowed to tell about the application in public. So, I try to explain my issues without naming industrial specifics.

It looks like my SDK key is not enough for haveing the code for Smart Remote 2 reference design.

Now I have 2 HID services and with the 2nd service I have strange issue: sd_ble_gatts_hvx() will end in HardFault_Handler(). 1st service is running well, the same issue does not appear with it. If I turn off the 1st service and have only 2nd service in my device, then it ends in HardFault_Handler() aswell. I have spent quite a lot of time to verify that all the parameters given to the sd_ble_gatts_hvx() are reasonable.

At the moment my code is pretty much of fusion of nrf6310/s110/ble_app_hids_keyboard and mouse.

Hi Peeter,

It is possible to have more than one HID service on one device, such as a mouse+keyboard combo. If you look at the nRFready Smart Remote 2 reference design, this uses more than one HID descriptor.

Can you elaborate on what your application is?

Best regards Håkon
