KW36: Why Write Response not sent for Write request?

Hi,

I am facing a issue in KW36 in sending Write response command. In my case is that my mobile app is trying to enable Client Characteristic Configuration Descriptor(CCCD) for a characteristic in my gattdb, but when the app sends Write Request for the writing the CCCD, the NXP stack doesn't send the Write Response sometimes for that.

Because of this my app disconnects from the KW36, 30 seconds after the Write Request is sent(I assume this is because of supervision timeout in phone/app)

I have attached the airtrace in which I have bookmarked my issue.

Regards,

Sai Kalyana Raman

Hi skalyan2@visteon.com‌,

Your HID device is mouse or keyboard, maybe the operating system took over the control of HID, so you can't operate it.
