Hi. I am trying to send volume up and down hid commands to phone from KW36Z NXP board through BLE HID.
I am using Keyboard for report ID 1 and consumer for report ID 2.
For the first three seconds I am sending Volume Down command through report id 1(Keyboard usage page), and for the next three seconds I am sending Volume Up command through report id 2 (Consumer usage page).
However, for the first three seconds there is no volume decrease is seen on the phone, but for the next three seconds the volume gets increased.
If I try Keyboard and Consumer Hid separately it is working. But when I am using both as two reports, only consumer Hid is working.
Please anyone suggest any solution for this issue. Thanks in advance.
