Zephyr HID mouse and keyboard sample

[Marcelo Aleks]

I need to implement a mouse and keyboard (combo) HOG device.

There are mouse and keyboard samples, but may I integrate them in just one?

Is there any samplecode?

I have already write the reports data describing mouse and keyboard, each one with its REPORT ID, but it is not working...

Thanks in advance!

Hi Torbjørn,

  I really do not understand what is happening.

  See, below is my report map:

    0xC0,       // End Collection

When i connect the device (named SAFE), the OS (Linux) got 2 new devices :

dmesg:

[ 1556.472958] input: SAFE Keyboard as /devices/virtual/misc/uhid/0005:0000:0000.0050/input/input176
[ 1556.473985] input: SAFE Mouse as /devices/virtual/misc/uhid/0005:0000:0000.0050/input/input177

From btmon, i am intending to send messages to mouse using '2' as preamble so i can verify:

> ACL Data RX: Handle 71 flags 0x02 dlen 12                                                                                                                 #108 [hci2] 6.972096
      ATT: Handle Value Notification (0x1b) len 7
        Handle: 0x0024
          Data: 0200000000
> ACL Data RX: Handle 71 flags 0x02 dlen 12                                                                                                                 #109 [hci2] 7.021703
      ATT: Handle Value Notification (0x1b) len 7
        Handle: 0x0024
          Data: 0201001400  <----- (button pressed dx=0, dy=20, wheel=0) ok!
...

But it is being interpreted as keyboard output,  echoing only characters....

Do you have any clue?

Thanks, Aleks

Hi Aleks

Are you able to share your sample with me so I can try to reproduce the issue on my side?

If you don't want to share your code in a public case just let me know, and I will make the case private.

Best regards
Torbjørn

Good morning [perhaps afternoon !-) ]  Torbjørn!

  I had success!!!

  My mistake was that I do not created a second characteristic for the mouse. Now everything is working pretty well!

  I really appreciated your help, Thank you!!!

That is great news Aleks!

The best of luck with your project
