Hi Håkon,

1. yes, after add a keyboard descriptor afterwards; none of them work.

2. You are right. The root cause is that I indeed ignored set '.is_kbd' to true. After corrected it, both Consumer and Keyboard work as expected.

Maybe someone would meet same or analogous problem on nRF51822 platform, so I attach my code for reference.

Note: 4 key(s1, s2, s3, s4) events' define in reference code are as follows:

s1: input 14 chars (` 1 2 3 4 5 6 7 8 9 0 - = Backspace)

s2: music play/pause

s3: music volum down

s4: music volum up

devzone.nordicsemi.com/.../consumer_5F00_and_5F00_keyboard_5F00_nrf51822.c

my test environment as below:

SDK: nRF5_SDK_12.2.0_f012efa
SD: s130_nrf51_2.0.1_softdevice.hex
nRF DK: nrf51822 board
IDE: uVision V5.22.0.0
Code template: .\examples\ble_peripheral\ble_app_hids_keyboard

Peer side: the phone with Android 7.1

You can replace main.c in folder ble_app_hids_keyboard with attached file, and begin your own verification.

Thanks a lot,

QiangH

Hi,

Is the problem in your case that only the multi-media descriptor works, and if you add a keyboard descriptor afterwards; none of them work?

Note that the ".is_kbd" should be set when adding a keyboard descriptor. If it still fails, could you try this example (for SDK 11) and see if this works as expected? https://github.com/Rallare/nrf51_ble_app_hids_kbd_consumercontrol/blob/SDK11/main.c

Best regards,

Håkon
