RE: Nrf52832 resets after implementing Advanced buttons as HID device

Hi,

Sorry for the late reply. Have you set the optimization level to '0'? Debugging code with high optimization isn't always straight-forward.

Could you try setting a breakpoint at any instance of NVIC_SystemReset in your code?

Best regards,

Håkon

I have added DEBUG, but without any errors, i treset directly

Hi,

All your indexes and IDs look good.

Could you check the err_code return and see where it fails? This can be done by adding "DEBUG" to your preprocessor defines, and then you should end up in the app_error_handler (and file/err_code/line_number can be read out in m_error variable).

Best regards,

Håkon

I still don't quite understand what you mean. The following are the settings in my program. How do I modify it? Thank you very much.

Hi Jim,

What is the value of the index'es and REPORT_IDs?

USB REPORT_IDs (set in main.c::hids_init()) cannot be explicitly set to '0', and need to start at 1 and upwards.

However, in BLE-context, you should start at 0, so you need to separate these:

#define INPUT_REP_BUTTONS_INDEX         0                                           /**< Index of Mouse Input Report containing button data. */
#define INPUT_REP_MOVEMENT_INDEX        1                                           /**< Index of Mouse Input Report containing movement data. */
#define INPUT_REP_MPLAYER_INDEX         2                                           /**< Index of Mouse Input Report containing media player data. */
#define INPUT_REP_REF_BUTTONS_ID        1                                           /**< Id of reference to Mouse Input Report containing button data. */
#define INPUT_REP_REF_MOVEMENT_ID       2                                           /**< Id of reference to Mouse Input Report containing movement data. */
#define INPUT_REP_REF_MPLAYER_ID        3                                           /**< Id of reference to Mouse Input Report containing media player data. */

Kind regards,

Håkon
