Should we need button_led_init function

[Minh]

Hi everybody

I am making a custom board which using ANCS (nrf51 sdk 9.0.0, softdevice 110 ver8.0.0). I saw on the original code have button_led_init() function to initiate LED and button. However, in my custom board, I do not using any button and LED. Can I remove this function for my application ?

By the way, How should I configure the memory in Keil in order to work with nrf51822 CEAA package both for ANCS and bootloader?

Thank you very much !!!

Yes, if your application doesn't use any LEDs or buttons, button_led_init() can be removed.

The DFU doucumentation in the infocenter shows how to configure the memory for the bootloader. The DFU example in the SDK should also have a memory configuration that you can use.

Thank you for your help. But, the function has : *p_erase_bonds = (startup_event == BSP_EVENT_CLEAR_BONDING_DATA); and without it, would it cause any problem?

No, it would not cause any problem to remove that code. BSP_EVT_CLEAR_BONDING_DATA will clear the stored boding data upon a button push during startup. If you don't have any buttons on your device, you will never use that feature.

when I remove that function, the device manage always delete the bond information when I restart the application as in this:

It causes my application require pair every time.

Here, I print the log when I put this function again.

It does not have "Successfully requested clear of persistent data" It does not make me sense. Could you please help me to solve it. Thank you.

If you set erase_bonds = false in main before calling device_mananger_init(..), do you still see the same problem?
