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.

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.
