NFC wake up functionality with BLE

Hi Andrew,

I would invite you to use infocenter when you are wondering what the different functions does and how to use them.

There it is described:

bsp_nfc_btn_init()

bsp_buttons_disable()

So you should not use bsp_buttons_disable() if you want to use a button to wake up.

You could use bsp_wakeup_button_enable()

Hi Martin,

Thank you for the code, two more questions:

1. err_code = bsp_nfc_btn_init(BTN_ID_SLEEP); do we need to initialize physical button before this call ie button with ID 0 uses to wake the chip?

2. What if we need both features: wake from the button and wake from NFC? do we still need this

err_code = bsp_buttons_disable();

or it can be safely removed. or we need to add something else

Please advise at your earliest convenience

Regards,

Andrew

Hi Andrew,

I have made an example with the ble_app_uart and wake_on_nfc as reference. devzone.nordicsemi.com/.../main.c

(sdk14.2 and softdevice s132)

Button 3 sets the device in sleep and nfc wakes the device up and then it starts to advertise again as usual.

(led 3 and led 4 works as led1 and 2 did in the wake on nfc example)

Hi Andrew,

I would like you to look at the bsp_event_handler in "Wake on NFC" and this thread for what you should add to your code.

Debug your code if you are having any issues.

Hi Martin,

Thank you for your reply. yes we are merging "ble_app_uart example" with "Wake up on NFC example". From the code what I posted in original post do we need to add/modify anything else?

Because "Wake up on NFC example" doesnt use softdevce and we want to make sure there is nothing else should be added/modify.

Can you please double check and advise

Thank you,

andrew

Hi Andrew,

Are you using the "ble_app_uart" as a starting point and then implementing " Wake on NFC example" ?

You could also look at the "Template Application" to test out how "wake on button press" works out and just change that with the "Wake on NFC"
