Lights not blinking with nRF Blinky example

[Berry Blue]

I'm very new and trying to get the nRF Blinky example to work with an iPhone with an nRF52840.

I'm able to connect to the device and it seems to be reading and writing correctly to the LED but the light won't blink on the board.

It's not reading the button state from the board either.

Here is the output from the console on Xcode too. It looks like the board is getting read/written to but I'm not seeing the LED turn on

Hi Berry,

Have you programmed your nRF52840 DK with the right ble_app_blinky example for your board? For the nRF52840 DK you should use the project for PCA10056 which can be found under /examples/ble_peripheral/ble_app_blinky/pca10056/ in our SDK (latest version is v15.3). Remember to program Softdevice s140 as well.

Best regards,

Marjeris
