I think you might have stumbled upon a bug in nrf_drv_config.h. First you need to make sure that GPIOTE is enabled by setteing:

#define GPIOTE_ENABLED 1

Then the number of low power GPIOTE events should be set to 6:

#define GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS 6

Hi, sorry for the late response. I don't think it violates the spec. Here is an interesting thread. And here is even an example on github that uses the ble-app-uart example with static passkey. It uses an old SDK and SD though.

Hi, Thanks a lot for your help, I made it running. I'm really sorry for disturbing you again. I have one more question. My device doesn't have any input or output capabilities. Is it against BLE specification to set a static passkey for a pheripheral device which doesn't have any capabilities?

Hi,

You will need to add "Man In The Middle" encryption when you set up the characteristics. Look up the rx_char_add() and change

BLE_GAP_CONN_SEC_MODE_SET_OPEN(&cccd_md.write_perm);

BLE_GAP_CONN_SEC_MODE_SET_ENC_WITH_MITM(&cccd_md.write_perm);

Have a look at the Glucose example, ble_app_gls, which uses MITM encryption to learn more. These are also informative post regarding MITM: link and link.
