}SDK14.0+NRF52832: firstly I init the passkey in the function gap_params_init as above.I want to change the passkey and can save the new passkey to flash, but when I input one new passkey and call the function sd_ble_opt_set again, error occurs（err_code=7）.
void update_secon_code(uint8_t new_passkey[])
{
uint32_t err_code = NRF_SUCCESS;
m_static_pin_option.gap_opt.passkey.p_passkey = new_passkey;
err_code = sd_ble_opt_set(BLE_GAP_OPT_PASSKEY, &m_static_pin_option);
NRF_LOG_PRINTF("update_secon_code:err=%x\n", err_code); //return err_code=7
APP_ERROR_CHECK(err_code);
}
My question is how to change the passkey?
