unwanted Signal on Port Pin 0.7

[ruetten]

Hello,

we have an custom made board with a module from raytec MDBT42q.

Our application based on the nus example.

On port 0.7 we have a led.

It seems, that there is maybe a debug function in the softdevice stack??

  log_init();

  nrf_delay_ms(500);

  timer_init();
 //  uart_init();
  buttons_leds_init();

#ifndef NO_BLE
  db_discovery_init();
  power_management_init();
  ble_stack_init();
  gatt_init();
  nus_c_init();
  scan_init();
  scan_start();
#endif

  SysTick_Config(SystemCoreClock / 1000);

  InitIo();

  SetPower(0);
  SetPower(1);

  LedCheck(1);

  // Enter main loop.
  for (;;) {

    // Statemachine();

    //  idle_state_handle();
  }

All parts of our code are deactivated, but the led is still blinking on a long aperiodic time.

Any Idea from wich part of the stack this came from ?
