Error on GPIO READ or CLEAR or SET after BLE init

[Ashok]

Hi,

Once I enter into BLE mode I am not able to read any gpios(nrf_gpio_pin_read) also I am not able to set any gpios (nrf_gpio_pin_set).

Below is my example

uint8_t data;
uint8_t len;

uint32_t status = nrf_gpio_pin_read(PIN_NO); //Error  here
if(status)
  data[0] = 'O';
else
  data[0]  = 'F';

len = 1;

err_code =  ble_nus_send_string(&m_nus, data,  len);
if(err_code != NRF_ERROR_INVALID_STATE)
{
    APP_ERROR_CHECK(err_code);
}

same error on below

void nus_data_handler(ble_nus_t * p_nus, uint8_t * p_data, uint16_t length)
{
    if(p_data[0] == 'O')
         nrf_gpio_pin_set(LED_PIN); //error   
    else
         nrf_gpio_pin_clear(LED_PIN); //Error
}

Please do need full

Thanks

The function nrf_gpio_pin_read either returns 0 or 1. There is no other possible outcome from this. What did you mean that you cannot read from the gpios? Does it return anything else?

Sorry for typo Error means my controller resets

That is very wierd, and you have narrowed it down that it is caused by reading gpio's? What version of hardware are you using?
