NRF52: TWI High consumption when sleep mode

[Arepa]

Hello,

Recently I added TWI to my project it keeps a low consumption before call TWI functions to read or write after this my current consumption increases and keeps above 4mA when my device is in sleep mode

Current before TWI

sleep mode 5uA

standby 900uA 

RF active 10mA

Current after TWI

sleep mode 4mA

Standby 5mA

RF active 14-16mA

I tried to disable TWI after read/write function using the following code with no luck

	nrf_drv_twi_disable( &twi );
	nrf_drv_twi_uninit( &twi);
	
	// Nordic work around to prevent burning excess power due to chip errata
	// Use 0x40003FFC for TWI0.
	
	*(volatile uint32_t *)0x40003FFC = 0;
	*(volatile uint32_t *)0x40003FFC;
	*(volatile uint32_t *)0x40003FFC = 1;

	// Initialize the TWI with the event handler set to NULL. Makes the read
	// and write operations blocking. Must be done each time because  of the 
	// power off of the peripheral done above.
	 ret_code_t ret;
	ret = nrf_drv_twi_init( &twi, &twi_config, NULL, NULL );
	APP_ERROR_CHECK( ret );

my Initialization function:

   ret_code_t ret;

    ret = nrf_drv_twi_init(&twi, &twi_config, NULL, NULL);

    if (NRF_SUCCESS == ret)
    {
        nrf_drv_twi_enable(&twi);
    }

my read/write functions

//WRITE TWI
ret_code_t ret =0;	
	ret = nrf_drv_twi_tx(&m_twi_master, Address, (uint8_t *)&data, lenght, true);
      if (NRF_SUCCESS != ret)
       {
			return ret;		 	
       }		 
       
       
//READ TWI
       nrf_drv_twi_rx(&m_twi_master, Address, buffer, sizeof(buffer));

sdk_config:

I am using a NRF52 and SDK13 can someone give a hand with it

Hi, 

I Have the same Issue.

Any advice?

I had enabled others modules in my application, make sure if you are not using a module disable it, e.g UART on sdk_config.h
