Hello Kenneth,

now code is working but when use

following code to transmit data but it's stuck to there and not transmit anything

uint32_t err_code;
uint8_t tx_data[] = {'a', 'b', 'c', 'd', 'e'};
const nrf_drv_twi_t twi = NRF_DRV_TWI_INSTANCE(0);
err_code = nrf_drv_twi_init(&twi, NULL, NULL);
APP_ERROR_CHECK(err_code);
nrf_drv_twi_enable(&twi);
err_code = nrf_drv_twi_tx(&twi, SLAVE_ADDRESS, tx_data, sizeof(tx_data), false);
APP_ERROR_CHECK(err_code);

it stuck at

err_code = nrf_drv_twi_tx(&twi,0x08, tx_data, sizeof(tx_data), false);

i'm using this example

"twi_master_using_nrf_twi_mngr"

Hi,

If you define DEBUG you should be able to find in app_error_fault_handler() what line of code is causing the error.

You need to add all twi configuration you can find the in the sdk_config.h twi examples in the SDK to your project. As an example I suggest to look at \twi_scanner and \twi_sensor examples.

Best regards,
Kenneth
