Note that you are replying to a thread that's over a year old.

So what debugging have you done to find what's occurring?

The clue is in the name: INVALID STATE

The code you posted shows what state it should be in.

err_code = 8 means , NRFX_ERROR_INVALID_STATE. could you suggest me the possible reasons of these kind of error generation.

I have Stepped into nrf_drv_twi_init(),

when nrfx_twim_init() function is call, in that,

below mentioned if condition is check and then control direct go to last line of these function and then,

app_error_fault_handler() function call.

if (p_cb->state != NRFX_DRV_STATE_UNINITIALIZED)
{
err_code = NRFX_ERROR_INVALID_STATE;
NRFX_LOG_WARNING("Function: %s, error code: %s.",
__func__,
NRFX_LOG_ERROR_STRING_GET(err_code));
return err_code;
}

The documentation for nrf_drv_twi_init() will list its possible return codes - you can find the numeric values in the source code.

Again, have you stepped into nrf_drv_twi_init() to see what is causing that error code?

So what err_code are you getting?

have you looked-up the meaning of that code?

Have you stepped into nrf_drv_twi_init() to see what is causing that error code?

Thank you so much for your reply.

sorry for late response.

i have debug the code its stuck some times in twi_init() function after following line.

err_code = nrf_drv_twi_init(&m_twi, &twi_config, twi_handler, NULL);
APP_ERROR_CHECK(err_code);

and if it some time come out from these function then it stuck in HardFault_Handler();

So what debugging have you done to find where, exactly, this is happening and what error, exactly, is occurring?
