Start a TWI transfer again

[Isabelle L.]

Hi, I would like to handle in the twi_event_handler the case when the p_event->type == NRF_DRV_TWI_EVT_EVT_DATA_NACK differently and not treat it as an internal error.

If there's a error with the TWI transfer that result from a DATA NACK I would like to try to do the same transfer again. Is there any built in way to do that?

Hi,

I don't really understand your question. Why can't you just restart the transfer from your twi_event_handler()?

switch(p_event->type)
    {
        ...
        case NRF_DRV_TWI_EVT_DATA_NACK:
            // RESTART TRANSFER HERE
            break;
        
        ...
    }
