Sorry for not being more specific in my previous comment. You need to make sure the previous transfer is finished before the next is executed. This can be achieved either by adding the while loop inside your read and write functions, after each call to nrf_drv_twi_rx\nrf_drv_twi_tx, or by checking the while loop before calling your read/write functions (except the very first call). Which solution is best for your application depends on how often you do twi read/write, and if there are other tasks that can be executed while waiting for the transfer to finish. If you go for the second option, you will still need to include the checking of the while loop between tx and rx in your read function.
