Write packet to slave.

while (i2c_master_write_packet_wait(&i2c_master_instance, &packet) !=
        STATUS_OK) {
    /* Increment timeout counter and check if timed out. */
    if (timeout++ == TIMEOUT) {
        break;
    }
}

The module will try to send the packet TIMEOUT number of times or until it is successfully sent.

Read packet from slave.

    if (timeout++ == TIMEOUT) {
        break;
    }
