Then I'd have no way to communicate out the result, wouldn't I?

but it still's returns that error of yours on in case of other code garbage data - something like 0.00064

If it returning something different from no_echo - that means that it works, but data corrupted during transfer because of variable time slots.
You should switch off all interrupts during 1-wire communication.
