I have a question.
I bought this product to study the block chain.
So I deployed serial communication directly without using cgminer.
First, finding nonce was successful. (Ref. bm1385 datasheet document)
But there are no results when searching for a block without nonce.
So I don't know when to send a signal to find the next nonce.
How do i know that the work of finding nonce is finished? (without timeout)
