Add suggest difficultly to ui

[Sledge0001]

Enhancement request:

Would be helpful to be able to place a suggest difficulty field to the UI to help improve the submitting of shares right from the stratum handshake to help expedite the submitting of valid shares to various pools.

[monster4866]

that would be nice

[skot]

We do suggest a fixed difficulty that's good for the bitaxe ("mining.suggest_difficulty", "params": [1000]). It's up to the stratum server if they want to use that or not.

What does being able to change this default get you?

[Sledge0001]

I don't see that being passed correctly to the pool at the miners startup / handshake.

Seems like the default diff being seen is 8192

[skot]

I copied that right out of the log for my bitaxe.. Can you post your log?

Which version of esp-miner are you on? There was a bug earlier

[Sledge0001]

Model: BM1366 Uptime: 32 seconds WiFi Status: Connected! Free Heap Memory: 179928 Version: v2.0.7 Board Version: 204

But also happens on a 201 board as well. It's on all 3 of the devices.

[Sledge0001]

What's wild is all 3 of the units start @ 8192 regardless.

[benjamin-wilson]

Public-pool? Other pools may not honor the suggest difficulty request

[Sledge0001]

Unique pool code however the previous v2.04 firmware code did seem to get honored. Also the code i am using does honor it with cgminer so I am not sure the pool code is the issue as 8192 seems like a specific number to start the diff at which would go against the start diff I have set on the pool side.

[skot]

can you connect your bitaxe USB-C to your computer and get the logs starting earlier in the cycle? The log should stream out over serial at 115200 baud. I think you'll see that mining.suggest_difficulty is being sent.

Same for me, with ckpool it starts at 8k then it goes to 10k and after 2-3min. The pool corrects this to 400-600

have 10 bitaxes, all the same, fw 2.0.7, boradv. 201-204

again, I'm pretty sure this is driven by the pool. If you get the full logs by the USB method I mentioned above we can check it out.
