I can't see my ESP8266 worker at pool.vkbit.com or public-pool.io

[prosselloe]

Good afternoon.

I'm a technologies teacher and I want to introduce my students in Bitcoin mining.

In LeafMiner you suggest pool.vkbit.com, but when configured, I can't see my ESP8266 worker at it!
I tried also with public-pool.io, but I have the same problem.
I only can view my device at pool.nerdminers.org, but I prefer the last one.

Do you know where can be the problem? What can I do?

Thanks a lot.

Related issues:

• Change default pool to public-pool.io
• ESP8266 - not visible at pool (no valid shares submitted?)

[matteocrippa]

@prosselloe Happy to hear about introducing students to Bitcoin mining, the docs needs for sure a revamp as I recall the vbkit.com is not anymore supporting low difficulty.

For public-pool.io it should work if nothing outstanding has changed, at the end do suppose it uses the same version of pool.nerdminers.org.

Do you have by any chance any log out of public-pool.io?

I have no esp(s) next to me in this moment so it's a bit tricky to test it

Here you have an examlple:

Best regatds.

[matteocrippa]

It's a bit strange it continues to reconnect after submit, a this point something is happening in the response.
Need to check as soon I have a device around, but not earlier than next week

[g33xt4h]

Hi, i have the same issue. Tried it with 0.16 and 0.17 - here are the results with an esp8266 12-F and 0.17:

[matteocrippa]

I just merged the v/0.0.17 branch - #50
Let me know if it works anyhow better

[g33xt4h]

Thanks for the merge, i tested it again and sadly it did crash again.

[matteocrippa]

But does it happen as soon as the first job arrives or after a few time / jobs?

[g33xt4h]

It's everytime as soon as the second job is about to begin. First job is being transmitted ok.
This time the esp just hangs without a crash, so no exception code.

Seems a bit random if it crashes or hangs.

Thanks again for your work, i really appreciate it!

[matteocrippa]

Can be an overflow, esp8266 it's not the greatest in memory, btw when it crashes it later restarts no?
I need to check if it's not a force crash I had to trigger to make it work
