Be careful about temps / cooling! Especially when you start attempting sending those chips commands. Don't want them to start hashing and immediately going up in flames. Tongue

But Skot knows much more than myself about this (how / when they start hashing / getting hot).

It's just that I've experienced (as a customer) finished mining products hashing even when not getting supplied any data at all (not sure what they were doing - again: as a customer).
Just saying I've encountered it and I'm not sure whether that was just the 'idle behavior' of those chips (older stuff, not BM1397 for sure) or firmware-related.

Great advice. Coding an ESP Miner to test it correctly, is a pain. I hope to use ESP-IDF Version 5 (std) with ESP-Rust 1.66 (std) and code some minimal rust-based ESP Miner for testing.

The biggest problem i have encountered is the support and community for xtensa-esp32s3 using rust is minimal or non-existent at best. i have tested some simple ESP miner code on my ESP32-S3-WROOM-2-N32R8V Dev board that i have and it runs fast but that is without it communicating or mining on BM1397 chips. Next step will be to try adapt this minimal testing code to communicate and mine on BM1397 chips and use it on the onboard ESP32-S3-WROOM-1-N16R8V on my ESP mining board.

that's a lot of grunt work to be done.
