ESP Miner Firmware v2.1.8: Fix for Possible Overheat If WiFi Disconnects

Source

ESP Miner, the renowned open-source miner firmware designed specifically for BitAxe v2+, has released a crucial update to its firmware, version 2.1.8. This update addresses a significant overheating issue that could occur if the WiFi connection drops, ensuring safer and more reliable operation for all users.

The problem first surfaced with the 2.1.7 update, where users began reporting potential overheating incidents when their devices lost WiFi connectivity. Public Pool, a notable entity within the mining community, issued an urgent recommendation: "If you've updated your Bitaxe to 2.1.7 there is a possibility of overheating if the WiFi disconnects. Please update to 2.1.8."

The rapid response and fix were lauded by community members, including @skot9000, who praised both the users who reported the issue and Public_Pool_BTC for their swift action in identifying and resolving the fan control bug. The new firmware release, version 2.1.8, not only mitigates the overheating risk but also introduces several other enhancements and optimizations.
