v1.0.35

Summary

Dual Pool

The firmware now supports true Dual Pool mining, allowing the device to mine on two pools in parallel. Jobs from both pools are interleaved at the default job-switching interval (500 ms on BM1370 devices), without disconnecting or alternating Stratum sessions. Each pool receives a continuous stream of work and reports its assigned hashrate accurately. Dual Pool is supported on all Nerd*Axes — including the smallest NerdAxe with a single BM1366.

Under the hood, jobs from both Stratum connections are multiplexed into a single ASIC job stream using a Bresenham-based load-balancing algorithm. Returned nonces are routed back exclusively to the pool that provided the corresponding job.

The pool ratio can be configured in 1% increments. For example, an 80%/20% split allocates 80% of the hashrate to Pool 1 and 20% to Pool 2.

Note: At extremely low ratios (e.g., 99%/1%), a pool may attempt to reduce its difficulty below the ASIC’s minimum supported hardware difficulty. Mining continues to function correctly and all shares remain valid, but the pool’s hashrate estimate may become inaccurate. When this occurs, the UI marks the affected pool with an orange badge and a tooltip indicating that the ratio is too low.

Stratum Settings Reload

When you change and save Stratum settings — such as host, port, username, password, or the Dual Pool balance — the miner now reloads the configuration immediately and reconnects to the pools on the spot.
A reboot is no longer required.

Graphs switched to Chip Hashrate

In v1.0.34.1, the main hashrate display (top left, above “Expected Hashrate”) was already updated to use the more accurate Chip Hashrate. However, the graph still showed the older Stratum-share-based estimation.
This has now been unified: the graphs also use Chip Hashrate.

Because the new measurement stabilizes much faster, a 1-minute graph has been added as well.

Soft Power-Off

Holding both buttons for 5 seconds triggers a Soft Power-Off.
The miner disables the ASIC voltage regulator and suspends all running tasks, allowing you to safely shut down the device before disconnecting it from power.

HTTP Server Improvements

The ESP32 HTTP server now reliably terminates all HTTP connections on its own, preventing lingering or half-open sockets and avoiding socket exhaustion.
This should finally resolve the long-standing Web-UI unavailability issues that were reported repeatedly over the past several months.

v1.0.34.1

Version 1.0.34.1 – Summary

The 1.0.34.1 release introduces OTP protection, one-click firmware updates, multi-language support, and NerdQX and "6 phase" NerdOctaxe-Gamma (aka 6ph-Ocho 🤪) integration — along with numerous fixes and refinements for improved stability.

OTP

The release adds One-Time Password (OTP) security — a much more robust alternative to static web passwords.

The device now supports registering Authy or Google Authenticator via a QR code displayed on its screen, providing a lightweight, local second factor for the Web UI — without requiring TLS. During setup, you simply scan the QR code with your authenticator app. From then on, sensitive actions such as changing the BTC address or key settings must be confirmed using a 6-digit TOTP code.

Unlike fixed “admin passwords,” these codes are derived from a random secret using HMAC-SHA1 and time-based counters. They change every 30 seconds, cannot be reused, and are never exposed in the Web UI. This makes them immune to guessing, sharing, or accidental leaks.

While TOTP is not a full authentication solution for exposed setups (HTTPS with proper credentials is still recommended), it adds strong, pragmatic protection for LAN-only use — a real cryptographic barrier against trivial misuse over plain HTTP.

GitHub One-Click Update

Another major improvement is the one-click firmware update, which lets users easily select and install any available firmware version, including pre-releases. Once started, the update runs as a background task — independent of the HTTP server — for maximum reliability.

Previously, while firmware OTA updates already used a dedicated secondary partition for safety, the web interface (www) partition had to be updated directly from browser uploads. This was fragile: reloads, timeouts, or network hiccups could corrupt the partition and require recovery mode.

The new approach downloads the entire web partition in the background first, then applies the update in one atomic step — eliminating corruption risks almost entirely. As a result, web updates are now faster, safer, and far more robust.

This feature was a collaborative effort between @foXaCe and @shufps.

Language Support

Many thanks to @foXaCe, who contributed full translation support and localization for four different languages!

NerdQX

The release also introduces NerdQX support, which brought extensive internal refactoring. One of the larger changes was a revision of the display state machine and the power manager loop. The latter now operates with a fixed timer interval, improving the PID controller’s accuracy by ensuring a consistent sampling frequency.

NerdOctaxe-Gamma with 6 phases

The release also adds support for the new 6-phase NerdOctaxe-Gamma. Developed by @BitMaker-hub, this enhanced design introduces two extra power phases, resulting in improved thermal efficiency and much higher overclocking potential.

Miscellaneous

1.0.34 includes numerous bug fixes and stability improvements. Version 1.0.33 had to be withdrawn after reports of black screens, Wi-Fi crashes, and other issues — traced back to the ESP-IDF 5.3.3 toolchain. Reverting to ESP-IDF 5.3 resolved these problems, and 1.0.34 restores full stability.

From 1.0.33

That release brought major improvements to hashrate accuracy, monitoring, and stability. Hashrate is now read directly from the ASICs, providing instant precision. Additional enhancements include one-minute metrics, duplicate share tracking, extranonce subscription for better pool compatibility, and Discord block notifications and the BTC price ticker was fixed, and ESP-IDF was updated to 5.3.3.

v1.0.32.1

Summary

In v1.0.32, the OTA update process introduced overly aggressive hardware locking. This prevented the PID fan control from running during the update, which could potentially lead to overheating.

This issue has been fixed by:

Blocking concurrent flashing and I²C access during www.bin updates, while still allowing task switches after each page write, so the PID control loop can continue to run normally.

Powering down the buck converter during firmware updates, eliminating any risk of overheating. (Since the device reboots afterwards, this causes no side effects.)

⚠️ If you are updating from v1.0.32 using the web UI, please make sure the fan RPM is stable before starting the update. Updates performed with the web flasher are not affected.
