Initial Setup

First-Time Configuration

1. Automatic WiFi Connection: Upon power-on, the device attempts to connect to the previously configured WiFi network. If connection fails after 15 seconds, it automatically enters configuration mode.

2. Access Point Setup: Search for the free access point named nmap-2.4g (no password required).

3. Configuration Interface:

   • Mobile devices: You will be automatically redirected to the configuration page
   • PC/Desktop: Navigate to 192.168.4.1 in your web browser

4. Parameter Configuration: Configure your mining parameters following the on-screen instructions. Note that higher UI refresh values result in increased hash rates, and hash rates also improve when the display is turned off.

5. Accessing Configuration: You can return to the configuration page at any time using the button controls.

6. Saving Settings: After clicking Save, allow 10-15 seconds for the process to complete. Do not manually reset the device; it will restart automatically.

Manual Configuration Mode

For single button boards:

1. Long press the boot button

For dual button boards:

1. Long press the user button

2. Follow the First-Time Configuration steps.

Firmware Installation & Updates

Using NMMiner Flash Tool

Step 1: Open the NMMiner Flash Tool in Chrome or Edge browser.

Step 2: Select your board model and initiate the firmware update. The tool will automatically:

• Download the latest firmware version from GitHub
• Configure flash parameters for your specific board

Note 1: If you're simply updating existing firmware, the above steps are sufficient. For first-time installations, firmware activation is required.

Note 2: If you lose your license, re-flash your device using the NMMiner Flash Tool to receive a new license automatically.

Firmware Activation

Step 1: After flashing the firmware, obtain your license following the on-screen instructions.

Step 2: Copy the license string into the license code field and click the activation button. Successful activation will display a confirmation message.

Step 3: For first-time installations, configure basic settings as shown below. Alternatively, you can configure these settings later using the button controls.

Step 4: Your miner is now ready to use!

Mining Pool Configuration

Due to limited on-chip resources, some high-difficulty mining pools may reject connections from ESP32-based miners. The following pools support low-difficulty stratum connections suitable for this hardware:

Bitcoin (BTC)

• stratum+tcp://solobtc.nmminer.com:3333 - Home page
• stratum+tcp://au.solobtc.nmminer.com:3333 - Home page

DigiByte (DGB)

• stratum+tcp://dgb-stratum.solominer.net:3333 - Home page

Monitoring & Management

Web-Based Monitoring

Access the web monitoring interface by navigating to your miner's IP address in a web browser.:

HTTP API

NMMiner firmware exposes a REST API on port 80 that can be used to query device status, read and update settings, and control the device programmatically — no authentication required.

Category	Endpoints
Discovery & Status	GET /probe · GET /alive · GET /api/system/info
Settings	G/P /api/setting/network · mining · time · preference · market · weather
Market Data	GET /api/market/pairs
Weather	POST /api/weather/refresh
System Control	POST /api/swarm/find · POST /api/system/restart
Screensaver	GET /api/update/screensaver/preflight · POST /api/update/screensaver

Each device also serves an interactive API documentation page at http://<device-ip>/api-doc — accessible directly from any browser on the same network.
