- Attach Antennas: Connect the IPEX LoRa PCB Antenna and the IPEX BLE PCB Antenna to their respective connectors on the RAK4631 module.Important: Ensure antennas are connected BEFORE powering on the device. Operating without antennas can damage the transceiver.
- Secure with Screws: Use the provided assembly screws to secure the modules if necessary, though they are often held by friction.
4.2. Initial Power and Firmware
- Connect USB Power: Connect the USB Type-C end of the provided cable to the RAK19003 Base Board and the Type-A end to a computer or USB power adapter.
- Firmware Status: The kit comes pre-flashed with a working version of Meshtastic firmware. However, it may not be the absolute latest version upon delivery due to shipping times.
- Firmware Updates: Firmware updates are freely available from the official Meshtastic website. To update, connect the device to your computer, visit the Meshtastic web flasher, select your device and firmware version, and follow the on-screen instructions.
4.3. Battery Connection (Optional)
If using a battery (not included), connect it to the designated battery connector on the RAK19003 Base Board. The board includes an on-board solar charge controller for 3.7V LiPo batteries if a solar panel is connected.
Caution: Always check battery polarization (positive to positive, negative to negative) before connecting to avoid damaging the board. Refer to the board's markings.

5. Operating Instructions
5.1. Meshtastic App Integration
The RAKwireless WisBlock Mini Meshtastic Starter Kit is designed for seamless integration with the Meshtastic application, available for both iPhone and Android devices. A screen is not required on the device itself as all operations can be managed through the app.
- Download the App: Search for "Meshtastic" in your device's app store and install it.
- Connect to Device: Open the Meshtastic app. It will scan for nearby Meshtastic devices via Bluetooth. Select your RAKwireless device from the list to establish a connection.
- Configure Settings: Within the app, you can configure various settings such as channel, device name, and other network parameters.
5.2. Mesh Network Functionality
Meshtastic creates an off-grid mesh network using LoRa radio technology. Key operational aspects include:
- Message Transmission: Send messages directly from the Meshtastic app. Your device will transmit these messages over the LoRa network.
- Node Forwarding: Other Meshtastic devices (nodes) within range will receive and automatically forward messages, extending the communication range across the network. This allows communication over kilometers/miles.
- Internet Integration: If an internet-connected relay node is part of your mesh, messages can be relayed to online platforms, bridging the off-grid network with the internet.
6. Maintenance
Regular maintenance primarily involves keeping the device's firmware updated to ensure optimal performance, access to new features, and security enhancements.
- Firmware Updates: Periodically check the official Meshtastic website for the latest firmware versions. Follow the instructions provided on their site for updating your device.
- Physical Inspection: Ensure all connections, especially antenna connections, are secure. Keep the device clean and free from dust and moisture.
7. Troubleshooting
If you encounter issues with your RAKwireless WisBlock Mini Meshtastic Starter Kit, consider the following:
- Device Not Powering On:
- Ensure the USB cable is securely connected to both the device and a power source.
- If using a battery, verify it is charged and correctly connected with proper polarization.
- Cannot Connect to Meshtastic App:
- Ensure Bluetooth is enabled on your smartphone.
- Verify the device is powered on and within Bluetooth range.
- Restart both the device and the Meshtastic app.
- Check if the firmware is up to date.
- Poor Range or Communication Issues:
- Confirm that both LoRa and BLE antennas are securely attached.
- Ensure there are no major obstructions between devices.
- Consider the environment; dense urban areas or heavy foliage can reduce range.
