4. الإعداد

4.1 الأسلاك

Connect the RP1 V2 receiver to your flight controller or other compatible device using the provided CRSF wire or by soldering directly to the pads. Ensure correct polarity and data line connections.

• 5V: Connect to a 5V power source from your flight controller.
• أرض الواقع: Connect to the ground (negative) terminal of your power source.
• TX (إرسال): Connect to the RX (Receive) pad on your flight controller's UART.
• RX (استقبال): Connect to the TX (Transmit) pad on your flight controller's UART.

4.2 إجراء ملزم

To establish a connection between your RP1 V2 receiver and your ExpressLRS transmitter module, follow these steps:

1. Ensure your ExpressLRS transmitter module is powered on and set to binding mode.
2. Power on your RP1 V2 receiver.
3. Immediately power off the receiver.
4. Repeat steps 2 and 3 two more times. After the third power cycle, the receiver's LED should begin a rapid double flash, indicating it is in binding mode.
5. Once the receiver is in binding mode, activate the binding function on your ExpressLRS transmitter.
6. A successful bind is indicated by a solid LED on the receiver. If the LED remains flashing, repeat the binding process.

5. تعليمات التشغيل

5.1 Firmware Updates via WiFi

The RP1 V2 receiver features built-in WiFi, allowing for convenient firmware updates and configuration without needing a physical connection to a computer.

1. Power on the receiver. If it is not connected to a transmitter, it will automatically enter WiFi hotspot mode after a short period.
2. On your computer or mobile phone, search for available WiFi networks and connect to the network named "ExpressLRS RX" (or similar, depending on firmware version). The default password is "expresslrs".
3. افتح web المتصفح وانتقل إلى 10.0.0.1. This will open the ExpressLRS WebUI.
4. من WebUI, you can update the receiver's firmware by uploading the appropriate .bin file or configure various settings.
5. After updating or configuring, save your changes and reboot the receiver.

5.2 التشغيل العادي

Once bound and configured, the RP1 V2 receiver will automatically connect to your transmitter upon power-up. The solid LED on the receiver indicates a successful connection. The low-latency and high-refresh-rate capabilities of ExpressLRS ensure precise and responsive control for your RC model.

6. الصيانة

To ensure the longevity and optimal performance of your RadioMaster RP1 V2 receiver, consider the following maintenance guidelines:

• حافظ على نظافة: Regularly inspect the receiver for dust, dirt, or debris. Use a soft, dry brush or compressed air to gently clean the PCB and connectors.
• الحماية من العناصر: Avoid exposing the receiver to moisture, extreme temperatures, or direct sunlight. Consider using conformal coating or heat shrink for additional protection in harsh environments.
• فحص الاتصالات: Periodically check all soldered connections and the UFL antenna connector for any signs of damage or looseness. Ensure the antenna is securely attached and positioned correctly.
• تحديثات البرامج الثابتة: Keep the receiver's firmware updated to the latest stable version to benefit from performance improvements and bug fixes.

7. استكشاف الأخطاء وإصلاحها

If you encounter issues with your RP1 V2 receiver, refer to the following common troubleshooting steps:

• جهاز الاستقبال غير مرتبط:
  • Ensure your transmitter module is also running the same ExpressLRS firmware version as the receiver.
  • Verify the binding procedure (three power cycles) is performed correctly.
  • Check that the transmitter is in binding mode and transmitting.
  • Confirm the correct firmware target (RadioMaster RP1/2 2400 RX) was flashed to the receiver.
• No Telemetry/Control:
  • Check all wiring connections (5V, GND, TX, RX) for correct polarity and secure soldering.
  • Verify the UART settings on your flight controller are configured for CRSF protocol.
  • Ensure the antenna is properly connected to the UFL port.
• Short Range/Signal Loss:
  • Inspect the antenna for any damage or kinks.
  • Ensure the antenna is mounted away from carbon fiber, batteries, or other conductive materials that can block the signal.
  • Check the power output settings on your transmitter module.
  • Consider environmental factors that might interfere with 2.4GHz signals.
• WiFi Hotspot Not Appearing:
  • Ensure the receiver is powered on and not currently connected to a transmitter. It typically enters WiFi mode after a few seconds if no transmitter connection is found.
  • Try power cycling the receiver again.
