6.1. Basic Operation with Test Kit

If using the Offline Test Evaluation Kit:

Connect the Type-C adapter cable to the kit and a power source (e.g., power bank or computer).
The OLED display will show the current mode (e.g., Home, Setting, Tx Mode, Rx Mode, Version).
Use the 'OK', 'UP', and 'DOWN' buttons to navigate menus and configure parameters. The 'Back' button (Buzzer) can be used to return to previous menus.
The LED indicator provides visual feedback on module status.
For data transmission tests, configure one kit as a transmitter and another as a receiver.

6.2. Data Transfer Example

When performing data transfer tests with two evaluation kits:

Configure the number of times to send data on the transmitting module.
The receiving module can display real-time data such as channel, rate, power, total transmissions (Tx Total), current receptions (Current), lost packets (Lost), and packet loss rate (Lost Pkt %).

Sıcaklık: Operate the module within its specified temperature range (-40°C to +85°C). Avoid extreme temperatures that can affect performance and longevity.
Fiziksel Hasar: Avoid physical stress or impact to the module. Ensure proper mounting to prevent vibrations or accidental disconnections.

8. Sorun Giderme

İletişim yok:
- Check all power connections (VCC, GND) and ensure they are stable and within the specified voltage aralığı.
- Verify SPI connections (MISO, MOSI, SCK, NSS) are correct and securely attached.
- Ensure the EN pin is high for RF operation.
- Check the T/R CTRL pin for correct transmission/reception mode.
- Confirm antenna is properly connected and matched to the module's frequency.
Poor Range/Signal:
- Ensure antennas are correctly installed and have a clear line of sight.
- Check for environmental interference (e.g., other wireless devices, metal obstructions).
- Verify transmit power settings are at the desired level.
- Ensure both modules are operating on the same frequency and with compatible LoRa parameters (e.g., spreading factor, bandwidth).
Modül Yanıt Vermiyor:
- Check the NRST pin. A low level on this pin will reset the chip.
- Verify the power supply is stable and sufficient.
Yazılım Sorunları:
- Double-check your SPI communication code and register configurations.
- Refer to the SX1262 datasheet and EBYTE's documentation for detailed register maps and programming guides.

9. Kullanıcı İpuçları

Anten Seçimi: For maximum range, use a high-gain antenna (e.g., 5dBi) and position it as high as possible with minimal obstructions.
Güç Filtreleme: Always include ceramic filter capacitors on the VCC lines close to the module to ensure clean power and prevent noise from affecting RF performance.
ESD Önlemleri: When handling the module, especially during installation or antenna connection, use an anti-static wrist strap and work on an ESD-safe surface.
Test: When setting up a new communication link, start with short distances and gradually increase the range while monitoring signal quality.
Ürün Yazılımı Geliştirme: Leverage the STM32E103C8T6 on the evaluation kit for custom firmware development to tailor the module's behavior to your specific application needs.
