- Antenna fifandraisana: Attach a suitable 433MHz antenna to the Ipex connector or solder a wire antenna to the Stamp Hole pad. Ensure the antenna is correctly matched for optimal performance.
- Data Interface: Connect the module's data pins (e.g., UART TX/RX) to your microcontroller or host system. Verify pin assignments from the module's datasheet.
- Fanamboarana: Configure the module's operating parameters (e.g., spreading factor, bandwidth, coding rate, address) using appropriate software or AT commands, as detailed in the Ebyte E22 series documentation.
5. Torolàlana miasa
Once the module is set up, you can begin data transmission:
- fanombohana: Ensure the module is powered on and initialized correctly by your host system.
- Mandefa angona: To send data, transmit your payload through the module's data interface (e.g., UART). The module will then convert this data into Lora packets and transmit them wirelessly.
- Receiving Data: To receive data, the module must be in receive mode. Incoming Lora packets will be demodulated and output through the data interface to your host system.
- Fanamboarana tambajotra: For multi-node networks, ensure all modules are configured with compatible parameters (e.g., same frequency, spreading factor, network ID) to enable successful communication.
For detailed programming and command sets, refer to the official Ebyte E22-400T22S-V2 datasheet and programming guide available on the Ebyte webtoerana.
