RAKwireless WisDuo LoRaWAN Module RAK11720 w/ IPEX for EU868/RU864/IN865

Configure the RAK11720 for EU868 by setting the correct regional parameters in your firmware, typically via AT commands or LoRaWAN stack configuration. You must select the EU868 frequency plan, which defines the specific channels and data rates. Ensure your LoRaWAN network server (like The Things Network or ChirpStack) is also set to the same region. The module's IPEX connector should be paired with a certified 868MHz antenna for optimal performance and regulatory compliance.

The RAK11720 features ultra-low sleep currents (typically in the microamp range) and configurable active modes. Maximize battery life by utilizing the deepest available sleep mode between transmissions and minimizing the radio-on time. Program your application to send data at the slowest acceptable duty cycle and use adaptive data rate (ADR) to reduce transmit power when possible. Power management is handled through the MCU's sleep functions and the SX1262's built-in low-power states.

Yes, the RAK11720 supports direct point-to-point (P2P) LoRa communication in addition to LoRaWAN mode. For P2P, you configure both transmitter and receiver modules with identical parameters: frequency, spreading factor, bandwidth, and coding rate. This mode is useful for creating simple private links, testing range, or applications that don't require a full network server. You will need to implement the simple peer-to-peer protocol in your firmware on both devices.

Develop for the RAK11720 using the RAKwireless WisToolBox for device management and firmware updates. For embedded programming, use the ARM GCC toolchain with platforms like PlatformIO or Keil MDK. RAKwireless provides example code and libraries for LoRaWAN stacks (like Semtech's LoRaMac-node) and basic HAL drivers. You can also use AT command sets via a serial connection for rapid prototyping and testing without deep firmware development.
