Editorial narrative

What is RAK3312 WisBlock Core Module for LoRaWAN? RAK3312 WisBlock Core Module for LoRaWAN combines LoRa, WiFi, and Bluetooth communication into one single low power WisBlock Core module. The dual-core Espressif ESP32-S3 MCU powers the device, paired with Semtech SX1262 LoRa transceivers. The LoRaWAN stack is compliant with V1.0.2, with V1.0.4 support in progress. It controls the Semtech SX1262 LoRa transceiver over its SPI interface. The ESP32-S3 firmware is based on the Espressif Arduino BSP for the ESP32. WiFi and Bluetooth functionality is provided by the Arduino BSP. The LoRa drivers and LoRaWAN V1.0.2 stack are available as an Arduino library. RAK3312 comes without a default firmware. We provide code examples in our WisBlock Github repo . Custom firmware for the module, combining the three connectivity options can be developed with Arduino IDE and the Espressif ESP32 BSP or directly using the Espressif ESP-IDF. This module complies with Class A & C of LoRaWAN 1.0.2 specifications. An upgrade to LoRaWAN stack V1.0.4 is in development and will support Class A, B, & C.
