RAK3172 - WisDuo LoRaWAN Module

The RAK3172 LoRa Module includes a STM32WLE5CC chip, which supports eight (8) spreading factors (SF5 ~ SF12) and signal bandwidth that can be adjusted between 7.8 kHz to 500 kHz. It has Ultra-Low Power Consumption of 1.69 μA in sleep mode, but during the Transmit Mode, it can reach the maximum output power of 22 dBm. As a receiver, it can achieve a sensitivity of -148 dBm.

RAK3172 Overlooked but Useful LoRaWAN® AT Commands

The RAK3172 WisDuo module with the default RAK firmware is usually used as a LoRaWAN modem together with the host MCU in most IoT applications. You can have a successful end-device when the host MCU sends even just the basic EUIs/keys commands and joining/sending commands.
