Interfacing with LoRaWAN RM191 LoRa + BLE Module
●INTRODUCTION
■The RM191 is a wireless communications module that combines a Nordic nRF51822_QFAC (256/16) BLE device and a Semtech SX1272 860 to 1020 MHz low power, long range transceiver. The RM191 is designed to function in the US 902-928 MHz ISM band as opposed to the RM186 which is a very similar device designed for the EU 863-870 MHz ISM band.
■The RM191 can collect data from external sources by interfacing directly with a sensor over a UART, SPI or, l²C serial communication channel or over a wireless BLE connection if a sensor is physically connected to a BLE peripheral device. Data can also be gathered internally using the analog or digital 10 pins. Once the data has been collected and arranged in packets, it can then be transmitted to a remote LoRaWAN Gateway up to 16 kilometers away. From there it can be transmitted to a server or database over a TCP/IP link.
■The purpose of this document is to describe how the RM191 interfaces with the LoRaWAN specification and what is happening inside the module.
