RisingHF RHF0M062 Datasheet 4.2 Interface of Module Except that several essential GPIOs and one group of SPI would be used for internal transceiver control, all others GPIOs and interface of the MCU would be connected to external pins of the module, which includes UART, I2C, ADC and so on. 4.3 Reference design with RHF0M062 Module RHF0M062 is integrated with LoRaWAN protocol and AT command. LoRaWAN node design with RHF0M062 is very simple. Just connect the UART and NRST to their host MCU with AT command. In addition, the module's Pin12 grounding will force the module into the Boot upgrade mode. 5 Application in LoRaWAN 5.1 LoRaWAN LoRaWAN network is typically a star topology in which gateways relay messages between end-devices and a central network server. Gateways are connected to the network server via standard IP connections while end devices use single-hop LoRa™ or FSK communication to one or many gateways. All communication is generally bi-directional, although uplink communication from an end device to the network server is expected to be the predominant traffic. Communication between end-devices and gateways is spread out on different frequency channels and data rates. The selection of the data rate is a trade-off between communication range and message duration, communications with different data rates do not interfere with each other. LoRa data rates range from 0.3 kbps to 50 kbps, with different Bandwidth and Spreading Factor. To maximize both battery life of the end-devices and overall network capacity, the LoRa network infrastructure can manage the data rate and RF output for each end-device individually by means of an adaptive data rate (ADR) scheme. End-devices may transmit on any channel available at any time, using any available data rate, as long as the following rules are respected: 1) The end-device changes channel in a pseudo-random sequence for each transmission. This results in frequency diversity and makes the system more robust to interference. 2) The end-device respects the maximum transmit duty cycle relative to the sub-band used and local regulations.
