Default Firmware Function Description

There are two default firmware options available:

• AiPi-LoRaBoard_v0.0.5.bin
• AiPi_uno_loraBoard.bin

AiPi-LoRaBoard_v0.0.5.bin is the firmware for the Rd-08, which can be set to two modes: host and client. When operating in host mode, it functions as a gateway, receiving data sent from clients. In client mode, it can actively send data to the host.

AiPi_uno_loraBoard.bin is the firmware for the AiPi-UNO-ET485, primarily configuring the Rd-08 as a host and displaying client data on the 1.9-inch screen. It also allows for the setting of the Rd-08's operating frequency range and some LoRa parameters, such as the spreading factor. Thus, this firmware is only useful when the Rd-08 runs the AiPi-LoRaBoard_v0.0.5.bin firmware.

Instructions for Using AiPi-LoRaBoard:

After installing the AiPi-LoRaBoard onto the AiPi-UNO-ET485 and powering it up, the LoRa on the AiPi-LoRaBoard operates under the following parameters:

Frequency (Freq): 470000000

Spreading Factor (SF): 7

Bandwidth (BW): 0

CRC: 1

The default interface displays data monitoring, initially showing data from the AiPi-LRW-TH1. 

You can slide left to enter the configuration page, where you can set the main LoRa parameters.

Instructions for Using LoRa Nodes: 

To have the AiPi-LoRaBoard receive and display data, you need to flash AiPi-LoRaBoard_v0.0.5.bin, then configure it to client mode. After a successful flash, use a serial assistant to send the AT command (baud rate 115200): AT+MODE=1. Once configured, the AiPi-LRW-TH1 will automatically send temperature and humidity data to the host.
