This is one of the main difference with master-slaves protocols, where only the master device can initiate a communication.
Multi-master means that all connected devices will be free to send data when they want. Be reassured, there are libraries that will handle all the low layers for you. You are learning how to use the combo Raspberry Pi + Arduino to build your own projects?Ĭheck out Raspberry Pi and Arduino and learn step by step.īasically it’s an asynchronous multi-master protocol based on the Serial communication, which will allow you to communicate between the 2 boards. UART means “Universal Asynchronous Reception and Transmission”. More specifically, when you use Serial with Arduino and Raspberry Pi, you’re using the UART protocol. The data will be sent sequentially, one bit at a time (1 byte = 8 bits), contrary to parallel communication, where many bits are sent at the same time. Serial communication is simply a way to transfer data.

The results in this test are can send and receive data with the farthest distance at a height 44 meters is 1850 meters with RSSI value -123 dBm and at a height of 1 meters above the ground is 630 meters with RSSI value -115 dBm. On receiver there is motor servo which is used to feed fish. The technology use tool like Arduino Uno as data processor and the data will sent from transmitter to receiver by LoRa 915 MHz, then the data will be displayed on serial monitor in Arduino IDE. So we need the technology that can feed the fish from a long distance. The reason is because owner busy with other activities or because the distance from fishpond is far from home. But fish breeders or the fish owners are often late to feed the fish. Feeding is also needs attention, especially at the right time.
