569 +== 1.8  Example 8: This sketch is supposed to test Dragino RS485-BL (Modbus master), using an Arduino UNO as a Modbus slave. ==
570 +
571 +This sketch uses 4 registers: some of them can be set by Dragino with a command, another is used to store value from a DS18B20 temperature sensor, or a random generated number. All data is 16bit uint, but the sketch shows also how to represent booleans and negative numbers.
572 +
573 +In the next days I will be adding more documentation, but I think it already explains users how to build their own modbus sensor to pair with Dragino RS485-BL.
