RuuviTag

RuuviTag BT Scanner collects data from all nearby RuuviTag devices.

Supports RuuviTag v3 (RAWv1) and v5 (RAWv2) formats.

Only tested in Linux environments

Usage

copied from example app

Open BT scanner

outputBufferSize := 10
scanner, err := ruuvitag.OpenScanner(outputBufferSize)
if err != nil {
    logger.Fatal(err)
}

Start scanner returns measurement output channel

output := scanner.Start()

Stopping scanner will stop BT scanning and closes output channel

scanner.Stop()

Read incoming RuuviTag measurements from channel

for {
    data, ok := <-output
    if ok == false {
        logger.Println("scanner closed channel")
        break
    }
    logger.Printf("%s[v%d] %.2f / %.2f %%", data.DeviceID(), data.Format(), data.Temperature(), data.Humidity())
}

Examples
