xbee

A package for parsing xbee packets sent from a router to a coordinator.

Example data:

[]byte{0x7E, 0x00, 0x16, 0x92, 0x00, 0x13, 0xA2, 0x00, 0x40, 0x4C, 0x0E, 0xBE, 0x61, 0x59, 0x01, 0x01, 0x00, 0x18, 0x03, 0x00, 0x10, 0x02, 0x2F, 0x01, 0xFE, 0x49}

Where

0x7E                                      - delimiter
0x00 0x16                                 - length (from after these two bytes until the checksum)
0x92                                      - frame type
0x00 0x13 0xA2 0x00 0x40 0x4C 0x0E 0xBE   - long address of the sender
0x61 0x59                                 - short address of the sender
0x01                                      - receive options
0x01                                      - number of samples
0x00 0x18                                 - digital channel mask
0x03                                      - analog channel mask
0x00 0x10                                 - digital samples (not present if digital channel mask == 0)
0x02 0x2F                                 - first analog sample
0x01 0xFE                                 - second analog sample
0x49                                      - checksum

To parse this message:

func main() {
	data := []byte{0x92, 0x00, 0x13, 0xA2, 0x00, 0x40, 0x4C, 0x0E, 0xBE, 0x61, 0x59, 0x01, 0x01, 0x00, 0x18, 0x03, 0x00, 0x10, 0x02, 0x2F, 0x01, 0xFE, 0x49}
	x, err := xbee.NewMessage(data)
	if err != nil {
		log.Fatal(err)
	}

	a, err := x.GetAnalog()
	if err != nil {
		log.Fatal(err)
	}

	d, err := x.GetDigital()
	if err != nil {
		log.Fatal(err)
	}

	for k, v := range a {
		fmt.Println(k, v)
	}

	for k, v := range d {
		fmt.Println(k, v)
	}
}

The output will be:

adc0: 655.7184750733138
adc1: 598.2404692082112
dio3: false
dio4: true

The above xml files can be loaded onto the XBees by using XCTU. Once you add the radio module to the user interface you can click on the "Profile" dropdown then click "Load configuration profile".

Wake when a pin goes high

Use the same configuration for the coordinator. The settings below cause the xbee to wake up when pin 9 (Sleep_RQ) is high.
