ANT+ Battery Status

Thanks Kurev,  Yeah I registered the listener too, just without passing in "self".  Output now (from simulator): Listener: deviceState: 1 Ant: [RX] [65, 21, 0, 0, 0, 0, 0, 0] [null][65] Ant: [RX] [66, 0, 0, 0, 0, 0, 0, 0] [null][66] Ant: [RX] [81, 0, 0, 0, 0, 0, 0, 0] [null][81] Ant: [RX] [69, 0, 0, 0, 0, 0, 0, 0] [null][69] Ant: [RX] [67, 0, 0, 0, 0, 0, 0, 0] [null][67] Ant: [RX] [99, 0, 0, 0, 0, 0, 0, 0] [null][99] Ant: [RX] [68, 0, 0, 0, 0, 0, 0, 0] [null][68] Ant: [RX] [113, 0, 0, 0, 0, 0, 0, 0] [null][113] Ant: [RX] [75, 0, 0, 0, 0, 0, 0, 0] [null][75] Ant: [RX] [5, 1, 255, 255, 205, 242, 8, 254] [130641][5] Ant: [RX] [5, 1, 255, 255, 205, 242, 8, 254] [130641][5] Ant: [RX] [1, 5, 0, 0, 0, 0, 0, 0] [null][1] Listener: deviceState: 3 Ant: [RX] [2, 1, 129, 0, 205, 242, 8, 254] [130641][2] Ant: [RX] [1, 5, 0, 0, 0, 0, 0, 0] [null][1] Ant: [RX] [3, 187, 23, 9, 205, 242, 8, 254] [130641][3] Ant: [RX] [1, 5, 0, 0, 0, 0, 0, 0] [null][1] Ant: [RX] [4, 255, 235, 50, 205, 242, 8, 254] [130641][4] Ant: Battery Status 0x04: state: 3, voltage: 2.917969 Ant: [RX] [1, 5, 0, 0, 0, 0, 0, 0] [null][1] Ant: [RX] [5, 1, 255, 255, 205, 242, 8, 254] [130641][5] Ant: [RX] [5, 1, 255, 255, 205, 242, 8, 254] [130641][5] Ant: [RX] [4, 255, 233, 50, 205, 242, 8, 254] [130641][4] Ant: Battery Status 0x04: state: 3, voltage: 2.910156 Ant: [RX] [4, 255, 233, 50, 205, 242, 8, 254] [130641][4] Ant: Battery Status 0x04: state: 3, voltage: 2.910156 Ant: [RX] [4, 255, 233, 50, 205, 242, 8, 254] [130641][4] Ant: Battery Status 0x04: state: 3, voltage: 2.910156 Ant: [RX] [4, 255, 233, 50, 205, 242, 8, 254] [130641][4] Ant: Battery Status 0x04: state: 3, voltage: 2.910156 Ant: [RX] [5, 1, 255, 255, 205, 242, 8, 254] [130641][5] Ant: [RX] [5, 1, 255, 255, 205, 242, 8, 254] [130641][5] Ant: [RX] [2, 1, 129, 0, 205, 242, 8, 254] [130641][2] Ant: [RX] [5, 1, 255, 255, 205, 242, 8, 254] [130641][5]

And you did register the listener too, doing something like this:    var mySpeedListener = new MyBikeSpeedListener(self);    var mySpeedDevice = new AntPlus.BikeSpeed(mySpeedListener); Here is slightly improved version, handling both common page and page 4. It also prints out all pages it receives, so you should definitely see something coming out. It is ok to use on simulator, but on real device the 1k + 1k file buffers will overflow quickly. Just disable the first print if it's too much:

    function onMessage(msg) {
        var payload = msg.getPayload();
        var page = payload[0] & 0x7F;
        Sys.println("Ant: [RX] " + payload + " [" + msg.deviceNumber + "][" + page + "]");
        
        if (page == 0x52) {
            var state = (payload[7] >> 4) & 0x7;

            var voltage = (payload[7] & 0xF);
            if (voltage != 0xF) {
                voltage = voltage + (payload[6] / 256.0);
            } else {
                voltage = 0.00;
            }

            Sys.println("Ant: Battery Status 0x52: state: " + state + ", voltage: " + voltage);
        }
        if (page == 0x04) {
            var state = (payload[3] >> 4) & 0x7;

            var voltage = (payload[3] & 0xF);
            if (voltage != 0xF) {
                voltage = voltage + (payload[2] / 256.0);
            } else {
                voltage = 0.00;
            }

            Sys.println("Ant: Battery Status 0x04: state: " + state + ", voltage: " + voltage);
        }
    }

This will give me on simulator with Garmin Speed 2 following print on page 4 (and battery state is available ok):

Ant: [RX] [4, 255, 2, 51, 210, 22, 3, 0] [287300][4]
Ant: Battery Status 0x04: state: 3, voltage: 3.007812

Speed sensor is not broadcasting page 82, I'll try later if I can get it with sendPageRequest().

Sorry (haven't used that before).  Yep, so it's paired now - went from grey to yellow to green and so far, one message output (still running): Listener: deviceState: 3 Code was this:

class MyBikeSpeedListener extends AntPlus.BikeSpeedListener {

    function initialize() {
        BikeSpeedListener.initialize();
		Sys.println("Starting BikeSpeed.Listener");
    }

    function onDeviceStateUpdate(data){
        Sys.println("Listener: deviceState: "+ data.state);
    }

    function onBatteryStatusUpdate(data){
        Sys.println("Listener: batteryStatus: " + data.batteryStatus);
    }

	function onMessage(msg) {
		var payload = msg.getPayload();
		if ((payload[0] & 0x7F) == 0x52) {
			Sys.println("Ant: [RX] " + payload + " [" + msg.deviceNumber + "], PAGE_BATTERY_STATUS");

			var state = (payload[7] >> 4) & 0x7;

			var voltage = (payload[7] & 0xF);
			if (voltage != 0xF) {
				voltage = voltage + (payload[6] / 256.0);
			} else {
				voltage = 0.00;
			}

			Sys.println("Ant: Battery Status: state: " + state + ", voltage: " + voltage);
		}
	}
}

Grey means not paired... Try right-clicking on the item and hit pair. Should turn green.

Hey Kurev, just reporting back.  I added a bikeSpeed Listener class (including your onMessage function and appropriate initialisation at the start) into my app to test.  I can see my Speed Sensor in the "ANT+ Sensors" view under the simulator, though it does show a status with a grey circle (not sure what that means); I can see my sensor on my Fenix5+ and it reports Battery:  OK.  Running my app (and it's been running for 20 mins), I'm not seeing any messages at all coming out of the listener (except for one I added into initialize()).  Is that what you expected?  My Garmin sensor is definitely ANT+ (It's imprinted on the back).
