BLE with BangleJS and GPS Device

Hi Gordon.

The GPS device does not require any passkey or similar for connect to my phone.

This is the link of the device: http://base.galileosky.com/articles/#!en­-documentation/developing-a-mobile-app-f­or-interacting-with-galileosky-tracking-­devices-via-bluetooth

And this is the script that i used in web ( its work)

    <script>
        const print = (...args) => {
            console.log(...args);
        }
        const UUI_SPS = "0783b03e-8535-b5a0-7140-a304d2495cb7";
        const UUI_SERVER_TX = "0783b03e-8535-b5a0-7140-a304d2495cb8";
        const UUI_SERVER_RX = "0783b03e-8535-b5a0-7140-a304d2495cba";
        const UUI_FLOW_CTRL = "0783b03e-8535-b5a0-7140-a304d2495cb9";
        const DEVICE_NAME = "GS7X 354762118079554";
        const filters = [{ name:  [ DEVICE_NAME ] }];
        const optionalServices = [ UUI_SPS,UUI_SERVER_TX,UUI_SERVER_RX,UUI_­FLOW_CTRL ];

        const button = document.querySelector('button');

        button.addEventListener('click', demo);

        function demo() {
            navigator.bluetooth.requestDevice({ filters, optionalServices })
                .then(device => device.gatt.connect())
                .then(server => server.getPrimaryService(UUI_SPS))
                .then(service => service.getCharacteristic(UUI_SERVER_TX)­)
                .then(characteristic => characteristic.startNotifications())
                .then(characteristic => {
                    characteristic.addEventListener('charact­eristicvaluechanged',
                        handleCharacteristicValueChanged);
                    print('Notifications have been started.');
                })
                .catch(error => { console.error(error); });
        }


        function handleCharacteristicValueChanged(event) {
            const value = event.target.value;
            let a = [];

            for (let i = 0; i < value.byteLength; i++) {
               a.push(value.getUint8(i).toString(16));
            }
            console.log('> ' + a);
    }
    </script>
