The following example (1) lists available Bluetooth devices when opened as a file in Chrome version 70.
When uploading the same exact example to an Amazon Ligtsail instance I get the following error message:
Uncaught TypeError: Cannot read property 'requestDevice' of undefined
at connect ((index):9)
at HTMLButtonElement.onclick ((index):4)
Can anyone explain to me what the issue might be? Since this is JavaScript, it should be executed in the browser and be unrelated to any server setup?
.
(1) Example code that generates the error on Amazon Lightsail
<html>
<body>
<button onclick="connect();">Click here</button>
<script>
function connect() {
console.log('Getting Bluetooth Device...');
navigator.bluetooth.requestDevice(
{
acceptAllDevices : true
})
.then(device => {
console.log('Got device');
})
.catch(error => {
console.log(error);
});
}
</script>
</body>
</html>
As @kdgregory suggested, the
navigator.bluetoothis HTTPS only:I added a GitHub pages and it works.
