Hello,

Could someone please describe the "correct" way to handle a failed reconnection attempt?

When gattserverdisconnected fires, I want to try reconnecting for up to 30 seconds, then abort. This seems like a common use-case.

let device, server;
let timeout;

let timeoutPromise = new Promise((_, reject) => {
    timeout = setTimeout(() => reject(new Error('Connection timeout')), 30000);
});

try {
    server = await Promise.race([device.gatt.connect(), timeoutPromise]);
    // successfully reconnected, do other stuff
}
catch(err) {
    // failed to reconnect, how to abort connect()?
    // this often causes `navigator.bluetooth.requestDevice()` to stop responding, perhaps
    // because the browser is still actively trying to connect?
}
finally {
    clearTimeout(timeout);
}

It'd be super helpful if someone could clarify what happens with connect behind the scenes...

• Is there actually a way to abort device.gatt.connect()?
• Is there any browser-level timeout? Or, will a connect() run indefinitely (i.e. the lifetime of the pageload)?
• What does gatt.device.disconnect() do, when a device is disconnected/dropout, or when a connect() is running for that device?

Thanks
