Hi,
first thank you for making node-ble. Hope it will help me connecting to my devices 👍
I have a question but maybe it is also an issue, I don't know.
I like to start discovery and get the devices discovered so I can decide to which one I like to connect. In my example below I use myAdapter.devices() but is only returns an empty object. Any ideas?
I have bluetoothctl open at the same time and see that discovery starts. I also see the device announcing its UUID after some time but my code shows nothing.
Here my code:
'use strict';
async function main() {
const { createBluetooth } = require('node-ble');
const { bluetooth, destroy } = createBluetooth();
var myAdapter = await bluetooth.defaultAdapter();
console.log(myAdapter.adapter);
if (! await myAdapter.isDiscovering()) {
console.log ("startDiscovery");
myAdapter.startDiscovery();
}
await myAdapter.isDiscovering();
console.log ('isDiscovering');
showDevices();
function showDevices () {
console.log (JSON.stringify(myAdapter.devices(), null,2));
setTimeout (showDevices, 2000);
}
}
main();
I can connect to one of my devices using its UUID (see working code blow). But before being able to do so I first have to find out the UUID which I expected to get with myAdapter.devices().
const device = await adapter.waitDevice('70:BC:10:86:85:C5');
await device.connect();
Support would be appreciated.
Best DrCWO
