aioble cannot retrieve device name

[eliclement]

When scanning for BLE devices the name() always returns None.
Using several BLE scanning apps I clearly see the advertised device names...
I am using an ESP32S3 and aioble

import aioble
import uasyncio as asyncio

async def scan():
    print("Scanning for BLE devices...")
    async with aioble.scan(duration_ms=20000) as scanner:
        async for result in scanner:
            name = result.name()
            print(f"Found device: {name}, RSSI: {result.rssi}")

asyncio.run(scan())

I get a list of found devices but no names could be retrieved by aioble.

Scanning for BLE devices...
Found device: None, RSSI: -38
Found device: None, RSSI: -80
Found device: None, RSSI: -52
Found device: None, RSSI: -44
Found device: None, RSSI: -54
Found device: None, RSSI: -37
Found device: None, RSSI: -81
Found device: None, RSSI: -42
Found device: None, RSSI: -63
Found device: None, RSSI: -77
Found device: None, RSSI: -51
Found device: None, RSSI: -71
Found device: None, RSSI: -36

Have you tried running the scan in active mode? Many Bluetooth devices place the device name in the response packet which means the slower active mode is needed.

Try adding active=True argument to the scan() function call.
