Bluetooth device name not being resolved while scanning

[palande-dev]

I am using the observer to scan for nearby BLE devices and seeing a lot of BLE traffic but their device names are always 'None'. There are Apple TVs and plenty BLE devices around which show up in complete local name when I use other tools
Any suggestions what can I do to resolve names of devices?
Thanks!

I suspect it is because there isn't a scan response being requested.

As the local Name will be added at the end of the scan response data.

This is often referred to as passive and active scanning.
Some more background information at:

The seems to be some support for the different scan types.

python-bleson/bleson/core/hci/constants.py

Lines 7 to 8 in 8566949

	SCAN_TYPE_PASSIVE = 0x00
	SCAN_TYPE_ACTIVE = 0x01

Which platform are you on?

I am using the repo as it is without any changes, and isn't the scan type set to ACTIVE in here by default?

python-bleson/bleson/providers/linux/linux_adapter.py

Line 116 in 8566949

type = SCAN_TYPE_ACTIVE

Which platform are you on?
I am on ubuntu 16.04

It’s late and I’ve just done a whole day followed by a 3 hour drive, so this might be best ignored...

Setting the scan type may just be informative to the BLE stack

Performing the actual scan response parsing and update of the data struct needs to be handheld by Bleson in response to an HCI event, I don’t recall Bleson doing this but I’m too tired to check at the moment, sorry.
