Subject: [Bluez-devel] Inquiry = with RSSI=20 on Broadcom BCM2035 - not supported ?

I have make this question on bluez-users mailing list = some time=20 ago, without answer.

I have tested the D-Link DBT-122 = dongle=20 (BCM2035 chipset) with BlueZ-utils and I find the following features=20 list:

          =      =20 <interlaced pscan> <AFH cap. slave> <AFH cap.=20 master>

Looking the manufactured specification page of = BCM2035=20 chipset it says that it implements the Bluetooth v1.2 specification.=20 Nevertheless I found that it's not true, because this dongle doesn't = support=20 the <Inquiry with RSSI> feature, that belongs to that version = and=20 following of the BT specification.

I have also tested other = usb=20 dongles, for example CSR BlueCore4, successfully with this = feature:

#=20 hciconfig hci0 features

Please, could you confirm me that it's = impossible=20 to make an "Inquiry with RSSI" operation with the BCM2035 chipset from = Broadcom ?
Do you know on existence of an firmware upgrade for this = chipsets that solves this lack ?

I have asked the same = question on=20 D-Link support page without response.
I use Ubuntu Dapper with = Kernel=20 v2.6.15 and BlueZ-utils v2.25.

Thanks for your=20 attention.

Best regards.
