[Bluez-users] bc2 vs bc2es firmware

[Pavel Ruzicka <pavouk@pavouk.org>]

Hello,

I see USB dongle with Chip version: BlueCore02 (ES2).
What means ES2?

=46riend tried to flash firmware from manufacturer (rainsun), but it fails.
btdfu tells ""No such device".

This is in log:
=2D-----------------
Dec =A02 23:13:33 a /etc/hotplug/usb.agent: ... no modules for USB product=
=20
a12/ffff/209

=2E..
Dec =A02 23:14:12 a /etc/hotplug/usb.agent: Setup bluetooth for USB product=
=20
a12/1/373
=2D-------------------

It's possible, that in DFU mode will be other ID?
a12/1/373 versus a12/ffff/209

Can be this dongle flashed with GENERIC firmware?
