Hi all,

You guys from the Gentoo community are my last hope on this. I have tried with Debian-based distros, Gentoo... but couldn't find an answer.
I am trying to connect a BT device to a Raspberry Pi. Thing is, this is an embedded-like enviroment I have to setup, so no BT services are allowed: I just need to connect it, no need to store settings, restore on boot, etc...no, just establish a connection.

So far I have got to setup the device and add it to the HCI:

Code:
sudo modprobe hci_uart
sudo modprobe btbcm
sudo hciattach /dev/ttyAMA0 bcm43xx 921600 noflow -


I can see it's working without problems with:
Code:
sudo hciconfig -a


I can easily bring up the device like this:
Code:
sudo hciconfig hci0 up

I can even scan devices with sudo hcitool scan, and I can see the target devices in range. Great so far!

The problem comes when I try to connect the Pi3b+ to them.
There used to be
Code:
hidd --connect <address>
, but the hidd command has been deprecated in favor of some mumbo-jumbo using DBUS and systemd services. I guess a service is needed to manage connections, etc, but all I need here is to manually stablish an one-time BT connection manually. Simple.
So, what should I use in place of
Code:
hidd --connect <address>
now?

I have tried
Code:
sudo hcitool cc <address>
, but it doesn't stablish any connections (connections can be verified with hcitool con).

VanFanel,

Its been a while but I think you get the old tools if you emerge net-wireless/bluez with USE=deprecated.

The old was has not been removed, just hidden.

Moved from Other Things Gentoo to Gentoo on ARM.

Its likely to be more use here.
