 ====== Pair Bluetooth Controllers - manual setup ======
-You need to establish a [[access_the_batocera_via_ssh|SSH connection]] or a terminal windows with keyboard to accomblish this further. You can connect your bluetooth controller manually by doing some commands step by step.
+First ensure that Bluetooth is enabled on your device. First, the line ''controllers.bluetooth.enabled=1'' should be present in your ''system/batocera.conf'' file and not commented out ([[:batocera_conf_syntax|how to access the batocera.conf file]]). If it is missing, add it in. Note that doing this won't suddenly make a non-functional Bluetooth dongle start working, only the ones that are already compatible with the Linux kernel and the drivers included in Batocera.
-Get started by typing ''bluetoothctl'' and hitting ''[Enter]''.
+Establish an [[:access_the_batocera_via_ssh|SSH connection]] (or open up Xterm) to start the manual connection process. Get started by typing ''bluetoothctl'' and hitting ''[Enter]''.
 Now you are in the Bluetooth control unit. Type following commands and confirm every single one with ''[Enter]''
-    agent on
+<code>
-    default-agent
+agent on
-    power on
+default-agent
-    scan on
+power on
+scan on
+</code>
 Now set the controller in pairing mode! This strongly depends from your [[:supported_controllers|controller type]].

+===== Batocera is automatically pairing a device I don't want it to! =====
+Some devices out there break Bluetooth protocol and are always in "pairing" mode, common with modern "smart" TVs. Since Batocera will automatically connect to any device in pair mode, this could cause unintended connections.
+To work around this, it is possible to pair to only strictly pads. Put your controller into its pairing mode and then run the following:
+<code>
+batocera-bluetooth trust-pad
+</code>
+Batocera will explicitly only search for and connect to Bluetooth controllers. This may take a while as it methodically goes through, parses and accepts/rejects devices in the background. Once the pad is found, Batocera will attempt to pair to it:
+<code>
+[root@RPI3-BATOCERA /userdata/system]# batocera-bluetooth trust-pad
+Pairing 8BitDo M30 gamepad...
+Trusting 8BitDo M30 gamepad...
+[root@RPI3-BATOCERA /userdata/system]#
+</code>
+The Bluetooth controller can now be used with Batocera.
+Conversely, the same can be done to connect strictly to audio devices:
+<code>
+batocera-bluetooth trust-audio
+</code>
+--> Blacklisting a device in Batocera v33 #
+<WRAP center round important>
+The functionality of this has been supplanted by ''trust-pad'' method described above. These instructions are retained here specifically for Batocera **v33** and no other version.
+</WRAP>
+There might be some device that is perpetually in pairing mode that you don't want your Batocera machine to connect to (such as your neighbor's "smart" TV). You can block such devices by utilizing the blacklist.
+In order to do this via SSH, run the following command:
+<code>
+batocera-bluetooth blacklist <device address> <device name>
+</code>
+For example:
+FIXME
+To show a list of all the currently blacklisted devices:
+<code>
+batocera-bluetooth list_blacklistable
+</code>
+To remove a device from the blacklist:
+<code>
+batocera-bluetooth unblacklist <device address>
+</code>
