How do I make the computer visible to the mobile phone?

How do I make the computer visible to the mobile phone?

[Mark Hobley]

I am using Debian (Mixed/Unstable) and I have a Nano Tiny Bluetooth adapter
that uses an Accel Semiconductor microchip. The mobile phone is visible to
the computer, but I cannot see the computer from the mobile phone. How do I
make the computer visible to my mobile phone?

I have enabled both pscan and iscan as follows:

 hciconfig hci0 piscan

The hciconfig tool reveals the following configuration:

hciconfig -a

Does anyone know what the class codes are? Should I change the class code 
in the /etc/bluetooth/main.conf configuration file?

No. I still get that error. However, once in a blue moon, my mobile phone does becomes visibile and the timeout does not occur. I then try to take advantage of this uptime, and I get stung by the invisible computer problem. I am trying to solve both issues.

Ok, this returns 1

I have tried toggling this to both on and off, but the mobile phone still cannot see the computer.

My mobile phone is a Samsung J700, if that matters.

There is some strange stuff going on:

Jun 25 19:48:27 venus udevd[25268]: failed to execute '/usr/local/sbin/bluetoothd' '/usr/local/sbin/bluetoothd --udev': No such file or directory

bluetoothd is in /usr/sbin not /usr/local/sbin. I don't know how to switch that.

Jun 25 19:48:41 venus bluetoothd[916]: input-headset driver probe failed for device 00:1F:CC:C2:E4:86

I don't know what that is. I don't have a bluetooth headset. That is the address of my mobile phone.
