Hi,
I am attempting to test SPP profiles - both inbound and outbound
connections using a Laird WB50N module. This is an embedded device
running Linux and the firmware includes BlueZ version 5.43
I am attempting to configure SPP via these commands:
###
# /usr/bin/nohup /usr/libexec/bluetooth/bluetoothd &
# nohup: appending output to nohup.out
# bluetoothctl
[NEW] Controller D0:12:6B:0B:E7:E8 BlueZ 5.43 [default]
[NEW] Device B0:05:94:F3:4F:F9 ubuntu-0
[NEW] Device 00:16:A4:0B:F3:84 LAIRD BT900
[bluetooth]# discoverable on
Changing discoverable on succeeded
[CHG] Controller D0:12:6B:0B:E7:E8 Discoverable: yes
[bluetooth]# pairable on
Changing pairable on succeeded
[bluetooth]# agent
Missing on/off/capability argument
[bluetooth]# agent on
Agent registered
[bluetooth]# default-agent
Default agent request successful
[bluetooth]# quit
Agent unregistered
[DEL] Controller D0:12:6B:0B:E7:E8 BlueZ 5.43 [default]
(note sure if the above was required or not)

At this point, if I query the device from a nearby linux box - I see this:

No sign of any SPP support.
I'm obviously missing something, but many google searches later I have
nothing to show for it. (I also searched this mailing list archives -
very little discussion on SPP)
If this is documented someplace, I'd appreciate a pointer to it.
thanks!
Jim
