obdsim: invalid option -- 'b'

When I run

user:~$ obdsim -b

I get

obdsim: invalid option -- 'b'

I've already done this:

sudo rfcomm bind 0 14:30:C6:50:12:16 1
sudo sdptool add SP

When I run

user:~$ obdsim -h

The generators built into this sim:
 "Random"
 "Cycle" (default)
 "Logger"
 "dlopen"
 "Socket"
 "gui_fltk"
 "Error"

So it seems that -b is not there however it's here. So how am I suppose to connect to bluetooth?

Solution

Original OBDSim developer here.

That's typical of not having bluetooth compiled in. The pertinent part of CMakeLists.txt is thus:

SET(OBD_SIM_DISABLE_BLUEZ false CACHE BOOL "Disable bluetooth support in obdsim")
IF(NOT OBD_SIM_DISABLE_BLUEZ)
    CHECK_SYMBOL_EXISTS(BTPROTO_RFCOMM
        bluetooth/bluetooth.h
            HAVE_BLUETOOTH)
    IF(HAVE_BLUETOOTH)
        MESSAGE(STATUS "Enabling bluetooth obdsim port")
        ADD_DEFINITIONS(-DHAVE_BLUETOOTH)
    ENDIF(HAVE_BLUETOOTH)
ENDIF(NOT OBD_SIM_DISABLE_BLUEZ)

So... unless you explicitly disabled bluetooth when you built OBDSim, it simply means you need to include your distribution's bluetooth-devel package.

[Note that after installing, you will need to rerun cmake, having obliterated the cache. I usually just rm -rf build and start again]
