obdsim: 无效选项 -- 'b'

Question

当我跑步时

user:~$ obdsim -b

我明白了

obdsim: invalid option -- 'b'

我已经这样做了：

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

当我跑步时

user:~$ obdsim -h
Usage: obdsim [params]

       [-d|--customdelay=<ecu delay(ms)>]

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

所以-b 似乎不存在，但它是here。那我想怎么连接蓝牙呢？

Answer 1

这里是原始 OBDSim 开发人员。

这是没有编译蓝牙的典型情况。CMakeLists.txt 的相关部分是：

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)

所以...除非您在构建 OBDSim 时明确禁用蓝牙，否则仅意味着您需要包含您的发行版的 bluetooth-devel 包。

[请注意，安装后，您需要重新运行 cmake，清除缓存。我通常只是 rm -rf build 然后重新开始]
