我试图通过键入来启动 sdk 包
roslaunch dji_sdk sdk.launch
但是每次我收到此错误时：
... logging to /home/dji/.ros/log/b31d5e94-fec0-11e9-9835-74da38ebc18f/roslaunch-manifold2-18825.log

ERRORLOG/1 @ getDroneVersion, L1503: Drone version not obtained! Please do not proceed.
Possible reasons:
Serial port connection:
SDK is not enabled, please check DJI Assistant2 -> SDK -> [v] Enable API Control.
Baudrate is not correct, please double-check from DJI Assistant2 -> SDK -> baudrate.
TX and RX pins are inverted.
Serial port is occupied by another program.
Permission required. Please do 'sudo usermod -a -G dialout $USER' (you do not need to replace $USER with your username). Then logout and login again

这是我激活无人机的步骤：
source devel/setup.bash
catkin_make
rosed dji_sdk sdk.launch
我在哪里编辑波特率/app id/enc key/和序列名。
app_id: 1079440 baud_rate: 921600 serial_name: /dev/ttyUSB0 enc_key: 39d353a8e9ad01b6c659111904bae57ebb138785aa5159699383f28da3f56563
我继续执行以下命令：
roslaunch dji_sdk sdk.launch
它是我得到错误的地方。
我正在使用 USB-TTL 电缆将歧管 2-c 与 M210 RTK V2 连接，在输入任何代码之前，我首先获得了许可：
usermod -a -G dialout $USER
然后注销并登录，然后我输入：
sudo chmod 666 /dev/ttyUSB0
读取并授予串行端口的权限。
TX（绿线）和Rx（白线）和地线（黑线）分别放在那里。
所以现在我该怎么办？
