前言
特斯拉提供两种与汽车通信的方式。一种是使用 API 通过互联网，另一种是使用 BLE 连接。BLE 连接有助于锁定和解锁汽车的最重要部分之一，即使汽车和手机或任何其他兼容 BLE 的钥匙扣上没有网络连接。这在两种主要用例中很有帮助，即使在互联网非常不稳定的情况下也是如此。
- 离开汽车时锁好车
- 当你走近汽车时解锁汽车
汽车中低功耗蓝牙 (BLE) 的使用场景不仅限于锁定和解锁车辆。大多数其他命令也可以通过 BLE 直接发送到汽车，而无需完全通过互联网路由命令。但是，需要考虑的一件事是 BLE 在汽车一定距离内的操作范围。
BLE 功能的代码库可在此处找到 --https://github.com/teslamotors/vehicle-command.git
go 环境搭建自行搜索教程
注意：本工具只能运行于 mac 或者 linux， win下不支持。
1. 克隆项目到本地
https://github.com/teslamotors/vehicle-command.git
2. 项目根目录下执行命令
go get ./...
go build ./...
go install ./...
cd cmd
cd tesla-control
go build
3. 生成密钥
生成私钥
openssl ecparam -genkey -name prime256v1 -noout > private.pem
生成公钥
openssl ec -in private.pem -pubout > public.pem
3. 添加汽车公钥
vin码就是车架识别号，类似 7ABCGDEE123ABC555。 在前玻璃地下那里能看到，手机app也能找到。以下用 {youvin} 代替，实际替换为你自己的字符串，{ } 这两个符号也去掉。
./tesla-control -vin {youvin} -ble add-key-request public.pem owner cloud_key
发出命令后，成功的请求将返回以下响应。
向 {youvin} 发送添加密钥请求。通过在中央控制台上轻触 NFC 卡进行确认。
当 NFC 卡在特斯拉汽车的中央控制台上触碰时，汽车显示控制台上会出现一条消息。
特斯拉触摸屏显示一个确认按钮，用于将公钥添加到汽车。
添加钥匙后，它将出现在钥匙列表中，如果您的手机上安装了特斯拉应用程序，也会收到通知。
列出汽车配对的所有钥匙
./tesla-control -vin {youvin} -ble -debug list-keys
4. 解锁/上锁
./tesla-control -ble -vin {youvin} -key-name private.pem -key-file private.pem unlock
./tesla-control -ble -vin {youvin} -key-name private.pem -key-file private.pem lock
6. 后备箱：开，关，开关切换
./tesla-control -ble -vin {youvin} -key-name private.pem -key-file private.pem trunk-open
./tesla-control -ble -vin {youvin} -key-name private.pem -key-file private.pem trunk-close
./tesla-control -ble -vin {youvin} -key-name private.pem -key-file private.pem trunk-move
7. 前备箱开
./tesla-control -ble -vin {youvin} -key-name private.pem -key-file private.pem frunk-open
8. 闪灯
./tesla-control -ble -vin {youvin} -key-name private.pem -key-file private.pem flash-lights
9. 命令帮助
./tesla-control -h
