Silicon Labs EFR32BG21 蓝牙SoC RCP模式测试-扫描设备
SILICON LABS EFR32BG系列蓝牙SoC芯片支持RCP模式（Radio Co-Processor），RCP模式简单说就是BG21运行蓝牙控制器（即仅链路层），蓝牙协议栈在主机上运行，主机通过UART连接BG21，使用标准HCI（主机控制器接口）对其访问控制实现蓝牙BLE功能。
本文介绍测试EFR32BG21 蓝牙RCP模式工作在主模式，用于扫描蓝牙从设备，建立蓝牙连接和收发数据。首先需要准备一台电脑并且已经安装好了linux系统。也可以是windows系统下安装的linux虚拟机。并且已经安装好了蓝牙BlueZ协议栈。
1、首先可以通过命令查询当前bluez的版本，检查linux环境下BlueZ是否正确安装：
bluetoothctl --version
例如：
Linux@RCP:~/bluez_5_60$ bluetoothctl --version
bluetoothctl: 5.60
可以看到已经正确的返回了BlueZ版本号，说明BlueZ已经安装正确了。
烧录bootloader和蓝牙RCP固件到EFR32BG21以后，可以使用windows环境下的串口工具测试串口和固件是否正常运行。串口工具发送（hex值）：01 03 0C 00（这条是复位命令），BG21会回复：04 0E 04 01 03 0C 00。如果正确的收到返回数据。说明RCP和串口都正常运行了。示例：
发送：01 03 0C 00
接收：04 0E 04 01 03 0C 00
或者使用这条设置扫描参数的命令来测试：
发送：01 0B 20 07 01 30 00 30 00 00 00
接收：04 0E 04 01 0B 20 00
2、然后需要准备一个能正常工作的BLE蓝牙从设备。本文测试使用的是采用EFR32BG系列的蓝牙评估板，烧录Bluetooth - SoC Thermometer固件。相关的设备信息是：[NEW] Device 60:A4:23:C9:6D:11 Thermometer Example，其中Temperature Measurement特征字具备notify属性。会周期上报测量的温度值。Characteristic发现的示例：

3、本文测试用到的命令：
Linux@Linux:~$ sudo hciattach /dev/ttyACM0 any 115200 noflow
（命令说明：如果RCP带串口流控，可以把noflow去掉）
Linux@Linux:~$ hciconfig -a
Linux@Linux:~$ bluetoothctl
[bluetooth]# scan on
[bluetooth]# scan off
[bluetooth]# connect 60:A4:23:C9:6D:11 （找到需要连接的蓝牙设备地址填入到此）
[Thermometer Example]# info
[Thermometer Example]# pair
[Thermometer Example]# menu gatt
[Thermometer Example]# list-attributes
[Thermometer Example]# select-attribute /org/bluez/hci0/dev_60_A4_23_C9_6D_11/service0019/char001a
（选择需要操作的Characteristic）
[Thermometer Example:/service0019/char001a]# notify on
[Thermometer Example:/service0019/char001a]# notify off
[Thermometer Example:/service0019/char001a]# select-attribute /org/bluez/hci0/dev_60_A4_23_C9_6D_11/service0019/char001d
[Thermometer Example:/service0019/char001d]# read
[Thermometer Example:/service0019/char001d]# quit
4、以下是完整的测试log，对应前面介绍的每一条命令下发之后，RCP端返回给linux的数据和信息等：
