matter篇用EFR32BG22做配网的BLE步骤

1、 在原厂提供的ubuntu 虚拟机器下用入下命令配网出现超时错误，可能与没有BLE 功能相关
sudo ./chip-tool pairing ble-thread 1001 hex:0e080000000000010000000300000f35060004001fffe0020811111111222222220708fd67d3ca68dbeac6051000112233445 566778899aabbccddeeff030f4f70656e5468726561642d30653764010212340410b58c67a8a3aaa68557be489b35798ad60c0402 a0f7f8 20202021 384
2、 又没有买推荐的BLE dongle. 手上有silabs 的BLE 板子，有BLE/RCP 固件可以支持HCI 。就开始尝试。

3、 找了块BG22 /BLE开发板开始尝试。应该类似的BG22/MG22/MG21 /MG24/BG24 的开发板，带USB/UART 虚拟串口板都可以。
4、 生成BOOTLOADER 和bt-rcp 固件：


5、 烧录bootloader 和bt-RCP 固件到BG22 开发板。
6、 启用和查看串口：


–USB0 是USBSTICK ttyACM1 是BG22 虚拟串口，ttyACM1 —开始是ttyACM0, 差别串口好增长。不知道如何固定。用之前最好查看。
7、挂载BLE 和用bluetoothctl 测试：
81—sudo btattach -B /dev/ttyACM1 -S 115200

3、看起来用bluetoothctl 测试是正常。
