注意事项
除地址参数外，所有指令的参数输入格式必须为十进制
例如当包长0xFF需输入255时：
- 正确示例： AT^SLETX=0,5,255,0,1,2,2,0,0,50
- 错误示例： AT^SLETX=0,5,FF,0,1,2,2,0,0,50
说明： 除地址参数外，其余参数必须是十进制。
部分指令返回值为十六进制
-
发送：
AT^SLETRXEND
-
回复：
OK
status:0x0, num_packet:0x3e8, rssi:-127
说明： 测试RX的收报数为1000包（0x3E8)，RX的当前接收RSSI为-127dBm。
所有参数的间隔符逗号为英文字符
示例如下：
- 正确示例：AT^SLETX=0,5,255,0,1,2,2,0,0,50
-
错误示例：AT^SLETX=0，5，55,0,1,2,2,0,0,50
说明： 不识别中文字符逗号。
串口回复说明
- TRX射频指令测试时，串口回复重点关注“status:0“、“num_packets:3e8“、“rssi:-127“等字样。
- 由于指令执行时序异步，“OK”和其他业务上报打印的先后顺序不是固定的，且涉及BT/BLE/SLE TRX业务的指令，回复“OK”不代表指令正常执行。

图 2 2400MHz频段不同带宽信道对应的射频信道中心频率和射频信道号（下半部分）
说明： 不同带宽的射频测试项需要测的频点不同，例如SLE 4M GFSK指令，测试低频的频点为2405MHz，而不是2402MHz。
