[参考译文] CC1310：从射频内核检索 RSSI

为了验证 RSSI 是否正常、我使用1.5Mbps GHS PHY 和4Mbps PHY 测试了这一点。

我在这两个测试中都使用了 HS API。 我认为可以同时使用1.5 Mbps 的标准 PROP API、但我对两者使用了相同的 API。

以下设置和代码：

设置：

请注意、在 RX 中、我已关闭重复模式、以避免在设置回调中的断点以监控数据包时遇到问题：

在数据包结束时、会附加一个2字节长状态字节和一个4字节长时间戳。

状态字节中的第一个字节是 RSSI。

如您所见、附加的 RSSI 和时间戳等于随该数据包接收的统计信息。
