cc1310 空中唤醒(WakeOnRadio)问题

TI工程师们,你好!

我在进行433mHz空中唤醒测试中遇到问题,我发唤醒设备,具体情况如下:

cc1310采用7X7封装

之前用例程中的smartrf_settings配置(见以下文件),可以正常唤醒(但是距离有限)smartrf_settings-OLD.c

将例程中的smartrf_settings配置为433Mhz+5Kbps时(具体配置见一下文件)

7725.smartrf_settings.c

,就无法通信,调试时发现总是PQT检测不通过,导致无法唤醒,调试界面如下: 请TI大神答疑解惑,不胜感激!

Eggsy Pang:

你那个433Mhz+5Kbps的  “5Kbps" 配置是long range mode吧,long range mode是不能用WoR的,编码方式不同

Susan Yang:

It does usually not make sense to implement a Wake-on-Radio scheme with the SimpleLink Long Range Mode.In this mode, it is possible to recover a signal even from below the noise floor (the noise floor is quite high in many regions). On the Gen-FSK PHY, we use RSSI measurement and preamble quality check to quickly determine a signal on the air after wake-up. Both techniques are useless for SimpleLink Long Range mode if the signal level is below the noise floor.
