我现在有两块调试板，一块是nRF5340DK，一块是nRF52833DK，我现在在nRF52833DK中烧录了direction_finding_connectionless_rx项目，它的地址是nrf\samples\bluetooth\direction_finding_connectionless_rx。在nRF5340中烧录了direction_finding_connectionless_tx项目。两个项目烧录完毕后，direction_finding_connectionless_rx通过串口打印了以下信息：

从调试信息可以看到，它确实监测到了DF Connectionless Beacon设备，但是从未开始进行CTE信息的解析。通过调试，我发现程序已经运行了以下代码：
那么理论上应该运行以下代码：
但实际并未看到打印消息，似乎是k_sem_take未正确返回。我在 k_sem_give(&sem_per_adv); 函数后添加了休眠函数k_msleep(10000);
发现程序正常运行了以下代码：

I currently have two debug boards, one is nRF5340DK and the other is nRF52833DK. I have now programmed the direction_finding_connectionless_rx project into the nRF52833DK. Its address is nrf\samples\bluetooth\direction_finding_connectionless_rx. The direction_finding_connectionless_tx project was programmed into the nRF5340. After both projects were programmed, the direction_finding_connectionless_rx printed the following information through the serial port: Bluetooth initialization... success

From the debugging information, it can be seen that it did indeed detect the DF Connectionless Beacon device, but it never started to parse the CTE information. Through debugging, I found that the program has run the following code:
sync_create_timeout_ms =
adv_interval_to_ms(info->interval) * SYNC_CREATE_TIMEOUT_INTERVAL_NUM;
per_adv_found = true;
per_sid = info->sid;
bt_addr_le_copy(&per_addr, info->addr);
k_sem_give(&sem_per_adv);
Then, theoretically, the following code should be run: err = k_sem_take(&sem_per_adv, K_FOREVER);
if (err) {
printk("failed (err %d)\n", err);
return 0;
}
printk("success. Found periodic advertising.\n");
However, the print message was not actually seen. It seems that k_sem_take did not return correctly. I added a sleep function k_msleep(10000) after the k_sem_give(&sem_per_adv); function and found that the program ran normally with the following code:
err = k_sem_take(&sem_per_adv, K_FOREVER);
if (err) {
printk("failed (err %d)\n", err);
return 0;
}
printk("success. Found periodic advertising.\n");
