Applications based on Wi-Fi CSI (Channel state information), such as indoor positioning, human detection
I am running the "esp-csi/examples/get-started" example and the problem is that I can receive CSI data as expected. The problem is that if I change the MAC address from {0x1a,...
有以下几个使用问题想进行请教：  1.为何在相同条件（secondary channel : below, HT, 40 MHz, non STBC, v, HT-LFT: 0~63, -64~-1, 384）下运行时，有时收到的CSI数据是256bytes，有时是384bytes，这是由于什么原因导致的呢？还是本身存在的固有缺陷呢？是否存在能固定收发数据的方法呢？另外相较384bytes数据，收到256bytes时，是少了哪一部分数据呢？ 2.关于具体的子载波顺序排列是按照此LLTF：0-63，HT-LFT: 0~63, -64~-1顺序排列的吗？ 3.可否就LLTF和HT-LFT给出一些更加详细的官方说明和解释，解释具体的区别和原理以及二者之间存在的关系吗？ 4.可否对这一示例中的发包频率进行解释。我们发现烧录代码中发送频率为100，但实际处理解析后，一分钟发包量为4700左右，这二者并不对应，可否对此进行解释。  5.关于上一问题中的发包频率，esp32最多可以支持多少呢？具体是否可以给出调整示例 期待并感谢您的回复。
Following the instructions doesn't give any waveform in the gui. Please help as soon as possible, it is very urgent (for a humanitarian cause).
Hi There, When I tried the sub-tasks "csi_recv_router" on different routers. They just responded CSI raw data in the different format layouts as follows (I skipped other information): 1. CSI_DATA,...

Hi, I'm using one esp32s3 and a router to collect CSI data. When I successully build and flash `console_test` project following section 3.2 in `README.md` , I then followed section...
Good day. I am using ESP32 as my receiver and I would like to use D-Link AX3000 router to send CSI data. I have done **3.2 Receive Wi-Fi CSI** to...
I am testing the function of transmitting CSI data to the MQTT server using the example source and ESP32-S3 board. The CSI RX callback specified in the `esp_wifi_set_csi_rx_cb()` method is...
所得到的csv文件中data中的数据格式是单数列为实数，双数列为虚数吗？如果是的也就意味着板载WiFi天线也能得到相位信息是吗？ ESP32-S3能否外接更多的天线来得到更多子载波信息？
