Multi ESP32 signals not fused

[Ying-Kai-Liao]

I prepared 3 ESP32-S3, connected to AP from raspberry pi, and host the aggregator (main server) on the pc. Can receive signals from different node ids but not triggering any kind of signal fusion and fail to detect people count/ pose at all. Barely can say the signal is changing while moving (vitals) but nothing about position / pose is working.

I'm having a similar issue!

Same

I also setup 3 ESP32-S3, and config with "python firmware/esp32-csi-node/provision.py --port COM7 --ssid "YourWiFi" --password "YourPassword" --target-ip 192.168.1.20 --node-id 1" command, but when I use the aggregator to listen the data, it will receive data from 3 different IP but same node_id 1. Do you know why? Or how do you config the node-id?

Thanks!

I already reflash and provision with the "node-id" option today, but it didn't work finally, I don't know how to fix this problem...

I'm also having a similar issue on mac. Nodes have their ids set, I've flashed and re-flashed multiple times, but nothing

Maybe you can use v0.5.1 or v0.5.3 to have a try, I can config with these two version

[panscamera]

no luck with 0.5.3, I'll try with 0.5.1 in a bit but I'm starting to wonder if it's an issue with the rust sensing server

[kuangmh]

modify from write-flash to write_flash in provision.py

I also have the same issure where i flashed 4 nodes with different node id but when i listen to them using nodes endpoints i found only one node id sending data, did you guys found any solution?

It is the promble for a longtime, it cannot read the nodeID in NVS in the older vesion. there maybe two mesthods:

1.using the newer verison(such as 0.55)
or
2. write a program waching the port 5005 in server and trans these CLI message to a new port 5006
2.1, this program distinguished by the IP of esp32 message, and change the nodeID by IP
2.2 run the sensor_server with port 5006

Hey, I've run into similar issues before. The most likely problem is that you're getting RSSI data (just signal strength) instead of CSI data (the detailed channel information you actually need for pose estimation and people counting). Standard WiFi libraries only give you RSSI, which can detect movement/vitals but is useless for positioning or counting people. To get CSI on ESP32-S3, you need to use ESP-IDF's esp_wifi_set_csi_rx_cb() function — the Arduino library won't work. Also, make sure your network actually has traffic flowing (add some constant pings or UDP packets), because CSI only generates data when packets are actively being sent. Before trying multi-node fusion, get a single node working first using something like the RuView firmware — once you see pose estimation working on one device, then worry about combining signals from all three.
