Signal Hunt: An ESP-NOW Workshop & Treasure Hunt

Hello everyone! We’re planning on organizing a two-phase event that explores device-to-device communication using ESP-NOW protocol :

Workshop: Participants learn to build and program ESP32-based receivers with a web interface that directly exchange signal data using ESP-NOW for RSSI-based distance approximation.

Signal Hunt Competition: Equipped with these receivers, participants will track hidden ESP32 transmitters scattered around the campus, each with distinct point values.

Current hardware setup:
Reciever(one per team):
Esp32 ~ 360rs
9v battery = 20rs
9v battery clip= 5rs
buck converter (MP1584 or LM2596) ~ 45rs
Perfboard + male to female berg strip ~30rs
Total per reciever ~ 460rs
Transmitters :6
Components same as recievers = 460*6~2760rs

(using non-rechargeable batteries to reduce cost,
will using a 7805 voltage regulator IC be a viable way to reduce cost further?)

We’d love your suggestions on ways to simplify hardware, reducing the cost, secure partnerships and funding, or enhance the interactive elements. Thank you, looking forward to any ideas that can help make the event engaging and successful!

I am trying to set up a janus webrtc to stream an RTSP to an HTML page.
I have followed the getting-started steps by Janus-gateway official github repo.

Since I am new to web development. I do not understand how to host the Webrtc server. can anyone guide me to set up an HTML page that can display a video stream from an RTSP server using janus webrtc?

@zainmuhammed Can try capturing the GPS when the device is starting the loop instead after joining the LoRaWAN and see?

You can put the GPS value on top of the loop or setup function.

Also, what kind of gateway are you using? Is it configured okay, OTA is done?

@salmanfaris Today I tried after connecting a 18650 cell,

Data getting in console after integration of both lora and gps.

here you can see that GPS value is 0,0. also in my previous post you can see that GPS value is not reading.
Also the status LED is active after it is connected to the satellite.
