    Thank you for your response! @salmanfaris 🙂

    It makes sense that filtering out the specific data points that are needed and sending them to the cloud would be the way to go.

    If it's not too much trouble, could you please provide me with an example of how to filter out and send only the necessary inferencing data to the cloud?

    Thank you again for your help!

    Best,

      @dipu_varghese Sure, I'll try to make an example in one coming day and share.

              Hi @dipu_varghese ,

              Here is the sample input from the binary edge impulse inference,

              Predictions (DSP: 16 ms., Classification: 1 ms., Anomaly: 2 ms.):
              idle: 0.91016
              snake: 0.08203
              updown: 0.00391
              wave: 0.00391
              anomaly score: -0.067”
              

              And from here for example we can try to get the updown values only by attaching the device to another controller and read the Serial string directly.

              void setup() {
                // Start serial communication at 9600 baud
                Serial.begin(9600);
              }
              
              void loop() {
                // Wait until there is data available on the serial port
                while (!Serial.available()) {
                  // Do nothing
                }
              
                // Read the input string from the serial port
                String inputString = Serial.readStringUntil('\n');
              
                // Find the position of the "updown" value in the input string
                int updownPos = inputString.indexOf("updown:");
              
                // If the "updown" value was found in the input string
                if (updownPos >= 0) {
                  // Extract the "updown" value from the input string
                  String updownString = inputString.substring(updownPos + 8, inputString.indexOf('\n', updownPos));
              
              // Convert the "updown" value to a float
                  float updownValue = updownString.toFloat();
              
               // Output the "updown" value
                  Serial.println(updownValue);
                }
              }
              

              The sketch should then output the "updown" value, which is 0.08203.

              Hope this will be helpful, let me know if you need more clarification.

                    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,
                    WhatsApp Image 2024-04-12 at 10.40.06_c7d1947e.jpg WhatsApp Image 2024-04-12 at 10.40.05_897b8bb6.jpg
                    Data getting in console after integration of both lora and gps.
                    3f45cfe7-0061-4328-8c55-ef0a73385203-image.png
                    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.

                  • Hi @zainmuhammed ,

                    Can you share the GPS and LoRa output when it’s working?

                    Also can try capturing the GPS when the device is starting the loop instead after joining the LoRaWAN and see?

                    Also make sure the device provides have enough to modules. The GPS need more power when you cold start.
