      Hi @kowshik1729 , The connection between the CP2104 and ESP01 seems looks ok, can you share a more clear picture of the Automatic IO, EN toggling Circuit. Also double-check the trace continuity with a multimeter too.

        @salmanfaris oh no....the UART Bridge is not for the ESP-01. There is an ESP32-Wroom SoC, and yeah I shall share more info.

                The hotel I work at recently came under new ownership, and they’re planning to implement a housekeeping uniform policy soon. We’re a small property, just 5 floors, with about 10 housekeepers working weekends, and, there’s been no dress code.

                Right now, I wear black T-shirt, pants, apron and tennis shoes. They’re thinking about switching to housekeeping dress, but I’ve never worn them before. I’m not sure if they’re actually comfortable or suitable for active, hands-on cleaning tasks.

                Are housekeeping dresses or hotel housekeeping uniforms typically more practical? I’d love to hear from anyone with experience. If dresses actually work well as staff uniforms, please tell me, where’s a good place to get a set on my own?

                Thanks in advance for any suggestions!

                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.
                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.
