      Hi all,

      I have made a custom board with Atmega328P SMD IC and now I am having a problem flashing it. I have flashed multiple chips like these earlier, however this time I am having a hard time figuring out the issue.

      I am using Arduino UNO as an ISP programmer to burn bootloader but getting responses like Attempt 1 of 10 - stk500() is not responding etc., like that. I need some help regarding this issue.

      Any kind of help will be greatly appreciated. Please ask me for any additional information that I might have not mentioned in this post.

      Thanks in advance.

        @kowshik1729 Did you double-checked the ISP Pins connection? I also faced similar issue because of cold solder joints. also if possible can you share the ICSP connection diagram and the methods you used to flash!

          @salmanfaris I am using Arduino UNO as ISP programmer.(General ISP connections are made). I used both Arduino IDE and also avrdude command line to burn the bootloader. I am sharing link to pictures and debug outputs I got on both avrdude and arduino here. Please check it and let me know if it rings any bells for you.

            So today, I was reading about a kid who got a custom prosthetic arm printed like really. Holly molly! People are printing prosthetics nowadays! That’s when I stumbled upon Curewith3D, and wow, 3D printing in healthcare is on another level.

            Apparently, I found out that they’re not just 3d printing limbs. They actually use patient-specific scans (like CT/MRI data) and some DICOM files to design prosthetics that fit the person’s body perfectly. Every angle, curve, and dimension is matched to the individual. No more bulky or uncomfortable fits.

            What’s wild is how fast and affordable the process is. Instead of traditional molds and weeks of waiting, Curewith3D can design, print, and deliver a customized prosthetic in a fraction of the time.

            I didn’t know 3D printing services could be this life-changing, and it's happening right here in India. It really makes you wonder what else we’re going to be printing next.

            Anyone else heard of this or know someone who’s used a 3D printed prosthetic? Would love to hear more.

            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?

            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.
