      @abdultechguy999 Can you share the Board URL you using? it might be the wrong board URL!

        @salmanfaris I tried three types which I all found on the net
        https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

        https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_dev_index.json

        https://dl.espressif.com/dl/package_esp32_index.json

        All I keep getting is an error message
        'Error downloading [the link]'

          @abdultechguy999 It looks like Arduino IDE having trouble to connect internet, can you try to download any other board from the board manager or library from the library manager!

            @abdultechguy999 usually https://dl.espressif.com/dl/package_esp32_index.json this works while installing through boards manager. But I faced the same issue some times. it might be due to a couple of reasons.

            1. Bad Internet connectivity

            2. The license of the https://dl.espressif.com/dl/package_esp32_index.json might be expired(If this is the reason you can't do anything but just wait until they re-activate the license)

            I remember there is a way to install the board files offline by downloading from some github repos.

            All the best.

              • @mahesh02 From the current Arduino ESP32 board files, we don't need to install the ESP-NN separately.

                But try to choose the esp32 board version 3.1.3 and check, as I also faced issues with the latest esp32 board file.

              • This also happened to me when I was given a task from my company, So what I can recommend is:
                Ensure that the correct board, "AI Thinker ESP32-CAM," is selected in the Tools menu of your Arduino IDE.
                If the board is not listed, you may need to install it through the Board Manager. Search for "ESP32" and install the latest version.
                Ensure that necessary libraries like ESP32-CAM, WiFi, and HTTPClient are installed. You can install them through the Library Manager.

                Carefully check your code for typos, missing semicolons, or incorrect syntax.
                Verify that you're using the correct function names and parameters.

              • Hi @PumpedMedusa, The rage is depends on the Antenna and how much TX power you have.

                To choose antenna, first you need figure out - where your nodes will be, take a look at the below image. The antenna act like a "torch" if you have more dbi that mean it's focus will be increase and it can reach more distance but the angle it have it less, like a laser.

                458a3da2-175a-4968-917c-56c5a1b763f8-image.png

                also, obstacle such as buildings, tress and mountains will affect the signal and deplete it.

                afe5eba4-b192-4263-8596-80c912fc1f23-image.png

                So, answer for you question - What is the best LoRa module to use for long distance network? - It's really depends on where you planning to put the nodes and how high you putting the gateway. Let me know know your thoughts.
