      @kowshik1729 Yes. I am not asking you to use esp_now for communicate esp32 with mobile phone. I am saying only to use espnow protocol in order to communicate with your client esp32. It might reduce your problem. Also, read this instructables completely 👍

        @arunksoman When you told me use esp_now to communicate with client but not with mobile you mean to use BLE connection between server and mobile?

        I'm simply asking you that are you suggesting me this kind of 👇 architecture??

        Mobile to server - BLE connection

        Server to client - ESP_NOW

        Is this what you've meant bro?

          @kowshik1729 Yes, now you are absolutely right. That is what I tried to convey. The instructables given above is saying two way communication between client and server BLE is possible with android. But I didn't tried that. But I will try that soon.

            @arunksoman I have read about ESP_NOW protocol from the Espressif page and it is mentioned that ESP_Now makes use of Wifi but without any connections. Which means my power consumption obviously increases. As I am going to use this application in a wearable use case I want some power-efficient solution.

              @kowshik1729 Did you read Espressif page and datasheet completely?

              ESP-NOW is yet another protocol developed by Espressif, which enables multiple devices to communicate with one another without using Wi-Fi. The protocol is similar to the low-power 2.4GHz wireless connectivity that is often deployed in wireless mouses. So, the pairing between devices is needed prior to their communication. After the pairing is done, the connection is safe and peer-to-peer, with no handshake being required.
              Espressif ESP-NOW OVERVIEW

              "The ESP-Now protocol is connection-less, you don't need to set up a session/get an ip-address to communicate between nodes. This saves time and battery power, exactly what we need. "
              revspace

              Also You can try this protocol with deep sleep mode.

                • @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.
