      @saheen_palayi Not yet, It's their first draft for the Photon 2 . No information on ETA or available countries.

      @Richu-Bini I'm not sure if this is the root cause but normally, you should add an RC delay on the EN pin. This is because the BOOT pin should reach 3.3V before the EN reaches 3.3V hence, the RC delay on the EN pin. A 10K resistor and a 1μF Cap should do it. Here's a sketch on how it should look like:

      Here is the part in the datasheet of the WROOM32 that tells you to do it:

      @Adithya-SM Can you confirm the I2C address is correct? You can use this I2C Scanner to program to find the correct address

      // -------------------------------------- // i2c_scanner // // Modified from https://playground.arduino.cc/Main/I2cScanner/ // -------------------------------------- #include <Wire.h> // Set I2C bus to use: Wire, Wire1, etc. #define WIRE Wire void setup() { WIRE.begin(); Serial.begin(9600); while (!Serial) delay(10); Serial.println("\nI2C Scanner"); } void loop() { byte error, address; int nDevices; Serial.println("Scanning..."); nDevices = 0; for(address = 1; address < 127; address++ ) { // The i2c_scanner uses the return value of // the Write.endTransmisstion to see if // a device did acknowledge to the address. WIRE.beginTransmission(address); error = WIRE.endTransmission(); if (error == 0) { Serial.print("I2C device found at address 0x"); if (address<16) Serial.print("0"); Serial.print(address,HEX); Serial.println(" !"); nDevices++; } else if (error==4) { Serial.print("Unknown error at address 0x"); if (address<16) Serial.print("0"); Serial.println(address,HEX); } } if (nDevices == 0) Serial.println("No I2C devices found\n"); else Serial.println("done\n"); delay(5000); // wait 5 seconds for next scan }

      @salmanfaris Actually, I can't connect my NodeMCU device with the localhost server. I can establish a connection using the test.mosquitto.org server.
      This is my required case: YouTube link
