    @Anudeep Thanks a lot m8, I actually made a very silly mistake of including the https:// while entering FIREBASE_HOST, where I must have entered the Domain name alone and removed the https:// extension.

    Thanks again for replying that quick. Cheers.

    Hello @Palani, In the Firebase, there are two types of storage,

    Cloud Firestore (Very recent one & NoSQL database) Realtime Database (To which we upload the data using NodeMCU)

    In the Arduino Code, you can see that there is a variable named FIREBASE_AUTH.

    This variable should be assigned to the Database secret. This you can find in Project Settings -> Service accounts -> Database Secrets.

    My mistake is, i have mistakenly assigned thay to Web API key. This is found at Project Settings -> General.

    The error can also occur when u don't initialise a proper realtime database in Firebase. (This is not my case).

  • @kowshik1729 If you are using an external high-speed switch, there is only one one clock generator for both wifi and BLE and the high-speed switch you mentioned is Ultra-Wideband (UWB) 3โ€“8 GHz from its datasheet

    you also check this solution that I shared in the previous post.

    @salmanfaris said in BT and WiFi Dual Core simultaneous operation using ESP32?:

    There is a special option called โ€œSoftware controls WiFi/ Bluetooth coexistenceโ€ it can control the ESP32's Bluetooth and Wi-Fi coexistence using software, more details: https://www.espressif.com/sites/default/files/documentation/ESP32_FAQs__EN.pdf
