![]() Error while making the Arduino IDE or PictoBlox code: For getting data from the app it is mandatory to call function “ Dabble.processInput()” in the void loop() as this function checks the availability of data and also processes the received data.The major reasons possible for this are mentioned ahead: This is because whenever any of the hardware connects to the Dabble app there is a handshake signal between Dabble and hardware wherein app requests for the identity of the board and board sends its identity to the app. If the board name is appearing correct then there is no issue in communication between hardware and Dabble app. You can check the same thing by going to the settings by clicking on the settings button in the app. This mainly happens because of improper data transfer between the app and hardware. You can check if there is any data transfer issue by checking the board name that appears as a notification as soon as your hardware connects to the Dabble app. Sometimes it may happen that your code is not working properly or not working at all. The Dabble app can connect with the classic Bluetooth (BT 2.0) HC-05 and BLE HM-10 or ESP32. This happens if you try to connect to a device that is not supported by the Dabble app. Sometimes even if the module is available in the list there is still a connection failure.You are not able to connect to the selected Bluetooth module.Or if you know the address of your Bluetooth module then connect to that address. In this case, wait for a little while longer until the name of the module does not appear on the list. In such cases, though the Bluetooth of your hardware is present in the list you cannot identify it because the name is not visible. Many times it happens that your smartphone takes time in finding the nearby Bluetooth devices.However, for ESP32 the BLE is configured from Dabble code and hence does not require any PIN to pair. Or if you don’t know the PIN then you can try some default PINs for these modules. Enter the PIN for your HM-10 or HC-05 module if you have set any PIN through AT commands. Note: Sometimes while pairing Bluetooth you will be asked to enter the PIN. This problem can occur due to the following reasons: Your Bluetooth module is not visible in the Dabble app when you see the list of all the Bluetooth devices available.Other: Error in working with specific Bluetooth modules and hardware.ĭabble is not connecting to the Bluetooth Module.Dabble code compilation error in Arduino IDE.This mainly happens because of improper data transfer between the app and hardware. Communication error: Sometimes it may happen that your code is not working properly or not working at all.Dabble is not connecting to the Bluetooth.The solution of the following most frequently faced problems that have been discussed in this troubleshooting guide (Click on the problem to jump onto it): If you are using PictoBlox for uploading code in hardware, then make sure you have the latest PictoBlox version.Dabble library for evive, Arduino Uno, Mega, and Nano.If you are using Arduino IDE for uploading code in hardware, then use the latest library for the following boards:. ![]() Make sure you have all the following resources updated: But before moving ahead you should have all Dabble related utilities updated. ![]() But no Worries! this documentation will guide you in solving your issues with the Dabble app. These problems may be related to the connection between the app and hardware, improper data transfer or error in the Dabble code of hardware board. While using Dabble with your hardware board, you may face some problems.
