it shows the message that no hardware configuration exist for this set up.
buzzer doesn’t generate any sound
have you entered the “GPIO type- Output” in the hardware section of the cloud?
yes i have followed all step
can you post the screenshot of configurations you have done?
First Check the Connection that you are making is right:
You need to insert the longer leg of the Buzzer (+ve) into the any of the GPIO pins which are labeled 0, 1, 2, 3, 4
and the shorter leg of the buzzer into the GND pin of the Bolt Module
after making the connection You need to create the Product on the bolt cloud with the following configurations:
1 output
2 GPIO
once done you can write the code and change the pin Voltage by using the bolt library function
digitalWrite(PIN, VALUE)
here PIN is the pin that you have connected the +ve leg of the buzzer
and VALUE is the either “HIGH” OR “LOW”
and if you want to change the sound of the buzzer you can change it using
PWM (Pulse width Modulation) using the Bolt library function:
analogWrite(PIN, VALUE)
here PIn is the pin number you have connected your buzzer longer leg to (+ve terminal)
and VALUE is from 0 to 255
and make sure that you don’t make too many requests to the bolt cloud or you will be having to deal with API requests denial for 6 hours
make every request with atleast interval of 5 seconds
i also faced this problem.the solution of this problem can be-
in product configuration section click on “hardware” click on space aside on pin ‘0’.give it any suitable variable name,doesnt matter and save it.then try again.
I still didn’t get it right.

check the hardware connections again like put the longer leg of buzzer into GPIO pin labeled as 0,1,2,3,4 and shorter leg of the buzzer into GND pin. make sure you have better network connectivity.After harware connections go to the training videos and write the code and check the code again, make product configuration,link your device.hope you will get it right.
make the buzzer connections as, longer leg into any of the GPIO pin(0,1,2,3,4) and shorter leg into the ground pin(GND) of the bolt device. Note that you don’t use any resistors with the buzzer, instead to vary the sound of the buzzer use the command “analogWrite(pin,value)”, here “pin” will be the GPIO pin connected to the buzzer and “value” may vary from 0 to 255. For further understanding refer to the “Home Automation” module of the training.
Hope you get it right.
