I tried to make app for transmit a message to Arduino using Bluetooth but bluetooth is not connecting and it not transmitting the message
Is that the name of your device as it appears in the scan label?
are you able. to see this device via LightBlue?
no it not connecting
Your code does not use the error green block to see what kind of error is being generated from the
Connect to Device Name block.
Without displaying the error how would you know what is the problem with your code?
