can we connect gsm and blutooth at same time to any arduino board
Hey, on circuito.io it’s not possible to connect more than one component that’s labeled as a connectivity component, but it’s an technical restriction of the app. With the actual hardware, it is possible to connect both bluetooth and gsm modules to one board. It’s recommended to use a stronger board such as the mega for optimal performance, although an Uno can probably do the job as well. You can see how to connect each component separately on circuito.io and also use the test code from circuito.io and make the adjustments yourself.
If you need any help, we’re here
