I just recently decided to do some work within the course “ANDROID APPS FOR ARDUINO with MIT App Inventor 2”.
I was thinking of replacing the Arduino and the HC-05 Bluetooth module with the ESP32 since the ESP32 has BT built in.
At least I’d have to replace the Arduino serial in data (from the HC-05) with code to get BT data directly from the phone.
Do you think it’s rather straightforward to do the Arduino/HC-05 replacement with the ESP32?

Hi.
I haven’t tried it. But, I think it is if you use Bluetooth Serial with the ESP32:

Sara,
Just after I asked this question, I thought “what the hey” — I’ll just try it.
Well, it is as you say (straight forward) if one uses BTSerial with the ESP32.
I was a little surprised how easy it was, but I guess I shouldn’t be since that is probably the real value of Bluetooth serial.
I see that things change with time (rather insightful, isn’t it?) as I went through the MIT AI2 development process.
The changes were not so drastic as to make it really hard to follow the tutorial.
I particularly like this tutorial because of MIT AI2 — it’s pretty nifty.
As always, thank you guys for the excellent work you do!
Ray

That’s great.
I’ll mark this issue as resolved. If you need further help, you just need to open a new question in our forum.
