Hi, I was trying to understand something more about the nano 33, I read some posts related to my question but I couldn't get a clear answer.
The question is, once connected to an app can I send commands to another board via serial? I was able to use the nano 33 to perform actions via bluetooth but I would need to manage a board that has more pins.
For example app sends '1' to nano33 which sends '1' to arduino mega which performs an action.
Would this be possible? if yes could you show me the sample sketches for both boards?
Thanks for your attention.
