Notecard accepting external wired inputs like an external button

Hi there, new user to Blues Wireless. I was wondering can the notecard or notecarrier accept a wired input like an external button and with the click of a button send the data flow to notehub? Please let me know. Thank you.

Hi @eyang and welcome to the Blues Wireless community!

I would recommend you take a look at the Notecard’s monitor mode. Using the card.monitor API you can likely accomplish what you are looking to do. However, the core design of the Notecard is based around using it connected to a host MCU/SBC and the Notecard itself acting as a cloud data pump.

Let me know if I can help with anything else!

@eyang I might be leading you down a slightly incorrect path. The card.aux API is likely what you are looking for.

In the meantime please take a look at this thread with an example of card.aux and I’ll be back with some follow-ups:


Hi Rob,

Thank you getting back to me very quickly. I took a read on the information sheet you provided and I found the closest thing to what I am looking for is the card.aux option where I physically connect the button into the board using AUX 1 - AUX 4.
