Hack Heart Rate Monitor (or other) nRF code by adding tone or beep command when using nRF Toolbox app.

[DaleScott]

I tested the Heart Rate Monitor sketch code (Arduino Primo IDE code) and verified that it works with the Heart Rate Monitor through the "nRF Toolbox app" on my iPhone. I would like to change my Arduino code to add the capability to send a command via the Arduino code to cause a notification tone, beep or other audible sound on the iPhone.

I noticed on the iPhone that the nRF toolbox has "notify" capability. So I'm hoping there is some simple command or set of commands to get this to happen.

Please advise or provide useful links.

I do not see any buttons to push to close this case. Supposed to be in top right corner, right?

I can close the case for you. I am unsure whether you are able to close the case yourself.

Please do.
