Replacing wired switch by bluetooth switch

[Olivier Scalbert]

Hi,

I am working on a project where there are moving devices. Devices can only move if a wired button is pressed. In fact, for security reasons, there are two buttons connected in series to a PCL.

We would like to replace the wired connection by a bluetooth connection, that is why we are looking around about the nRF51822. We have several constraints:

• there are several sets of (switch, moving device). They are not at the same location, but it is mandatory that a remote switch is dedicated to one moving device and one only !
• safety: communication should be safe and encrypted to avoid hacks;
• low energy aspects for the switch side.

Any info or pointers to ideas, design patterns that can be used for this project would be greatly appreciated !!!

Thanks in advance !

Olivier

Ok, thanks !

So my plan is to build and test nAN-36, with one eval board and a Android machine. Then I will "replace" the Android by the second eval board with s120. Do it make sense ?

Thanks,

Olivier

Yes, that makes sense. For a quick test, you can either use Master Control Panel on Android or on Windows.
