This case is over one year old. I would suggest that you create your own ticket where you describe your inquiry/problem in detail, and possibly link to this case if you find that it is relevant to your case.

If you want to send data over the air using BLE for example, I would suggest you look into the ble_app_hrs example in our SDK, which demonstrates the use of Low Energy Secure Connections (LESC).

Best regards,

Simon

Hi,

How to encrypt the data that is to be sent from the device to an app?

[quote userid="80515" url="~/f/nordic-q-a/49984/sending-encrypted-data-over-ble"]What re the changes that i have to make to the RX Characteristic of the NUS in order to be able to receive Encrypted data[/quote]

None at all!

NUS is just a "pipe": bytes go in, and the same bytes come out again at the other end - it neither knows nor cares what those bytes represent.

Of course, after the bytes have been received you would need to de-crypt them - but that's nothing to do with NUS.
