In this case I recommend that you check the data with the sniffer mentioned below, that should prove that the BLE traffic is encrypted on the air.

What I want is the encryption provided by BLE, and it is automatically encrypted without the other party having to implement separate encryption.
The reason I want to use encryption is to protect our data.
If so, I think the nordic app should also be encrypted. So I thought the implementation was wrong and asked a question.

Thank you

Hi,

[quote user=""] When I found and tested the ble_app_hrs project, I got data that was not encrypted as shown below.[/quote]

I think the app will decrypt the data when it is received.

I suggest that you try to sniff the data on the air with the Bluetooth Low Energy nRF Sniffer for Bluetooth LE and see if it is encrypted on air.

Of course, you can also encrypt the data before you send it over the encrypted Bluetooth connection. In that case your app will have to have custom logic to decrypt the data. Is this what you want?
