Encryption using user defined keys

[Zero.cool]

Hi Team,

We are working on project where we are trying to encrypt the advertisement data (non-connectable) using our own defined keys.

currently I have been through the links and documentation provided over website where there enough details provided.

I would like to know, if there is a way to have user defined keys for encryption instead of using methods provided for all advertisement packets weather its connectable or non-connectable.

If any example or any pointer would be useful for our development.

Thanks,

Isn't this just the same as your previous thread: https://devzone.nordicsemi.com/f/nordic-q-a/66099/encryption-in-data ?

If you're doing your own encryption, then you're just using the BLE link as a transparent pipe: to the BLE, it's just a load of bytes - the BLE neither knows nor cares anything about what those bytes represent.

Hi awneil
Yes, it relates to that, But here I am trying to check that I don't want use any algorithm provided and wanted to go with user defined key for encryption for (connectable and non-connectable) advertisement. as we have different applicaiton

exactly: if it's all your own encryption then it's nothing to do with BLE - as far as the BLE is concerned, it's just a load of arbitrary bytes.

yes, I am requesting is , is there any example or pointer which I can refer?
Any pointer Karl Ylvisaker

again, it's nothing specific to BLE or Nordic - so any general examples will apply
