[CYW20819] About encryption key and key length

[YoJa_3107936]

Hi

Could you list the encryption key name and key length for CYW20819?

AES 128bit is described on the data sheet.

Is BT E0 128bit also available?

Please tell me everything else.

Thanks,

Yang

Why do you have the question? What's the application scenario?

Is it for BLE or BT?

You may refer to the parameter wiced_bt_device_sec_keys_t in wiced_bt_dev.h.

[YoJa_3107936]

We will submit the parameter sheet to the customer.

It is necessary to describe in the parameter sheet.

Should not be checked on the source code.

[Owen_Zhang123]

Which encryption key do you refer to? There are many keys during the BLE and BT connection/data transfer. They are defined in the bluetooth spec.

Thank you for your cooporation.

Sorry, I think this is not a technical issue and is related to logistics, so please assign a person in charge of export control.

I think they know what to fill in.

Hi,

Sorry, nobody from logistics department working in this Developer Community, would you please create a "Customer Service" mycase where you could get support for this matter? The other option is contacting your local Cypress sales office.

Thanks

Roy
