RE: Ble Encrytion using AES

Hi Helsing,

Thank you for the reply, I am working NRF52840, which is used to send data received over UART to mobile app using uart service. I have enabled pairing and bonding, but i also need to encrypt the data sent after pairing.

When i compile the Crypto:AES i am getting this error

How do i know the data i am sending is encrypted?

Regards,

Shafi

Hello Shafi,

[quote user=""]I am working on the encrypting and decrypting the data sent/receive from ble[/quote]

Would you be able to share a little more context regarding what you would like to achieve?

Have you had a look at our Cryptography samples? If you would like to do the same as the Bluetooth stack is doing, then you could take a look at the Crypto: AES CCM sample.

All our Bluetooth samples that includes paring+bonding enables encryption when paring+bonding, for example the Bluetooth: Peripheral UART sample.
