Can we use nRF52840 connectivity chip CC310 hardware directly from application chip?

Using the CC310 hardware with serialization is not a feature that is supported by our API. It might be possible but unfortunately, this is something that you would have to do yourself.

Hi Jared,

We want to achieve below functionality, so is there any API which can be called from serialization application and connectivity chip link CC310(Nordic) HW encryption for LESC and LE Legacy?

· Send data in unencrypted form from CortexM4 to nRF52840 Nordic module. nRF52840 should be able to encrypt the data and send to Mobile Application.

· In the similar way, when the encrypted data is sent by the Mobile App, nRF52840 module shall decrypt this data and send to Cortex M4.

· Cortex M4 will maintain the key and can send to nRF52840 during initial exchange.

· Cortex M4 will only handle the data and will not do any encryption or decryption of packets.

Thanks,

Pintu

Hi,

Serialization gives only accesses to the softdevice API not the peripherals of the nRF52, which means that it doesn't support the access to the CC310.

Best regards
