ANT channel encryption

[Torsten Robitzki]

Hello, I'm reading S210_SoftDevice_Specification_v2.0.pdf and there is written: "The ANT channel encryption engine provides the ability for a single channel..." does this realy mean, that I can use encryption only on one single channel?

If I need more channels, do I have to encrypt/decrypt the payload on my own? If so, how would a resonable algorithm look like?

What are the reasons for such limitations and are there plans to allow more channels to be encrypted in furture versions of the SOC?

TIA, Torsten

In the current version of S210 and S310 it's only possible to have one encrypted channel on each ANT device. This may change, but we have no schedule or confirmation on that. Alternatively you would have to request and handle encryption in your application.
