I'm working with ANT+ protocol, to connect a smartphone with an ANT+ USB dongle, which is connected to PC where with SimulANT+. SimulANT+ is simulating a heart-rate sensor, which sends data to my phone.
Until now I have been using a non-encrypted channel to communicate, but there is also an option to make a secure connection between devices as is written in ANT Message Protocol and Usage document. It's called Single Channel Encryption. Do someone have some code examples on how to establish this type of connection?
It is true that ANT protocol can use a single encrypted channel - however this is not the case for ANT+. (See the differences between ANT/ANT+ here: http://www.thisisant.com/developer/ant-plus/ant-antplus-defined)
If you use encryption for your device it is no longer ANT+ compliant and therefore you are not allowed to use the ANT+ Network Key or frequency.
This is because ANT+ aims to ensure interoperability between different manufacturers sensors/displays. If the channels were allowed to be encrypted, this would defeat the purpose ANT+.
Therefore if your goal is to use your device with SimulANT+ (or any existing ANT+ sensor) it will not work. In fact, SimulANT+ does not even allow the utilization of encrypted channels.
