How do change the value of IRK

[summer]

I use nrf51822 to do bluetooth keyboard, I hope the function is: I want to change the IRK value of the bluetooth keyboard each time it is paired and bound,Anybody know how to do that?My tests so far have found that the IRK value is fixed for each pair binding,I want to change IRK to a random number. How do I change it? thanks!

Hi,

Once you have set the IRK as discussed earlier, this is the IRK that will be used by the stack as your own IRK, and this is the one that will be transmitted to the peer during the key distribution when bonding. So you just need to set the IRK first, then all this is handled automatically (no need to change anything in how you do bonding etc.)
