What mechanism randomizes the BLE address that gets hashed with the IRK?

I can't seem to find where/how the BLE address gets randomized so it changes periodically when using the BLE_GAP_ADDR_TYPE_RANDOM_PRIVATE_RESOLVABLE address type.

-It seems trivial to manually change the address but how about the hashing of this address with the IRK?

-Is this mechanism exposed outside the softdevice?

-Does the softdevice support this address type?

Thanks!

Hi Anders, The S110 currently use BLE_GAP_ADDR_TYPE_RANDOM_STATIC address type. EDITED: the following information provided earlier was not correct. [u] As you know you can set BLE_GAP_ADDR_TYPE_RANDOM_PRIVATE_RESOLVABLE…

Dear Hung Bui,

We are also interested in this function for our projects using nRF51822. Do you have any update for S110 version?

"This may change in S110 v7.x, but I can't say for sure when it will be available."

Best Regards, Matt

Hi Matt, It's is supported on S110 v7.0 production. You can have a look at the release note to find more information. Please note that to add the custom IRK in you would need to use the sd_ble_opt_set API.
