whitelists data clearing when restart application in S110 and SDK10v

[NIDHIN K]

i have created whitelists for filtering connection its working fine now, but  when i restart my firmware the stored whitlists data become cleared so  i need to  bond each time after firmware restart its not good in my application so my question is,

i can store whitelist details( irk_count, addr_count, pp_addr , pp_irks) in my external flash memory (i'm using an external flash ) and once restart firmware i can read the data from flash memory and stored  whitelist/bond information to whitelist in initialization process . is it possible or not?

This is really up to you, but there is no problem to store the IRK and ADDR in internal or external flash as you see fit. Typically though these parameters are already stored in the peer manager, which typically handle bond information, both in central and peripheral role. So if you have to bond each time you restart, it may seem you have not included peer manager. If you want to provide the IRK and ADDR without peer manager, then make sure to set the adv_params with the specific values before calling sd_ble_gap_adv_start().

Hello, this depend whether you are using SDKv11 (or earlier), or SDKv12 (or later). Typically you will be using the persistent storage (pstorage) module or the flash data storage (fds) module. I believe there should be some examples here in devzone in either cases, you may also get some help from the documentation in the SDK you are working on.
