How is the white list size defined in Bluetooth LE?

[Bruno Hars]

Neither in BLE core specification nor in your documentation I found a hint, how the size of white list is defined and what the limits are.

At the Link msdn.microsoft.com/.../jj134352.aspx I found following statement: "Bluetooth controllers must support a minimum LE white list size of 25 entries." The limit seems to be chip-specific. But is that statement true?

Questions:

• Is there a minimum size defined for BLE white list?
• What are the white list size limits (upper / lower) at Nordic Chips?
• Is the white list size configurable or fixed?
• May Centrals and Peripherals use the full size of white list?

Thanks for reply

The S110 supports a whitelist of up to 8 addresses and 8 IRKs. There is no minimum size, and in fact, when you want to bond to a new device, you need to make sure that you don't use a whitelist at all.

You can't change the maximum size of the whitelist, but you are free to fill as many items as you'd want to, i.e. from 0 to 8.

May I ask what you actually try to achieve?
