I have also been searching for this information. The datasheet does not have it and I cant find it in any application notes.

Are you designing with BlueNRG? That would be an obsolete product.

Or actually you were asking about one of BlueNRG-MS, BlueNRG-1, BlueNRG-2, BlueNRG-LP?

It is the BlueNRG-MS. Don’t worry. The application note covers both BlueNRG-MS and BlueNRG-1.
