Hi Kim, I mean both. The module contains the Bluetooth LE stack and the classic Bluetooth 2.0 stack. So you have access to BLE + BT2.0 stacks - not the Classic Bluetooth 4.0.
And Tobi, you are right it is X.509 of course - my mistake.
Is x.502 certificate right, and not x.509?
dont you mean bluetooth 4.0 and not 2.0? BLE was not available in 2.0
