The BMD-100 is pre-configured at the factory for use with the on-module 32 MHz crystal, internal low-speed Ring Oscillator (RO), and 4-MHz Switch Mode Power Supply (SMPS). It also has a Rigado provided MAC address stored internally, however the application firmware on the Host MCU must read and enable its use.
If using the module with an external 32.768 crystal, the IFR must be reprogrammed with the appropriate parameters. Download the BlueNRG DK from STMicroelectonics for details.
The stack firmware on the module can be updated using the BlueNRG DK.
