Creating a BLE Custom Profile
4. For this project, the IMO frequency (High-Frequency Clock) is reduced from the default 48 MHz to 12 MHz for a lower
power consumption, as shown in Figure 31. Keep other clock configurations at their default values, and click OK.
Note The CPU clock frequency set here will affect the overall power consumption of the device. In addition, some
peripherals require a minimum clock frequency to work correctly. Choose a CPU clock frequency to keep the power
consumption low while not hindering the operation of the project.
