nRF8001 Product Specification
Revision 1.2
22.3.3 Hardware settings
Hardware settings represent the configuration of proprietary hardware specific parameters, such as:
• Clock sources and settings
• Radio settings
• nRF8001 hardware feature activation and settings (Active signal, antenna EIRP, DC/DC converter
and so on)
22.4 Active mode
Active mode handles run time operation and application data exchange. Completing nRF8001 setup is
required prior to entering Active mode.
nRF8001 enters Active mode upon completion of the setup procedure, wakeup from sleep mode or directly
from reset if the device configuration is stored in Non-Volatile Memory (NVM). nRF8001 exits Active mode
upon receiving the ACI commands
Test, Setup or Sleep.
Active mode enables the following operations and procedures to be initiated:
• Advertisement including service discovery upon connection establishment
• Bonding
• Sending application data through a transmit service pipe
• Receiving application data through a receive service pipe
• Saving and restoring dynamic data like bonding and pipe connection status
