123 / 132 page  DocID027514 Rev 1 123/132 UM1865 Vendor specific commands 132 Event(s) generated: The controller will generate a command complete event. 4.7.9 Device_Standby Description: Normally the BlueNRG-MS will automatically enter sleep mode to save power. This Device_Standby command further put the device into the Standby mode instead of the sleep mode. The difference is that, in sleep mode, the device can still wake up itself with the internal timer. But in standby mode, this timer is also disabled. So the only possibility to wake up the device is by the external signals, e.g. a HCI command sent via SPI bus. Based on the measurement, the current consumption under sleep mode is ~2 uA. And this value is ~1.5 uA in standby mode. The command is only accepted when there is no other Bluetooth activity. Otherwise an error code “command disallowed” will return. Event(s) generated: The controller will generate a command complete event. 1 3 -5.1 1 4 -2.1 1 5 1.4 1 6 4.7 1 7 8.0 (default) Table 287.
