Constant latency hotfix module

Enable the constant latency hotfix module to use a device configuration with constant latency interrupts. This reduces the interrupt propagation time, but increases the power consumption.

See the Overview: Firmware architecture for more information about the event-based communication in the nRF Desktop application and about how to read this table.

Configuration

Enable the module with the CONFIG_DESKTOP_CONSTLAT_ENABLE option.

You can set the CONFIG_DESKTOP_CONSTLAT_DISABLE_ON_STANDBY to disable the constant latency interrupts when the device goes to the low power mode (on power_down_event). The constant latency interrupts are reenabled on wake_up_event.
