The following examples cover typical powersave scenarios. The command interpreter ignores a space character, but it still wakes the device.
When setting UART powersave mode to WAKE_EXTERNAL and using a pin interrupt on the RX pin, a delay may be required to allow the device to wake up before receiving bytes.Īt 115200 baud the device starts quickly enough to receive the first byte.Īt higher baudrates, you can insert space characters before commands. The device may take up to 20 microseconds to wake up. Other buses that restart the idle timer are SPI, I2C and Ethernet. If you are continuously transmitting and/or receiving bytes on the UART, with a time between bytes shorter than the idle timeout, then the device does not sleep and no power is saved. Timeout restarts every time a byte is transmitted or received on a UART. Idle timeout should be minimized to reduce overall power consumption. Power must be completely removed from the board. The device must be power cycled after programming for low power modes to work. Note: Low power modes do not work immediately after programming the device (including initial setup using GSS).

Gecko OS commands can be entered manually via a Gecko OS terminal or automatically by a host MCU system. These are managed by the system variables and other commands and variables, as follows: Configuring Command API Format System functions cover the configuration, status and control of a number of miscellaneous and loosely coupled features.
