# Usage

This test provides an example for the BlueNRG-1 sleep modes. The sleep modes tested are SLEEPMODE_WAKETIMER and SLEEPMODE_NOTIMER.

- The SLEEPMODE_WAKETIMER puts the BlueNRG-1 in deep sleep with the timer clock sources running. The wakeup sources are any character typed on the keyboard, the PUSH1 button or the sleep timer configured with a timeout of 5 sec.
- The SLEEPMODE_NOTIMER puts the BlurNRG-1 in deep sleep with the sleep timer clock sources turned off. The wakeup sources are only any character typed on the keyboard and the PUSH1 button.

The demo supports some user commands:

- s: SLEEPMODE_NOTIMER - wake on uart/button PUSH1.
- t: SLEEPMODE_WAKETIMER - wake on uart/timeout 5 sec/button PUSH1.
- l: Toggle led DL1.
- p: Print Hello World message.
- r: Reset the BlueNRG-1.
- ?: Display this help menu.
- PUSH1 button: toggle led DL1.
