How to wake up KW38 by BLE connect event？

yuewang · ‎10-02-2022

I use the KW38 as a BLE peripheral, and hope it can meet the following requirements:

1.Go to a low power mode when I press a key button ;

2.In the low power mode, KW38 can be scanned and connected;

3.When a central device connect the KW38, it can be waked up from the low power mode.

Is there any methons or example projects to make it？ Thanks!

Please, take a look at Heart Rate Sensor (hrs) and Temperature Sensor (temp_sens) example projects inside the KW38 SDK (wireless_examples > bluetooth). These examples could meet your requirements and may be used as a base to develop your application, they are highly configurable, allowing the user to set some relevant parameters and change the information being transmitted.

For more information about these applications, please consult the Bluetooth Low Energy Demo Applications User's Guide (inside KW38 SDK documentation folder > docs > wireless > Bluetooth).

Regards,
Eduardo.
