QN908x BLE without real-time operating system

lukaswidmer — Mon, 18 Dec 2017 09:12:06 GMT

I'm trying to minimize energy consumption on the QN9080 MCU as much as possible and hence want to omit the use of a real-time operating system and the additional energy cost it implies.

I took the Bluetooth beacon example and tried to directly call the startup_task method without passing it to the scheduler. Unfortunately I couldn't receive any advertisement packets this way.

OSA_TaskCreate(OSA_TASK(startup_task), NULL);
vTaskStartScheduler();

startup_task(NULL);

How can I make it work without using the scheduler?

Hardware: QN9080 DK-V1.2 R20161129

SDK: SDK_2.2_QN908xCDK_Beta

IDE: MCUXpresso IDE v10.0.2

n Hello,

Could you please check the BLE Application Developer's Guide? You can find it under the following path:

C:\NXP\SDK_2.2_QN908xCDK_Beta\docs\wireless\Bluetooth

The next release of the QN9080 stack will have an optimization on the power consumption if that it's what you are seeking for.

Best Regards,

Estephania
