Hi Jan,

I want to create a button interrupt and send notification to central when a given button is pressed.

I have tested it with your example where 2 tasks are created and controlled by using semaphore.

I was just wondering instead of creating 2 tasks, can I run the button interrupt handler within BLE application itself? Will it work or will it disrupt the BLE task and cause disconnection?

Hi,

Thank you for reaching out! With the basic_ble or datastream examples you can use the existing bleapputil task to process your interrupts and handle the button presses without having to worry about adding an additional task. To do this, set up your interrupts as normal and within your interrupt context call a helper function via the bleapputil_invoke() function to call your helper function from within the bleapputil task context. I recommend referencing the Bluetooth LE and Drivers simplelink academy as this walks you through exactly how to do this. The relevant section is shown below:

Best Regards,

Jan
