How to increase stack size for SDK on RTOS

[wty]

I'm using nrf52832 SDK17.0.2 S132 with FreeRTOS. I run into some stack overflow problem.I added DIS,BAS,NUS and DFU to my project,and if try to read DIS charistics on my phone with BLE Scanner, the stack usage goes as high as 1500 bytes. With default stack size of 1024 bytes, the program crashes sometimes. So I want to increase the stack size. But a fixed size is written in the SDK. Is there any way to extend the stack without editing the SDK? or is there any plan to add an configuration for this?

Hello,

In which file is this configuration located? I can't seem to find anything that has a default value of 1024 bytes in the SDK example. If it is in the FreeRTOSConfig.h header, then you can make a copy of it and keep it in your project directory.

it's in nrf_sdh_freertos.c , #define NRF_BLE_FREERTOS_SDH_TASK_STACK 256 (in words, so actual size is 256*4 bytes)

Yes, this option should have been exposed in sdk_config.h as it needs to be user configurable. I will report this. For now, you will either have to modify the file, or make local copy of it that you include with your project.
