Random hardfault when calling ble_advertising_start during task event

[Darren Chiu]

Hi support team,

I am developing a product. The product needs read adc and restart advertising when no connection.

I get hardfault randomly when called the ble_advertising_start. The hardfault was happened in vListInsertEnd.

I try to remove "identities_set" and look likes work fine. I think there have some risk when I removed it.

I modified the sample code "ble_app_hrs_freertos" and reprodcued the issue. 

SDK version: nRF5 SDK v16.0.0

Softdevice version: s132_nrf52_7.0.1_softdevice

Device: nRF52 DK

It is a bit hard for me to debug the gcc project so I made a SES project to work with your changes for PCA10040(nRF52832) DK

ble_app_hrs_freertos_sunu.zip

The only change I did is to start advertising after the disconnected event. And I do not see any hardfaults so far. Please give the SES project a go and see if you see the same? If yes, then there must be something with the gcc compiler settings that might be causing your hardfault.

I download SES and build the project. The issue cannot be reproduced with the debug/release build.

I will check the difference of build configuration.  Thanks.

Good to hear that it worked with SES. There must be some configuration difference in the two builds.  I hope you find it :)
