Softdevice Task crash on disconnection

[lcalvez]

Hi,

I am developing a product based on nrf52832 using FreeRTOS and the softdevice.

I use sdk 15 and I based my softdevice configuration on the ble_app_hrs_freertos example. My problem is that on a disconnection event the device does not start to advertising as it should. The application is still responsive except for the softdevice task. 
I managed to make it work by changing the size of the buffer I use to store data I received from NUS service. This fact made me think I had a memory issue but I was not able to find an error on this side.

I did not find any topic related to this issue in the forum so I wonder if anyone experienced this kind of issue or if you have an idea of what could be the cause.

Thank you!

try to set a memory write watch point on write condition on address 20004D8 and see when and which context corrupts it. It will give you the context of where the error is happening.

Thanks I found it. I was writing in an array at an index out of bounds. I would not have found the error without the watch point.
