Using the BlueNRG with FreeRTOS

[aj.sk]

I try to use the BlueNRG in conjunction with the FreeRTOS but the system always ends up in a hardfault as soon as I querry the BLE services.

The initialization of the BlueNRG works and establishing a connection works as well. But it seems like any user driven event crashes something.

I have 3 concurrent tasks and the BLE task has highest priority.

My assumption is that I somehow have to implement an event driven scheduler blocking but I don't know where to start.

Doubled the task's stack size, now it works

Do you have the EXTI interrupt enabled in CubeMX?
