When building my BLE application for debug, the BLE stacks overflow and crash the firmware. Note that this happens every release of ncs. Would be great to have the stacks setup properly when full debug is built. Or AT LEAST make all the stacks configurable by users so we don't have to change the ncs sources.
Here is how I config for debug:
CONFIG_DEBUG=y
CONFIG_DEBUG_INFO=y
CONFIG_NO_OPTIMIZATIONS=y
CONFIG_DEBUG_THREAD_INFO=y
CONFIG_EXTRA_EXCEPTION_INFO=y
CONFIG_BT_HCI_TX_STACK_SIZE_WITH_PROMPT=y
CONFIG_BT_HCI_TX_STACK_SIZE=4096
CONFIG_BT_RX_STACK_SIZE=4096
# CONFIG_BT_CTLR_ECDH_STACK_SIZE=4096 # Can't be set...
# CONFIG_BT_LONG_WQ_STACK_SIZE=4096 # Can't be set...
Here are some of the BLE stacks that can't be changed via CONFIG so I had to modify ncs:
