help
This value sets the number the Controller will allocate for extended advertisement
instances at initialization process. If more extended advertisement instances are
enabled, those memory will be dynamically allocated.
Using reduced amount of reserved memory will save heap size at the cost of extra
time consumption at advertising start process and possible advertising start failure
due to memory shortage.
The actual reserved memory count will be the minimum value between the maximum
extended advertisement instances and the BT_LE_EXT_ADV_RESERVED_MEMORY_COUNT.

This value sets the number the Controller will allocate for connection instances
at the initialization process. If more connection instances are enabled, those
memory will be dynamically allocated.
Using reduced amount of reserved memory will save heap size at the cost of extra
time consumption at connection establishment process and possible connection
establishment failure due to memory shortage.
The actual reserved memory count will be the minimum value between the maximum
connection instances and the BT_LE_CONN_RESERVED_MEMORY_COUNT.
