The NimBLE host buffers that consume a significant amount of memory are now allocated dynamically. The advantage is that, the memory can be reclaimed in cases where BLE is turned off and not required for the current boot cycle

|
Allocation strategy for NimBLE host stack, essentially provides ability to
|
|
allocate all required dynamic allocations from,
|
|
|
|
- Internal DRAM memory only
|
|
- External SPIRAM memory only
|
|
- Either internal or external memory based on default malloc()
|
|
behavior in ESP-IDF
|
|
|
|
Recommended mode here is always internal, since that is most preferred
|
|
from security perspective. But if application requirement does not
|
|
allow sufficient free internal memory then alternate mode can be
|
|
selected.
