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

- Internal IRAM memory wherever applicable else internal DRAM

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.
