Port NimBLE Host Stack on ESP-IDF
2019-06-25 01:03:58 +00:00
NimBLE: Use dynamic buffers instead of static memory. 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

prompt "Memory allocation strategy"
default BT_NIMBLE_MEM_ALLOC_MODE_INTERNAL
help
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
NimBLE: Add support to IRAM allocation strategy Added IRAM allocation provision under nimble_platform_mem_malloc()
2020-03-18 08:23:12 +00:00
- Internal IRAM memory wherever applicable else internal DRAM

2020-01-22 16:55:51 +00:00
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.

Allows to use IRAM memory region as 8bit accessible region.
Every unaligned (8bit or 16bit) access will result in an exception
and incur penalty of certain clock cycles per unaligned read/write.
