Macro Definition Documentation

BACKUP_RAM

#define BACKUP_RAM   __attribute__((section(".rtc.bss")))

Declare the heap_stats function as available.

Only if module esp_idf_heap is used, a platform specific heap_stats function has to be used.

Memory marked with this attribute is retained during deep sleep and initialized with 0 on cold boot.

Definition at line 39 of file cpu_conf_common.h.

ESP_NOW_KEY

#define ESP_NOW_KEY   (NULL)

Key used for the communication between ESP-NOW nodes.

The key has to be defined to enable encrypted communication between ESP-NOW nodes. The key has to be of type uint8_t [16] and has to be exactly 16 bytes long. If the key is NULL (the default) communication is not encrypted.

Please note: If encrypted communication is used, a maximum of 6 nodes can communicate with each other, while in unencrypted mode, up to 20 nodes can communicate.

Definition at line 85 of file esp_now_params.h.

ESP_NOW_PRIO

#define ESP_NOW_PRIO   (GNRC_NETIF_PRIO)

The priority of the ESP-NOW netdev driver thread.

Should not be changed.
