Wi-Fi R-Mesh Programming Interface

Common

User Configuration File

Path: {sdk}/component/soc/usrcfg/amebaxxx/ameba_wificfg.c

Parameter	Description
wtn_en	R-Mesh enable. Set to 1 to activate
wtn_strong_rssi_thresh	Node directly connects to AP if detected RSSI exceeds this threshold
wtn_father_refresh_timeout	Child node switches parent if no beacon received within this period (in ms)
wtn_child_refresh_timeout	Parent node removes child if no beacon received within this period (in ms)
wtn_max_node_num	Max nodes in R-Mesh network. Determines beacon window size: higher node count reduces window size and increases interval

RNAT Parameters

User Configuration File

Path: {sdk}/component/soc/usrcfg/amebaxxx/ameba_wificfg.c

Parameter	Description
wtn_rnat_en	R-Mesh NAT enable. Set to 1 to activate.
wtn_fixed_rnat_node	Force device as R-NAT node. Set to 1 to enable (effective only when wifi_user_config.wtn_rnat_en=1)
wtn_connect_only_to_rnat	Only select RNAT and the subordinate nodes of RNAT as the father node. Set to 1 to enable
ap_sta_num	Max child nodes connectable when acting as RNAT. Currently supports up to 14 clients

Note

When wifi_user_config.ap_sta_num > 5, adjust memory layout as follows:

Open {sdk}/amebadplus_gcc_project/amebaDplus_layout.ld and modify RAM_KM0_IMG2_SIZE from 96K to 116K to support 14 direct clients.

#define RAM_KM0_IMG2_SIZE                KBYTES(116)
