CONFIG_ESP32_WIFI_SOFTAP_BEACON_MAX_LEN
Max length of WiFi SoftAP Beacon
Found in: Component config > Wi-Fi
ESP-MESH utilizes beacon frames to detect and resolve root node conflicts (see documentation). How-
ever the default length of a beacon frame can simultaneously hold only five root node identifier structures,
meaning that a root node conflict of up to five nodes can be detected at one time. In the occurence of
more root nodes conflict involving more than five root nodes, the conflict resolution process will detect
five of the root nodes, resolve the conflict, and re-detect more root nodes. This process will repeat until
all root node conflicts are resolved. However this process can generally take a very long time.
To counter this situation, the beacon frame length can be increased such that more root nodes can be
detected simultaneously. Each additional root node will require 36 bytes and should be added ontop
of the default beacon frame length of 752 bytes. For example, if you want to detect 10 root nodes
simultaneously, you need to set the beacon frame length as 932 (752+36*5).
Setting a longer beacon length also assists with debugging as the conflicting root nodes can be identified
more quickly.
