ESP-MESH utilizes beacon frames to detect and resolve root node conflicts (see documentation). However 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
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
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.

The ESP32 supports SPI (P)SRAM connected in parallel with the SPI flash chip. While the ESP32 is capable of supporting several types

The ESP-PSRAM32 chip is an 1.8V device, and can only be used in parallel with an 1.8V flash part. Make sure to either set the MTDI
pin to a high signal level on bootup, or program the fuses in the ESP32 to always use a VDD_SIO level of 1.8V. Not doing this risks
damaging the PSRAM and/or flash chip.

* External RAM cannot be used as a place to store DMA transaction descriptors or as a buffer for a DMA transfer to read from or write into. Any
buffers that will be used in combination with DMA must be allocated using ``heap_caps_malloc(size, MALLOC_CAP_DMA)`` (and can be freed using a
standard ``free()`` call.)
