Module esp_now 

Structs

Channel

A 2.4 GHz channel ESP-NOW can park on, constrained to the globally legal 1..=13 set.

Enums

ChannelPolicy

Where a node’s ESP-NOW channel comes from. A node associated to an access point is channel-locked to that AP and must not retune (retuning would break the association), so it follows the station; a node not associated is free to park on a fixed rendezvous channel.

Constants

CHANNEL_TAG_CAP

DEFAULTS

ESP_NOW_BITRATE_BPS

A representative broadcast goodput for announce pacing and the MTU tier — an honest order of magnitude for the carrier, not a measured peak.

ESP_NOW_HW_MTU

The clean-packet MTU we declare: the air ceiling less the largest access tag, so a full frame plus its IFAC code still fits one ESP-NOW datagram.

ESP_NOW_V2_AIR_MTU

ESP-NOW v2’s on-air payload ceiling (ESP_NOW_MAX_DATA_LEN_V2). The radio fragments and reassembles beneath this, so a frame up to here crosses whole.
