Struct EspNowSender

pub struct EspNowSender<'d> { /* private fields */ }

Available on crate feature unstable only.

This is the sender part of ESP-NOW. You can get this sender by splitting a EspNow instance.

You need a lock when using this sender in multiple tasks. DO NOT USE a lock implementation that disables interrupts since the completion of a sending requires waiting for a callback invoked in an interrupt.
