esp_wifi::esp_now

Struct EspNowSender

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

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.

Implementations§

Source§

impl EspNowSender<'_>

Source

pub fn send_async<'s, 'r>( &'s mut self, addr: &'r [u8; 6], data: &'r [u8], ) -> SendFuture<'s, 'r>

Sends data asynchronously to a peer (using its MAC) using ESP-NOW.

Source§

impl EspNowSender<'_>

Source

pub fn send<'s>( &'s mut self, dst_addr: &[u8; 6], data: &[u8], ) -> Result<SendWaiter<'s>, EspNowError>

Send data to peer

The peer needs to be added to the peer list first.
