ESP-NOW协议本身可能存在一些问题，导致数据包被重复发送或接收。你可以尝试修改ESP-NOW的配置，例如调整...
Occasionally the send cb is not being called which causes a lockup. I can mitigate this problem with a timeout if need be but it seems as though the call back should be called. Code: Select all esp_now_send is being called from more than one task. Is Code: Select all esp_now_se...
It takes more or less exactly three timer cycles between esp_now_send() is called and the callback function is triggered. (i call millis() before sending and in the first line of the callback function and output the difference. it's always the same.) I'm wondering why? On the ...
我采用的开发板是ESP32系列ESP-WROVER-KIT,idf版本是master4.4.1 比如我在发送端每间隔1秒就用ESP_NOW_SEND发送一个unit_8型的1,接收端使能CSI并在CSI回调函数中打印出原始CSI数据等。 大多数情况下发送端间隔一秒发一个数据,接收端也只打印一个CSI,但有时候却能收到多个CSI,并且这多个CSI指向的数据来源也都...
Does this mean, if I do not care about the packet order and the sending status, I could call esp_now_send arbitrarily? Thanks 1 post • Page1of1 Return to “General Discussion” Jump to Who is online Users browsing this forum:Baidu [Spider],Bonebeast,ok-homeand 62 guests...

Learn how to use ESP-NOW communication to send data from one ESP32 to multiple ESP32 or ESP8266 boards (one-to-many configuration) programmed using Arduino IDE.
esp_now_send is being called from more than one task. Is Code:Select all esp_now_send thread/task safe? Is there a known scenario that would cause the send cb to not be called? Did you check the return value of esp_now_send?
