Trying to communicate from one ESP32 to another ESP32 ,with one acting as a AP and another acting as Client but cant seem to connect the esp client to the esp AP, but connecting to AP using my smartphone works.Sorry if this seems to be a simple questions, I am new to esp32s and ...
strncpy ((char*)wifi_config.sta.password, (char*)password, sizeof(wifi_config.sta.password)); if (wifi_get_authmode(&wifi_config.sta.threshold.authmode, ssid) != false) { ESP_ERROR_CHECK(esp_wifi_set_config(WIFI_IF_STA, &wifi_config) ); ESP_LOGI(TAG, "wifi_init_sta finished.")...
we want to try connect ESP32 with STM32 via UART using the ESP_AT after flashing the esp32-wroom-32e with esp-at firmware (ESP32-WROOM-32-V2.2.0.0), the output from UART0(USB in dev-ket) is as expected (figure1). figure1.png But we couldn't communicate with the ESP32 via ...

WiFi.disconnect(); WiFi.reconnect(); previous_time = current_time; } } You can increase the recheck time by changing the delay value in the following line: unsigned long delay = 20000; // 20 seconds delay This method is a good solution to reconnect WiFi to ESP32 if the connection loses...
这篇教程将带领大家了解如何在两个 ESP32 板之间建立 BLE(低功耗蓝牙)连接。一个 ESP32 将成为服务器,另一个 ESP32 将成为客户端。BLE 服务器通告包含客户端可以读取的传感器读数的…
本人想用esp32读取串口数据并且通过MQTT协议传到公共服务器端,但出现了下面的问题: (1)如果将串口设置波特率为115200,则能够立马连上wifi和服务器,但是读取不了串口数据发不上服务器端。 因为所连接开发板传…
在eps32c6上同时使用espnow和wifi station问题描述 投票:0回答:1我从stackoverflow 获得了很多帮助,但这是我第一次提出问题。我的问题是这样的:使用espnow通信在两个esp32c6开发板之间成功传输数据。但是,如果将两者之一更改为 wifi 站并尝试连接外部互联网,espnow 通信将失败。不管怎样,独立运行时是不会出现故障...
一、概述 通用异步收发送器(UART)是一种硬件特性,它使用广泛适应的异步串行通信接口(如RS 232、RS 422、RS 485)来处理通信(即时序要求和数据帧)。UART...
