使用稳压器安装 3.3v im。
RX 也连接到 RX 和 TX 到 TX。
代码:
#include <ESP8266WiFi.h>
void setup()
{
Serial.begin(115200);
Serial.println();
WiFi.begin("username", "password");
Serial.print("Connecting");
while (WiFi.status() != WL_CONNECTED)
{
delay(500);
Serial.print(".");
}
Serial.println();
Serial.print("Connected, IP address: ");
Serial.println(WiFi.localIP());
}
void loop() {}
有人建议将GPIO0接地,没有用。
尝试安装不同版本的主板:“通用 ESP8266 模块”仍然出现相同的错误。
该模块在没有使用 Board 的库的情况下工作正常:“arduino uno”
