求大神看看这是什么问题expected identifier before ')' token

potian119

ESP8266的单路控制器。之前可以写， 后面写进去老提示：expected identifier before ')' token
是用在单路继电器控制电脑开机的。
求大神帮我看一下是什么问题？


代码如下



#define BLINKER_WIFI
#define BLINKER_MIOT_OUTLET
#include <Blinker.h>


char auth[] = "*******";
char ssid[] = "***";
char pswd[] = "********";
BlinkerButton Button1("btn-abc"); //定义按钮键名

bool oState = false;

void button1_callback(const String & state)
{
  BLINKER_LOG("get button state: ", state);
  digitalWrite(0, LOW);
  Blinker.delay(200);
  digitalWrite(0, HIGH);

}

void miotPowerState(const String & state,)
{
  BLINKER_LOG("need button state: ", state);


  if (state == BLINKER_CMD_ON) {
    digitalWrite(0, LOW);
    Blinker.delay(200);
    digitalWrite(0, HIGH);
    BlinkerMIOT.powerState("on" );
    BlinkerMIOT.print();
    oState = true;
  }


  else if (state == BLINKER_CMD_OFF) {
    digitalWrite(0, LOW);
    Blinker.delay(200);
    digitalWrite(0, HIGH);
    BlinkerMIOT.powerState("off" );
    BlinkerMIOT.print();
    oState = false;
  }

}


void setup()
{

  Serial.begin(115200);
  BLINKER_DEBUG.stream(Serial);

  pinMode(0, OUTPUT);
  digitalWrite(0, HIGH);

  Blinker.begin(auth, ssid, pswd);

  BlinkerMIOT.attachPowerState(miotPowerState);

  Button1.attach(button1_callback);

}

void loop()
{
  Blinker.run();
}

void miotPowerState(const String & state,) 多个逗号
