Question

我正在使用ESP32接收原始红外信号，并使用mqtt协议将其发布到服务器。服务器收到IR信号后，会将其发送回ESP进行传输。

我能够在收到信号后立即成功发送信号（控制设备）。但是，当从服务器接收到IR数据时，它不会成功传输。我从https://github.com/curlyz/ir-remote-upython-esp32/blob/master/remote_v2.py

处获取了IR代码

Remote类的一部分：（注释掉的行发送正确的信号）

    def _routine(self):
        while True:
            sleep_ms(200)
            if ticks_diff(ticks_us(),self.prev_irq) > 200000 and self.length > 0 :
                print('DECODED = [{},{}] '.format(self.decode()[1],self.length))
                payload = {"buffer":self.buffer, "length":self.length,"prev_irq":self.prev_irq}
                client.publish(b"remote/payload/123", json.dumps(payload))
                #self.send ( self.buffer , self.length , 40 )
                self.prev_irq = 0
                self.length = 0
                for x in range(len(self.buffer)):
                    self.buffer[x] = 0

    def send(self, packet, length = None , mul = 40):
        try:
            length = length or len(packet)
            self.recv.irq(trigger = 0 , handler = None) # Disable IRQ Receiving Channel
            sleep = sleep_us
            duty = self.pwm.duty
            n = 0 # prev
            b = ticks_diff
            c = ticks_us
            for x in range(length):
                if x%2 == 0 :
                    duty(512)
                else :
                    duty(0)
                sleep( packet[x])
            duty(0)
            sleep_ms(3) # magic
            self.recv.irq(trigger = Pin.IRQ_RISING|Pin.IRQ_FALLING , handler = self._handler) # Re-enable IRQ
        except Exception as e:
            print('Error occurred : ' + repr(e))

Mqtt回调函数：（在Remote类之外）

def sub_cb(topic, msg):
    try:
        global remote
        data = json.loads(msg)
        remote.send(data['buffer'], data['length'], 40)
    except Exception as e:
        print('Error occurred : ' + repr(e))

启动了一个新线程，以便mqtt可以在红外接收器等待信号的同时从服务器检查发布的方法。

def main():
    global remote
    s = startup()
    client.set_callback(sub_cb)
    client.connect()
    client.subscribe(b"remote/receive/12345")
    _thread.start_new_thread(mqtt_thread, ())
    remote._routine()

remote.send(data['buffer'], data['length'], 40)仍然会传输信号，但是我希望在给定相同参数的情况下，它会以与self.send ( self.buffer , self.length , 40 )相同的方式工作。我使用另一个ESP32记录了两个信号，但找不到两者之间的差异。

任何帮助将不胜感激！

从Remote类的内部/外部调用send函数有什么区别？
