各位大佬好,我这边使用arduino mega2560+SIM7020C,想接入点灯科技,这边使用了网站里的例程代码
  1. #define BLINKER_NBIOT_SIM7020

  2. #include <Blinker.h>

  3. char auth[] = "007093b088f6";

  4. // 新建组件对象
  5. BlinkerButton Button1("btn-abc");
  6. BlinkerNumber Number1("num-abc");

  7. int counter = 0;

  8. // 按下按键即会执行该函数
  9. void button1_callback(const String & state) {
  10.     BLINKER_LOG("get button state: ", state);
  11.     digitalWrite(LED_BUILTIN, !digitalRead(LED_BUILTIN));
  12. }

  13. // 如果未绑定的组件被触发,则会执行其中内容
  14. void dataRead(const String & data)
  15. {
  16.     BLINKER_LOG("Blinker readString: ", data);
  17.     counter++;
  18.     Number1.print(counter);
  19. }

  20. void setup() {
  21.     // 初始化串口
  22.     Serial.begin(115200);
  23.     BLINKER_DEBUG.stream(Serial);
  24.    
  25.     // 初始化有LED的IO
  26.     pinMode(LED_BUILTIN, OUTPUT);
  27.     digitalWrite(LED_BUILTIN, HIGH);
  28.     // 初始化blinker
  29.     Blinker.begin(auth, 50, 51, 9600);
  30.     Blinker.attachData(dataRead);
  31.     Button1.attach(button1_callback);
  32. }

  33. void loop() {
  34.     Blinker.run();
  35. }
复制代码

始终没法成功连接MQTT,请问我应该怎么解决这个问题啊,NB-IoT模块已经按照厂商给的文档测试过没啥问题啊

不排除是SIM模块固件变更引起的,我们会在近期重新测试该模块可用性

SIM7020C C是国内版,这个版本淘宝的固件在MQTT方面就是个天坑,
首先是不支持用网址链接MQTT服务器,只支持IP链接(更新微雪提供的新固件可以解决),
其次就是MQTT clientid name pwd太长直接ERROR了,
再然后就是模块发送接收的数据都只能用16进制字符串(修改后压根不生效)
