NB-IoT接入问题

zj3131031

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. 
   
3. #include <Blinker.h>
   
4. 
   
5. char auth[] = "007093b088f6";
   
6. 
   
7. // 新建组件对象
   
8. BlinkerButton Button1("btn-abc");
   
9. BlinkerNumber Number1("num-abc");
   
10. 
    
11. int counter = 0;
    
12. 
    
13. // 按下按键即会执行该函数
    
14. void button1_callback(const String & state) {
    
15.     BLINKER_LOG("get button state: ", state);
    
16.     digitalWrite(LED_BUILTIN, !digitalRead(LED_BUILTIN));
    
17. }
    
18. 
    
19. // 如果未绑定的组件被触发，则会执行其中内容
    
20. void dataRead(const String & data)
    
21. {
    
22.     BLINKER_LOG("Blinker readString: ", data);
    
23.     counter++;
    
24.     Number1.print(counter);
    
25. }
    
26. 
    
27. void setup() {
    
28.     // 初始化串口
    
29.     Serial.begin(115200);
    
30.     BLINKER_DEBUG.stream(Serial);
    
31.    
    
32.     // 初始化有LED的IO
    
33.     pinMode(LED_BUILTIN, OUTPUT);
    
34.     digitalWrite(LED_BUILTIN, HIGH);
    
35.     // 初始化blinker
    
36.     Blinker.begin(auth, 50, 51, 9600);
    
37.     Blinker.attachData(dataRead);
    
38.     Button1.attach(button1_callback);
    
39. }
    
40. 
    
41. void loop() {
    
42.     Blinker.run();
    
43. }

但是串口监视器中显示

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）
