NB-IoT接入问题
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#define BLINKER_NBIOT_SIM7020#include <Blinker.h>
char auth[] = "007093b088f6";
// 新建组件对象
BlinkerButton Button1("btn-abc");
BlinkerNumber Number1("num-abc");
int counter = 0;
// 按下按键即会执行该函数
void button1_callback(const String & state) {
BLINKER_LOG("get button state: ", state);
digitalWrite(LED_BUILTIN, !digitalRead(LED_BUILTIN));
}
// 如果未绑定的组件被触发，则会执行其中内容
void dataRead(const String & data)
{
BLINKER_LOG("Blinker readString: ", data);
counter++;
Number1.print(counter);
}
void setup() {
// 初始化串口
Serial.begin(115200);
BLINKER_DEBUG.stream(Serial);
// 初始化有LED的IO
pinMode(LED_BUILTIN, OUTPUT);
digitalWrite(LED_BUILTIN, HIGH);
// 初始化blinker
Blinker.begin(auth, 50, 51, 9600);
Blinker.attachData(dataRead);
Button1.attach(button1_callback);
}
void loop() {
Blinker.run();
}
但是串口监视器中显示17:46:03.264 ->

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 奈何col 发表于 2021-3-3 19:33
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）
