ESP32+SIM800L实现MQTT功能 断断续续搞了好一阵子终于可以在SIM800L上跑MQTT了。SIM800L本身是不支持MQTT的,但是模块本身很小巧很便宜,也很稳定。我就不喜欢什么功能都封装成AT指令,明明这些可以自己用软件来实现的,平白无故还增加了成本。说说具体做法,其实在ESP32上已经很容易做到了,IDF本身有MQTT协议栈(基于lw...
思路同上一篇:本例程实现了以下功能:通过SIM800L连接网络连接OneNet平台(通过新版MQTTs协议)调用SHT20的库采集温湿度将温湿度信息上传至OneNet每5分钟采集一次, 采集完成就休眠#include <Arduino.h>#include "PubSubClient.h"#include "Ticker.h"#include "uFire_SH..
I've also experimented with the TinyGSM and the Hologram SIMCOM libraries as well just trying to get a connection or the board to recognize the SIM800L. I have both Hologram and Ting to test with but can't get either one working. It would be great to figure out how to get this wo...
Hello, Please, is there any library with examples of using SIM800l module with ESP32 (ESP-IDF) to send/receive SMS ? *I tried the official PPP example, but it didn't work! Thank you.1 post • Page 1 of 1 Return to “General Discussion” Jump to Who is online Users browsing ...

The first sketch sends GPS Data to Blynk using SIM800L. (Using ESP32 TTGO board) The second sketch sends GPS data to Thingspeak via Wifi. (Using ESP8266) So I combined the two sketches with a bit of editing to achieve what i want. However, the code is...
