Electronic, 3D printing and embedded programming
For static information (Web pages for examples), that not change frequently, esp8266 or esp32 have internal SPIFFS (SPI Flash File System) and you can upload data via Arduino IDE as explained in the article “WeMos D1 mini (esp8266), integrated SPIFFS Filesystem” but for fast operation and future support It’s usefully use FTP.
When you create a datalogging It’s important to structure your data, sometime a good solution can be JSON format.
Here a tutorial on E32 LoRa (Long Range) device very cheap and very long range (from 3Km to 8Km).
In this chapter we are going to wake on radio the LoRa E32 and microcontroller and we show the shield created for this device.
When you use a microcontroller an important features is store data, for logging or setting, for a web server or to show image. The better solution is an SD card, because It’s simple, small and low power device.
Now we are going to look how to connect and use with standard SD library with Arduino and esp8266.
Here a tutorial on E32 LoRa (Long Range) device very cheap and very long range (from 3Km to 8Km).
In the last chapter we are going to send complex structure.
When you create a new IoT project probably you need to connect microcontroller to a battary power source, but if you don’t use a power saving options your battery will run out in no time.
As a lot of IoT microcontroller, WeMos D1 mini have some power saving mode.
The types are modem sleep, light sleep and deep sleep.
Here is a tutorial on the E32 LoRa (Long Range) device’s very cheap and long-range (from 3Km to 8Km).
Now we are going to understand the various transmission type
Here is a tutorial on the E32 LoRa (Long Range) device’s very cheap and long-range (from 3Km to 8Km).
It’s time to understand the configuration.
Here a tutorial on E32 LoRa (Long Range) device very cheap and very long range (from 3Km to 8Km).
Here my library to simplify the complex usage.
Here a tutorial on E32 LoRa (Long Range) device very cheap and very long range (from 3Km to 8Km).
Start with specs and basic usage.
