Upload image

Here is an example of uploading photos taken with the camera to the FlashAir IoT Hub.

Please prepare to be able to connect from FlashAir to FlashAir IoT Hub in advance referring to Flow of use.

CONFIG file change

Edit the FlashAir CONFIG file. Please set the following value in /SD_WLAN/CONFIG.

LUA_SD_EVENT=/upload_image.lua

I have specified that Lua script to upload images be executed when writing files.

* If you do not upload images, please comment out LUA_RUN_SCRIPT in the CONFIG file. When Lua script specified by LUA_RUN_SCRIPT and LUA_SD_EVENT are executed at the same time, it may not work well.

When you insert FlashAir in the camera, it is ready. With this alone you can upload photos from the camera automatically!

Upload photos

Let's take a picture with a camera that actually inserted FlashAir and see the "file" of FlashAir IoT Hub.
* When shooting please go in a place where FlashAir can connect to the access point.

Photographs taken were uploaded to FlashAir IoT Hub automatically.

In this tutorial, I upload only newly shot pictures, but please upload all saved pictures to FlashAir and try to change them by devising them yourself.

Upload non-image

Here is an example of uploading the video taken with the camera to FlashAir IoT Hub.

In the above I uploaded images, I think that sometimes I want to upload a video from a camera other than photos.

In such a case, let's upload the file from FlashAir in the following way.

CONFIG file change

Edit the FlashAir CONFIG file. Please set the following value in /SD_WLAN/CONFIG.

LUA_SD_EVENT=/upload_file.lua

I have specified that a Lua script to upload files should be executed when writing files.

* If you do not upload images, please comment out LUA_RUN_SCRIPT in the CONFIG file. When Lua script specified by LUA_RUN_SCRIPT and LUA_SD_EVENT are executed at the same time, it may not work well.

Finally, FlashAir is ready to insert in the camera.

Upload video

Take a movie with the camera that inserted FlashAir and take a look at the "file" of FlashAir IoT Hub.
* When shooting please go in a place where FlashAir can connect to the access point.
* It may take time to upload videos.

Video uploaded! Please download and play the uploaded file.

Change folder to be uploaded

In the example above, I uploaded an example of uploading movie files, but I think that you may want to upload a file of sensor data written in FlashAir as it is.

upload_file.lua uploads the latest file under the /DCIM folder, but if you want to change this to an arbitrary folder, edit it as follows.

upload_file.lua

print("HTTP/1.1 200 Internal OK\n\n")
local last_fname = ""
local last_fpath = ""
local last_modif = 0
local last_moddir = 0
local last_dirname = "/DCIM"
local fpath = "/DCIM"
(snip)

• Lines 6-7:
  Change the values of the variables last_dirname, fpath to the folder path where the file you want to upload is written.

This will be able to automatically send sensor data from FlashAir.

Send a CSV file to the FlashAir IoT Hub and display it on a graph, or send the GPIO value etc. , We offer various ways to send data, so why not try it?
