Top Forums Programming Wuhan Coronavirus Status for China - Rapid Prototype Blynk App with ESP8266 Post 303043594 by Neo on Saturday 1st of February 2020 12:07:24 PM

The mistake I made in this humanitarian crisis situation was to use Blynk to build a public service app to help others.

I will not make that mistake again.

In addition, I also read the Blynk privacy policy and according to their privacy policy, they can provide the data we use on the Blynk network to third parties, for example Google and FB-like behavioral analytics, where they can partner with data miners and other third parties and user our "behavioral exhaust" without our express written consent.

From Blynk Terms of Use (TOS) policy:

Quote:
By using the [Blynk] Service, you are granting us (and any service providers or Providers used by us) permission to access your account and those messages, data, information, text, graphics, audio, video or other material and content of any kind posted/uploaded/transmitted to or through the Service using your account, to process and submit said material to End Users.
That is a very "radical" TOS statement, to say the least.......

Update:

After looking into this, I found some promising iPhone apps which do not share your data with third parties (in contrast to Blynk) and will test the mosquitto broker to set up a private pub/sub network to send and receive messages to and from these ESP8266 and ESP32 devices.

Quote:
Eclipse Mosquitto is an open source (EPL/EDL licensed) message broker that implements the MQTT protocol versions 5.0, 3.1.1 and 3.1. Mosquitto is lightweight and is suitable for use on all devices from low power single board computers to full servers.

The MQTT protocol provides a lightweight method of carrying out messaging using a publish/subscribe model. This makes it suitable for Internet of Things messaging such as with low power sensors or mobile devices such as phones, embedded computers or microcontrollers.

The Mosquitto project also provides a C library for implementing MQTT clients, and the very popular mosquitto_pub and mosquitto_sub command line MQTT clients.
I have already set up a mosquitto broker on Ubuntu, the basic security authentication and can send a message from my ESP32 device to the remote Linux server. Will discuss this in another post.

Was not really happy with the NTP clients for the ESP8266 because, after a few years of game engine programming, I am not a fan of a lot of code and delays in the main loop, so here is a "slightly better NTP client" for the ESP8266. In a nutshell, instead of having a delay in the main loop as a... (1 Reply)

NAME
App::Cmd::Setup - helper for setting up App::Cmd classes VERSION
version 0.318 OVERVIEW
App::Cmd::Setup is a helper library, used to set up base classes that will be used as part of an App::Cmd program. For the most part you should refer to the tutorial for how you should use this library. This class is useful in three scenarios: when writing your App::Cmd subclass Instead of writing: package MyApp; use base 'App::Cmd'; ...you can write: package MyApp; use App::Cmd::Setup -app; The benefits of doing this are mostly minor, and relate to sanity-checking your class. The significant benefit is that this form allows you to specify plugins, as in: package MyApp; use App::Cmd::Setup -app => { plugins => [ 'Prompt' ] }; Plugins are described in App::Cmd::Tutorial and App::Cmd::Plugin. when writing abstract base classes for commands That is: when you write a subclass of App::Cmd::Command that is intended for other commands to use as their base class, you should use App::Cmd::Setup. For example, if you want all the commands in MyApp to inherit from MyApp::Command, you may want to write that package like this: package MyApp::Command; use App::Cmd::Setup -command; Do not confuse this with the way you will write specific commands: package MyApp::Command::mycmd; use MyApp -command; Again, this form mostly performs some validation and setup behind the scenes for you. You can use "base" if you prefer. when writing App::Cmd plugins App::Cmd::Plugin is a mechanism that allows an App::Cmd class to inject code into all its command classes, providing them with utility routines. To write a plugin, you must use App::Cmd::Setup. As seen above, you must also use App::Cmd::Setup to set up your App::Cmd subclass if you wish to consume plugins. For more information on writing plugins, see App::Cmd::Manual and App::Cmd::Plugin. AUTHOR
