    We are working on a cost effective solution to extend the range of LORA for our application. We are trying to implement LORA in a mesh network, therefore, one node can send its signal to its neighbor nodes and after several attempts to the gateway. Actually, we want to put nodes every 500/1000 meters and have one gateway for each 10km*10km area. Do you think working on LORA to make it a mesh network makes sense or we should change the communication protocol? What would you do if you wanted to build such a system?

      I think LoRa is a good communication protocol for slow speeds. Mesh will reduce this speed and you have to decide if it is fast enough. Maybe a “relay” type of network is a better approach if you have a mountain close to your devices. Would be much easier and line of sight, LoRa works over many kilometers or miles. Most Amateur Radio concepts also depend on this kind of architecture.

    Hi Andreas,
    Great idea to open a blog!! I love your videos but I much appreciate the text interface (I guess it is also linked to my pre-web education). It is a very good complement to your YouTube channel even though I understand the tremendous quantity of work invested to reach this level of quality.

    I promise, from now on, I’ll always shop through the links on your page 😉

    I teach IoT development on various MPUs and MCUs, now I’m preparing a “Do your own sensor” unconference for absolute beginners and your shared experience with Wemos is very valuable. Hope I’ll have time to contribute on IoTAppStory.

    Cheers, Thierry

      Hi Thierry,
      I try to update documentation as soon as I have time.

    Hi Andreas,

    Would you be interested in doing a product review for us? We’ve built a USB charger that we’re launching on Kickstarter and we’d love for you to take a look. It’s pirlcharger.com and it’s unique because for the first time you don’t need a multimeter to know power draw – we’ve built in a wattmeter.

    Hello Andreas,
    i enjoy your videos but im not and never going to be a coder, but Node red has got me very interested.
    If possible are you able to produce some more videos dedicated towards node red and show how the dash is viewed on the iphone.
    i have a few projects in mind using ESP32 with rasp Pi
    Thanks for considering any future videos

    Kind regards

    Hello Andreas.

    I make a query not just about this particular blog but rather about a problem I have with the esp8266 modules and the possibility of controlling the exceptions. I am using a module and I need you to send some information once a day for 4 months and the rest of the time it must be in deepsleep.
    I found that from one day to another the battery was dead and when I could do a debug I found that it was in installation mode with which the battery was consumed quickly and the module was paused. Only a manual reset takes it out of that state.
    I wanted to ask you if you had a similar problem and if so you could solve it.
    Thank you very much.
    Your videos are very good, I like them a lot.

    Hi to all. Just to let you know that only a couple of days ago, version 2.4.2 for the ESP8266 core was announced on GitHub https://github.com/esp8266/Arduino/releases . Some Arduino IDE boards manager won’t find the update, since the url in the preferences file will still be looking for version 2.4.1…
    I tried to install version 2.4.2 manually, but it’s better to change the url in the Arduino IDE prefs to: https://github.com/esp8266/Arduino/releases/download/2.4.2/package_esp8266com_index.json, close the program, restart it, and then let the boards manager update automatically.

    Dear Andreas,

    Would you be interested in helping a dutch startup developing a cool (and relevant) new product? If yes please feel free to contact me for further details.

    Best regards,

      YouTube is my hobby and I do no consulting.

    Hello, Andreas.
    My name is Fernando Koyanagi. I’m from Brazil.
    I have a channel on Youtube, in Portuguese, in which I talk a lot about ESP32, IOT, electronics, among other subjects.
    I am an admirer of your work and follower of your channel, the quality of the projects and the creativity you have.

    I would like to propose a video in partnership with you.
    Are you interested?

    This is my channel: http://www.youtube.com/fernandokoyanagi
