    Sì, puoi fare così

    Il nodo sul tetto sarà un dispositivo autonomo, con un suo ID.

    Non ha bisogno del Bluetooth una volta configurato.
    Il Bluetooth serve solo per la configurazione iniziale.

    Procedura corretta:

    1️⃣ Lo configuri da vicino con il telefono (Bluetooth).
    2️⃣ Imposti modalità (client o router), parametri, canale ecc.
    3️⃣ Lo installi sul tetto.
    4️⃣ Da quel momento lavora da solo.

    I messaggi del tuo nodo “mobile” arriveranno al tetto via radio, non via Bluetooth.

    Il Bluetooth non c’entra nulla con il funzionamento mesh, serve solo per configurare.

    Puoi usare la stessa app per configurare entrambi i nodi, uno alla volta.
    Non devono “ricevere solo da uno”: nella mesh parlano con chiunque sia sulla stessa frequenza e con gli stessi parametri.

    In pratica:

    📡 Nodo mobile → parla via LoRa
    📡 Nodo sul tetto → inoltra ciò che riceve via LoRa
    📱 Bluetooth → solo per configurazione locale

    Una volta sul tetto, il nodo è indipendente.

  • @ilarioq quando avvii l'app puoi selezionare il dispositivo dall'elenco, quindi si, chiaramente devi essere a "portata di bluetooth". Comunque con le ultime versioni oltre a configurarlo puoi anche aggiornare il nodo dallo smartphone senza smontarlo ogni volta dal tetto per collegarlo al PC @snow @lgsp @andre123 @gecco

    Capisco cosa intendi.

    Collegare il nodo a Internet con MQTT non crea copertura radio in quella zona.

    Crea un collegamento logico tra reti.

    Se nel punto dove lo metti non arriva alcun segnale LoRa, quel nodo:

    * non ripete nulla via radio
    * non estende copertura RF
    * non “illumina” la zona

    Fa solo da ponte tra radio locale (se presente) e rete Internet.

    Se domani in quella zona comparisse almeno un altro nodo LoRa, allora sì:
    potrebbe fare da ponte tra quel nodo e il resto della rete tramite MQTT.

    Ma finché non riceve nessuno via radio, resta un nodo isolato collegato a Internet.

    La copertura radio nasce solo da:

    * linea di vista
    * altezza
    * antenna
    * presenza di altri nodi raggiungibili

    Internet non sostituisce la propagazione RF.

    Se vuoi metterlo lì in attesa che compaiano altri nodi, va benissimo.
    Ma è un nodo in stand-by, non un estensore di copertura.

  • I have a question about Python libraries and testing scope.

    If I'm importing 'serial' in my library, and use it like the following to create a connection to a sensor:

    --- start code ---

    import serial

    class Sensor:
    def __init__(self, serial_device):

    self.__serial_device = serial_device

    try:
    self.__connection = serial.Serial(
    port=serial_device,
    baudrate=9600,
    bytesize=serial.EIGHTBITS,
    parity=serial.PARITY_NONE,
    stopbits=serial.STOPBITS_ONE,
    )

    except serial.SerialException:
    print("Could not establish serial connection to sensor")

    --- end code ---

    how much testing should I do around the serial connection? Just mock up a few buffers (byte streams), and see how my class handles unexpected input?

    One the one hand, I want to make the library as solid as possible. On the other hand, I don't want to run tests on code I don't control (the library module). I know of the 'mock-serial' utility, but haven't used it.

    The aim is to make a Python version of my Arduino library for the CozIR Ambient CO2 sensor:

    Just the other day I was thinking how much the presence of POC are missed on this platform. And then I scroll the comments of a post talking about systemic oppression and I'm reminded why #Mastodon is 99% white. How is it that so many of you are expert coders but haven't read a single book by an activist? How is it that you haven't accidentally come across even a quote to spark curiosity?This is especially concerning for Americans. We're facing fascism and still at "I don't see color"

    I think I have identified a fairly significant flaw in how the #Fediverse currently operates. Hear me out.The Fediverse currently consists of all sorts of different systems - #Mastodon, #Friendica , #Pixelfed , #PeerTube, #BookWyrm , and so forth. And while they are all connected via the #ActivityPub protocol, they all have different functionalities and different ways of presenting themselves. Which is as it should be, because Diversity Is Our Strength(TM).However, it is here that the ActivityPub-based interactivity hits its limits - for usually, you can either experience the relevant system as it was intended, or you can interact with it, but not both - _unless_ you have an account on the same system (though not necessarily on the same instance).Let's say that you are a Mastodon user who looks at another person's BookWyrm page. You scroll through their books, posts, and comments. Then you see some comment you want to comment on yourself, but can you do so?Not directly. You need to figure out the URL of their comment, and then copy and paste that comment into the search bar of your Mastodon instance. Then it will show up in the same format as a Mastodon post, and you can interact with it - boost it, like it, comment on it.Sure, it works, but it's a whole lot of tedious effort.Or you can search for the user account in Mastodon and scroll through all their posts and comments as if they were a Mastodon user - and thus, you will miss out on all the unique user interface features of BookWyrm.So what is missing?Well, Mastodon already has an "Open original page" feature when looking at someone's post. What we need is an "Open original page AND AUTHENTICATE" feature. This way, the target instance (whatever software they are using) could acknowledge the viewer as an external user who could nevertheless fully interact with the local user interface, including the ability to boost, like, and make comments.This is something that should be theoretically possible to implement, right? #FediHelp

    I have a confession. I installed my Mastodon server software on my VPS that is marketed as a "storage" VPS. 😎 How awesome is that? 😎 It has a 1TB SSD anyway and 18GB of RAM, so why not increase the RAM usage? 😎 #mastodon #fediverse #selfhosting #vps #storageserver #tech #geek #itstudent #humane_tech #decentralisation #openweb #technology #sysadmin #bigstorage #ram #ssd #doityourself #coding #linux #serverlife #webhosting #diytech #compute #network #activitypub #awesome #engineering
