Požadavky​

Nahrání firmwaru​

V tomto postupu použijeme HARDWARIO Playground k nahrání firmwaru do Core Module.

Krok 1: Připojte Micro USB kabel k Core Module a počítači​

Krok 2: Nahrajte firmware​

Spusťte HARDWARIO Playground. Na záložce Firmware vyberte a nahrajte firmware bcf-radio-power-controller do Core Module:

Pokud používáte LED pásek s 144 RGBW LED diodami:

bcf-radio-power-controller-rgbw144

Pokud váš LED pásek má 150 RGB LED diod:

bcf-radio-power-controller-rgb150

Pokud váš LED pásek má 72 RGBW LED diod:

bcf-radio-power-controller-rgbw72
warning

Nahrávání firmwaru pro Core Module R1 & R2 Pro rozdíly mezi starší verzí Core Module 1 a novější verzí Core Module 2 si prosím přečtěte dokument Porovnání Core Module R1 a R2 v sekci Hardware.

Krok 3: Odpojte kabel Micro USB od Core Module a vašeho počítače.​

success

V tomto bodě byl firmware úspěšně nahrán.

Sestavení hardwaru​

Podívejte se na krátké video s jednoduchou ukázkou krok za krokem:

Krok 1: Začněte s Power Modulem.​

warning

Ujistěte se, že do Power Modulu není připojen napájecí adaptér.

Krok 2: Připojte Core Module na Power Module​

Krok 3: Připojte Cover Module na Core Module​

Krok 4: Vložte sestavené moduly do krabičky BCE301 a zajistěte je pomocí O-kroužků​

Sestavené moduly Power Controlleru v červené krabičce BCE301, otevřená i zavřená varianta s konektory na boku

Krok 5: Připojte LED pásek do šroubovací svorky na pravé straně​

Krok 6: Připojte 5V DC napájecí adaptér​

Spuštění v Playgroundu​

danger

Pokud používáte nový HARDWARIO Playground, pak místo adresy http://localhost:1880/ použijte záložku Functions. Proces párování nyní probíhá v záložce Devices. Pro testování komunikace použijte záložku Messages.

Krok 1: Otevřete Node-RED ve svém webovém prohlížeči​

http://localhost:1880/

Krok 2: Měli byste vidět prázdnou pracovní plochu s názvem Flow 1​

Krok 3: Vložení snippetu do toku (přes Menu >> Import >> Clipboard) a klikněte na záložku Flow 1, poté klikněte na Deploy pro nasazení toku.​

Bude to vypadat takto:

info

Tento útržek poskytuje ovládací tlačítka pro příkazy bráně/rádiu. Tyto příkazy jsou odesílány prostřednictvím protokolu MQTT.

Krok 4: Nasazení flow pomocí tlačítka Deploy v pravém horním rohu​

Krok 5: Otevřete kartu debug​

Editor Node-RED se zvýrazněnou záložkou debug v pravém panelu

info

Na kartě debug budete moci vidět všechny MQTT zprávy.

Krok 6: Klikněte na tlačítko List all gateways. V záložce debug byste měli vidět odpověď podobnou této.​

Záložka debug s odpovědí brány obsahující název firmwaru a ID po kliknutí na List all gateways

success

V tomto bodě máte funkční Node-RED, MQTT, HARDWARIO Radio Dongle a HARDWARIO Gateway.

Párování​

V této části vytvoříme rádiové spojení mezi Radio Dongle a Radio Smart LED páskem.

Postupujte podle těchto kroků v Node-RED:

Krok 1: Klikněte na tlačítko Start node pairing​

Flow v Node-RED se zvýrazněným inject tlačítkem Start node pairing

Krok 2: Připojte napájecí adaptér do Sady Control, čímž odešlete požadavek na spárování (měli byste také vidět, že červená LED na Core Modulu svítí přibližně 2 sekundy)​

Krok 3: Klikněte na tlačítko Stop node pairing​

Flow v Node-RED se zvýrazněným inject tlačítkem Stop node pairing

success

V tomto bodě jste navázali bezdrátové spojení mezi (Radio Smart LED Strip) a bránou (Radio Dongle).

Test komunikace​

Postupujte podle těchto kroků v Node-RED:

Krok 1: Přepněte se na kartu debug vpravo​

Krok 2: Vložte následující úryvek do flow (pomocí Menu >> Import) a klikněte na záložku Flow 1​
