Conectando a Helium

Helium console es una plataforma de gestión en la red Helium para registrar, configurar y enrutar datos de dispositivos LoRaWAN, permitiendo un despliegue rápido de IoT. Esta sección te enseñará cómo integrar rápidamente tu dispositivo en Helium.

Configuración del Dispositivo​

Antes de conectar a Helium, necesitas configurar los parámetros básicos de tu dispositivo en la APP SenseCraft, consulta Primeros Pasos para más detalles.

  • Establece la plataforma en Helium, y luego copia el Device EUI/App EUI/App Key.

Configuración de Helium Console​

nota

La consola de Helium ya no está abierta para nuevas cuentas. La descripción de cómo conectar un T2000 a la Consola de Helium permanece aquí para usuarios que ya tienen una cuenta. Para nuevos usuarios, por favor consulta los pasos de ChirpStack LNS a continuación o determina los pasos necesarios para tu LNS particular basándote en los dos ejemplos existentes aquí.

Paso 1: Agregar Nuevo Dispositivo​

Inicia sesión en tu Helium console, luego ve a la sección Devices y haz clic en el botón Add device.

pir

Completa los campos requeridos como el nombre del dispositivo, las credenciales LoRaWAN, etc.
Luego haz clic en el botón Save Device.

Paso 2: Crear la Función Decodificadora​

El siguiente paso es configurar la función que decodificará los bytes sin procesar en una forma legible para humanos.
Ve a la pestaña Function en el panel del lado izquierdo. Luego haz clic en el botón Add New Function y dale un nombre:

Copia el siguiente código para completar el CUSTOM SCRIPT y luego guarda los cambios.

Paso 3: Verificar los Datos​

Cuando el dispositivo intenta conectarse a la red, la luz verde parpadeará de forma intermitente. Si el dispositivo se une a la red exitosamente, la luz verde parpadeará 5 veces rápidamente.

Luego puedes verificar los datos en la consola de Helium.

ChirpStack LNS​

Para nuevos usuarios, para recibir los datos de un dispositivo en la red Helium debe estar asociado con un LNS (Servidor de Red LoraWAN), típicamente se usa uno de los LNS públicos, muchos de los cuales usan ChirpStack, pero también es posible conectar el propio LNS a Helium.

Para aquellos familiarizados con el proceso general, el resumen es:

  • crear un perfil de dispositivo con la región apropiada y el códec (ver código fuente abajo)
  • crear dispositivo con devEUI, appKey, y una variable app_eui con el AppEUI, los tres valores provenientes de la App SenseCraft

Paso 1: Agregar Perfil de Dispositivo​

El primer paso es agregar un perfil de dispositivo para el T2000 Tracker a tu ChirpStack LNS. Esto le dice al LNS cómo decodificar los paquetes que recibe de un T2000 así como una serie de otras configuraciones.

En el panel de ChirpStack selecciona Device Profiles y haz clic en Add device profile.

image

En la pestaña general, ingresa un nombre de perfil de dispositivo que reconozcas y selecciona los parámetros de región apropiados.

note

Versión MAC de LoRaWAN: 1.0.4

El intervalo de uplink esperado también se puede configurar, lo principal que controla es cuándo la interfaz de usuario del LNS muestra el dispositivo como activo vs. inactivo. No tiene efecto en la entrega de paquetes a través del LNS.

Haz clic en Submit, luego puedes ver Device profile created.

Paso 2: Agregar Aplicación y Tu Dispositivo​

El siguiente paso es crear una aplicación y agregar dispositivos reales a ella.

Ve a la sección Applications y agrega una nueva aplicación.

pir

Luego agrega un dispositivo a la aplicación e ingresa el devEUI como se capturó en la App SenseCraft anteriormente.

pir

En la pestaña de variables agrega una variable llamada app_eui con el AppEUI de la app SenseCraft como valor:

Al hacer clic en enviar aparecerá una página solicitando el AppKey, nuevamente como se capturó anteriormente usando la app SenseCraft.

Paso 3: Ver la Conexión del Dispositivo​

En la pestaña LoRaWAN frames verás un indicador de carga y luego aparecerán paquetes a medida que se reciben/envían.

Cuando veas JoinAccept y JoinRequest, indica que el T2000 se ha unido exitosamente a la red.

image

Una vez que se ha realizado el proceso de unión, el T1000 envía datos. El LNS responde con información sobre las frecuencias de red y demás, pero después de eso solo debería haber enlaces ascendentes con datos.

En la página Events, puedes ver los datos decodificados del dispositivo.
