Conectando SenseCAP T1000 a Helium
Configuración del Dispositivo
Antes de conectar a Helium, necesitas configurar los parámetros básicos de tu dispositivo en la APP SenseCAP Mate, consulta Primeros Pasos para más detalles.
- Establece la plataforma a
Helium, y luego copia elDevice EUI/APP EUI/APP Key.
Configuración de la Consola Helium
La consola de Helium ya no está abierta para nuevas cuentas. La descripción de cómo conectar un T1000 a la Consola Helium permanece aquí para usuarios que ya tienen una cuenta. Para nuevos usuarios, por favor consulta los pasos de ChirpStack LNA arriba o determina los pasos necesarios para tu LNA particular basándote en los dos ejemplos existentes aquí.
Agregar Nuevo Dispositivo
Inicia sesión en tu consola Helium, luego ve a la sección Devices y haz clic en el botón Add device.
Completa los campos requeridos como el nombre del dispositivo**,** las credenciales LoRaWAN, etc.
Luego haz clic en el botón Save Device.
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 y luego guarda los cambios.

Verificar los datos
Cuando el dispositivo intenta conectarse a la red, la luz de respiración parpadeará. Si el dispositivo se une a la red exitosamente, la luz de respiración parpadeará rápidamente, y habrá una melodía ligera y alegre.
Luego puedes verificar los datos en la consola de Helium.
Nota
note
Para usuarios que operan con la región EU868/RU864:
No se recomienda establecer el intervalo de carga a menos de 4 minutos.
Si estableces un intervalo de carga de menos de 4 minutos, puedes notar una desalineación de marca de tiempo entre el uplink del dispositivo y la hora actual.
Aquí está la justificación:
Dada la restricción del ciclo de trabajo del 1% en EU868, el dispositivo debe esperar pacientemente aproximadamente 4 minutos para cada transmisión de uplink. Además, la red Helium inicia correcciones de velocidad de datos y potencia solo después de acumular 20 paquetes de uplink consecutivos marcados con el bit ADR establecido en 1.
Así que si el intervalo de carga que estableces es menor a 4 minutos, los datos en tiempo real se almacenarán temporalmente en RAM y se mantendrán hasta que la red Helium active las correcciones de velocidad de datos y potencia antes de cargar.
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 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 TL;DR; es:
- crear un perfil de dispositivo con la región apropiada y el codec (ver fuente abajo)
- crear dispositivo con
devEUI,appKey, y una variableapp_euicon el AppEUI, los tres valores provenientes de la AppSenseCraft
Añadir perfil de dispositivo
El primer paso es añadir un perfil de dispositivo para el T1000 Tracker a tu ChirpStack LNS. Esto le dice al LNS cómo decodificar los paquetes que recibe de un T1000 así como una serie de otras configuraciones.
En el panel de ChirpStack selecciona los Device Profiles y haz clic en Add device profile.
En la pestaña general, ingresa un nombre de perfil de dispositivo que reconozcas y selecciona los parámetros de región apropiados.
Versión MAC de LoRaWAN: 1.0.4
El intervalo de uplink esperado también se puede establecer, 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.
En la pestaña Codec selecciona JavaScript functions e ingresa el codec:
tip
Hay 2 versiones de ChirpStack, selecciona la apropiada:
Añadir Aplicación y tu Dispositivo
El siguiente paso es crear una aplicación y añadir dispositivos reales a ella.
Ve a la sección Applications y añade una nueva aplicación.
Luego añade un dispositivo a la aplicación e ingresa el devEUI como se capturó en la App SenseCraft anteriormente.
En la pestaña variables añade una variable llamada app_eui con el AppEUI de la app SenseCraft como valor:
Presionar enviar mostrará una página pidiendo la AppKey, nuevamente como se capturó anteriormente usando la app SenseCraft:
Ver la conexión del dispositivo
En la pestaña LoRaWAN frames verás un spinner y luego aparecerán paquetes conforme se reciban/envíen.
Presiona el botón de tu T1000 Tracker para hacer que tome una medición y envíe una join request para conectarse con el LNS.
Una vez que esto suceda, deberías ver algo como esto:
Una vez que el proceso de unión se ha realizado, el T1000 envía datos. El LNS responde con alguna información sobre las frecuencias de red y demás, pero posterior a eso solo debería haber uplinks con datos.
