Hola bentele,
necesitamos más información:
- Módulo que estás utilizando y sobre que plataforma.
- Fotos de tu configuración Hardware.
- Código completo.
- Detallada descripción del fallo.
Un saludo.
Hola, la placa es arduino UNO R3 y el shield es el SIM5218E. Acá les adjunto el código completo, con excepción del nombre y clave del servidor (por cuestiones de seguridad). El código no es eficiente, es decir, a la hora de ejecutar el programa, descarga y carga el archivo al servidor correctamente (no en todos los casos) pero en el programa de arroja carga fallida, como que la respuesta de los comando AT no fueran los correctos. Algunas veces sube el archivo incompleto. como podría solucionar esto?. también me gustaría saber como guardo esos archivos de descargo en la SD que le coloqué al shield. Atento a su respuesta y muchas gracias de antemano. Trabajando directamente en el IDE arduino 1.6.6
