    BLE Conexion




      I am doing a project to show me on an LCD screen (I2C) the data that the DHT22 sensor collects.

      The error I think is at the time of the notification, with the cypress APP when clicking on Notify does not change anything and doesn´t it show me the data.

      I attached the programm.

      I hope your answers. Thanks greetings.

          In the project, you are trying to send the float values through the notification. But CyBle_GattsNotificationcan() accept only arrays of uint8 type. A float value may be represented in 4 bytes and you can send the Float value as an uint8 array with 4 elements.

          Please let me know if this helps.
