Sensor commands plus a sample run of Softata Console App with Sensor selection.

c# Console Softatalib App commands for Sensors

App Start

SoftataLib.Init(ipaddressStr, port);
string SoftataLib.SendMessageCmd("Version"); //Get Arduino app Version
string SoftataLib.SendMessageCmd("Devices"); // Get list of device types supported

Sensor Queries and Setup

string[] SoftataLib.Sensor.GetSensors()
(byte)sensorLinkedListIndex = SoftataLib.Sensor.SetupDefault(sensorIndex)

Read Sensors

double[]? SoftataLib.Sensor.ReadAll(sensorLinkedListIndex,debug)
string SoftataLib.Sensor.GetTelemetry(sensorLinkedListIndex,debug)
double? SoftataLib.Sensor.Read(sensorLinkedListIndex, p,debug)
  • debug If false (default is true) can turn off some debug messages.

Sending Telemetry

To Bluetooth … to Azure IoT Hub coming

string SoftataLib.Sensor.SendTelemetry(sensorLinkedListIndex)
string SoftataLib.Sensor.PauseSendTelemetry(sensorLinkedListIndex)
string SoftataLib.Sensor.ContinueSendTelemetry(sensorLinkedListIndex);

Finish: Close app on Arduino device and restart it.

  • Executing soft reset of device puts it in a known (clear) state.

Corresponding Arduino commands

  • 0xF0: Sensor type commands
    • Param is the Sensor subcommand:
      • 0x00 GetPins
      • 0x01 GetProperties
      • 0x02 SetupDefault
      • 0x03 Setup
      • 0x04 ReadAll
      • 0x05 Read
      • 0x06 GetTelemetry
      • 0x07 SendTelemetryBT
      • 0x08 SendTelemetryToIoTHub (Coming)
      • 0x09 PauseSendTelemetry
      • 0x0A ContinueTelemetry
      • 0xFF GetSensors
  • Subcommands 0x00 to 0x03:
    other parameter specifies the sensor type
  • Subcommands 0x02 and 0x03:
    Both return the linked list node index where the reference to the instantiated sensor class instance is stored. Besides the pin parameter, the second (0x03) requires setup data specific to the sensor.
  • Subcommands 0x04 to 0x0A:
    other` parameter is that index to the sensor instantiated node in the sensors linked list

Note:_ Subcomands 0x00 to 0x03 are implemented specifically for each sensor type. Subcommands 0x04 to 0x0A are implemented in a sensor type agnostic manner, using class polymorphism. The last command requires no parameters.

Commands sent to Arduino server from Softatalib as array of bytes:

  • Length of array
  • Sensor Command Class Type (0xF0)
  • Pin
  • Param: Subcommand
  • Other: Sensor Type / Sensor Linked List index
  • OtherData:
    • Array of additional data (Used by 2nd Setup method)
    • Default setup uses default settings
