Device Control apps for Android

We have developed an electronic circuit for Android based interface will be designed in two separate TCP control . The project is based on a simple basis , operate relay control . In practice, we want to have features: * Application TCP communication application. * App password entry screen will appear at the opening . This display the IP , port, and you want to enter a password can access the device . If the user device settings ( IP, port, password , device output type, output names) have been previously saved , the " Power On " button that can be called by clicking the settings . In this case the IP , port, and password settings for the automatic entry will be read from . * Connection request is successful ( not the correct password and user limit ), the device consists of 2 bytes together with knowledge of results was answered to send a Session ID . Otherwise it sends an error code . * Session ID , device or communication in sending each command is provided in the connection security . After the connection is successfully made * Output Type from the device (relay , etc. ) information to be requested . Output Type information consists of 6 different definition : " ON-OFF ", " PWM ", " PPM" , " IDLE ", " PASSIVE ", "ERROR " . Of these "passive " and "fault" other than the identification of the active Output Type that will appear on the screen , respectively. * According to the Interface Output Type 3 different control methods to be found. These include: ON-OFF = On-off switch , setting the PWM = 0-100% , PPM = balance setting ( + 100% - 100%) forms to be found. * If the user wants each one to determine a name Output can give ( Output will be paired with ID ) . With the name that you want to save these settings . For example : 1 EV of devices Output = Bedrooms, 2 Output = as Hall ; WORK PLACE device for the output from the 1st Output = Office, 2 Output = Sektreterlik can be set . * Output control interface will be carried out , the feedback will be sent by the device . * Communication commands, XML , JSON, etc. . will be hosted in data structures , such as encrypted . Communication algorithm and command information , we will provide business with the adoption .
