Remote control GPO, buzzer and speaker

Introduction

Controlling the GPO lines, speaker and buzzer is done by issuing HTTP GET requests.

All HTTP GET requests follow the same base structure.

HTTP GET ${device-ip}:3161/devices/${device-id}/${parameters}

Where:

• • ${device-ip}: device IP address

  • ${device-id}: device ID address

  • ${parameters}: are specific to the command

Device ID

The device ID can be easily discovered accessing the follwoing URL from any web browser

http://${device-ip}:3161/devices

GPO lines control

Enable/Disable

The particular HTTP GET request is

HTTP GET ${device-ip}:3161/devices/${device-id}/setGPO/${line}/${value}

Where:

• • ${line}: is the GPO line number: 1, 2, 3, 4, 5

  • ${value}

    • true: for high value

    • false: for low value

Examples

To enable and disable line 1

http://192.168.1.112:3161/devices/AdvanReader-m2-60/setGPO/1/true

http://192.168.1.112:3161/devices/AdvanReader-m2-60/setGPO/1/false

GPO operation

A GPO operation allow to execute a compound GPO action: enable/disable a certain GPO line for a certain duration

The particular HTTP GET request is

HTTP GET ${device-ip}:3161/devices/${device-id}/GPOOperation/${line}/${value}/${time-on}/${time-off}/${time-total}

Where:

• • ${line}: is the GPO line number: 1, 2, 3, 4, 5

  • ${value}

    • true: for high value. In this case it means we do not negate the output

    • false: for low value. In this case it means we negate the output

  • ${time-on}: is the active time of the GPO operation in ms

  • ${time-off}: is the quiet time of the GPO operation in ms

  • ${time-total}: is the total time of the GPO operation action in ms

Examples

To create a flashing effect on line 1

http://192.168.1.112:3161/devices/AdvanReader-m2-60/GPOOperation/1/true/150/150/900

Buzzer control

The particular HTTP GET request is

HTTP GET ${device-ip}:3161/devices/${device-id}/buzzer/${time-on}/${time-off}/${time-total}

Where:

• • ${time-on}: is the active time of the buzzer in ms

  • ${time-off}: is the quiet time of the buzzer in ms

  • ${time-total}: is the total time of the buzzer action in ms

Valid values can be seen at

Examples

http://192.168.1.112:3161/devices/AdvanReader-m2-60/buzzer/200/200/600

Speaker control

The particular HTTP GET request is

HTTP GET ${device-ip}:3161/devices/${device-id}/speaker/${freq}/${volume}/${time-on}/${time-off}/${time-total}

Where:

• • ${freq}: tone frequency. Possible values: 1000,1500,2000,2500,3000,3500,4000,4500,5000

  • ${volume}: volume: Possible values: from 1 to 10.

  • ${time-on}: is the active time of the buzzer in ms

  • ${time-off}: is the quiet time of the buzzer in ms

  • ${time-total}: is the total time of the buzzer action in ms

Valid values can be seen at

http://${device-id}:3161/devices/${device-id}/MCU/features/

Examples

Two tones at 3000 Hz and low volume
