Intel® RFID Sensor Platform Frequently Asked Questions

What is the Intel® RFID Sensor Platform SW Toolkit?

The Intel® RFID Sensor Platform SW Toolkit (Intel® RSP SW Toolkit) is a set of software reference designs provided by Intel for use with the Intel® RFID Sensor Platform (Intel® RSP).

What are the minimum hardware requirements?

COMPONENT

DETAILS/NOTES

RFID Sensor(s)

H1000, H3000

Edge computer to run the Intel® RSP Controller application

CPU: Intel® Celeron® Processor or higher, 8MB Cache, RAM: 4 GB, SDD: 80 GB

Network Router

  • Manage internet connectivity (WAN)
  • Ability to provide dynamic IP addresses via DHCP to the sensors and edge computer.
  • Enables MDNS/Multicast/Cast Discovery

POE+ Switch or Injector

  • IEEE 802.3at
  • Make sure it can provide over 15 Watts of power for each connected sensor (H1000 and H3000 series).
    EXAMPLE: For 21 sensors, make sure the POE power supply provides at least 315 Watts of power (15 x 21 = 315)

RFID Tag(s)

  • EPC UHF RFID Class 1 Gen 2 (ISO 18000-6C)

Ethernet cables 

  • Cat. 5e, 6 or greater
  • Distance between a sensor and switch cannot be greater than 100m
  • Do not run cabling next to electrical cabling or fixtures as to avoid potential interference.
  • Avoid Ethernet cable couplers to extend the length of an existing cable.

OPTIONAL:  Android* device (phone or tablet)

  • Device running Android version 6 (Marshmallow) or greater with NFC write capabilities to support sensor provisioning.

Hardware Troubleshooting/Best Practices:

  • It's recommended to use smart, unmanaged POE+ switches that automatically detect required PoE power for the devices attached to the switch and protect the Non-PoE equipment from being damaged.
  • Also recommended are networking devices (routers, POE+ switches, etc) that can be remotely access or cloud supported. The ability to power-cycle a device at a remote location will be much more convenient rather than having to visit a site at a remote location.
  • Avoid wireless routers & switches. The system is not verified to operate in wireless networking environments.

How do I connect the hardware?

Your hardware should be connected and powered in the order shown below.  Make sure the Intel® RSP sensors are connected and powered after all the other hardware has powered up.   

Hardware Connection Troubleshooting/Best Practices:

Power up and allow your router and switch to fully boot up first.  The router will manage internet connectivity and provide dynamic IP addresses via DHCP to the sensors and edge computer.

Avoid daisy chain network topology using intermediate switches/routers.  

What are the Network Requirements?

The table below lists the outbound internet connections used by the system. These connections are established from the Intel® RSP Controller application and connect to systems on the internet. None of these connections are initiated from an external source.

Networking Troubleshooting/Best Practices:

  • Validate with your IT organization or networking resources that your outbound ports are not being blocked by firewalls or proxies.
  • It is recommended that you avoid or minimize the usage of other devices on the internal network that utilize auto discovery services (i.e. IP Cameras).

Why Doesn't the Sensor's LED Light Up?

Confirm your sensor is securely connected to a POE+(802.3at) switch or injector with an ethernet cable that is Cat5e or better, and the POE+ switch or injector can provide sufficient power for all the connected devices.

Why is my Sensor not Connecting to the Intel® RSP Controller Application?

Confirm your sensors and the edge computer running the Intel® RSP Controller application are connected on the same LAN (subnet) and disable any firewalls that could possibly restrict network connectivity.

How Can I Verify my Sensors are on the Same LAN (Subnet) as the Edge Computer Running the Intel® RSP Controller Application?

On the edge computer running the Intel® RSP Controller application, enter the following command in a Linux* terminal to display the sensors detected on that LAN (subnet).

intel@RSP:~$  avahi-browse -aptrv | awk '/=;/ && /IPv4/ && /RSP-/ && /SSH/' | sed 's/;/\t/g' | cut -f4,8 

RSP-150659 192.168.2.117

RSP-150994 192.168.2.109

Sensors will be displayed with "RSP-" and the last 6 characters of the sensors MAC. 

What do the Different Light Pattern on the Sensor’s LED Mean?

LED COLOR

LED PATTERN

SENSOR STATUS

ACTION REQUIRED

No Color (OFF)

An LED state of “off" indicates the Intel® RSP Sensor has either been commanded to disable its visual indicator or is otherwise non-operational.

  • Validate all hardware components are connected and powered as illustrated above.
  • Verify the sensor is securely connect to a POE+ switch.
  • Check to see if POE+ switch is powered on and the port on the switch is configured correctly.
  • Validate your POE+ switch meets minimum power requirements outlined in the hardware requirements.

Solid Green (Power On)

An LED state of "solid green" is the default to indicate power has been successfully applied to the Intel® RSP. This initial LED state should not last longer than 2 – 3 minutes. After 2 – 3 minutes, the LED color should transition to indicate successful OS boot.

No action required.
This state should not last longer than 2 or 3 minutes. If sensor does not transition:

  • Make sure the network router is powered and DHCP service is providing IP addresses. 
  • Unplug and re-plug the Ethernet cable to the sensor.

Light Blue

An LED state of “solid light blue" indicates the Intel® RSP Sensor has successfully booted to the Linux* OS, but the RFID application is not yet running.

No action required.
This state should not last longer than 2 or 3 minutes. If sensor does not transition:

  • Unplug and re-plug the Ethernet cable to the sensor.

Flashing White

Sensors are in the process of discovering the Inventory Management App.  

If blinking white for more than 5 minutes, than try the following:

  • Validate the edge computer and sensors are on the same network.
  • Disable firewalls.
  • Stop/Start the Intel® RSP Controller application
  • Unplug and re-plug the Ethernet cable to the sensor.

Alternating White/Green

During the Intel® RSP Controller application discovery process, the Intel® RSP Sensor must acquire time using the ntp protocol. If the sensor is successful in getting time from the advertised ntp server, the LED will flash White/Green three times.

No action required.
This state should not last longer than 2 or 3 minutes. If sensor does not transition to idle or reading tags than try the following:

  • Verify the date and time on your system clock is correct
  • Verify your security certificates are valid or try generating new certificates.

Alternating White/Red

If the sensor is unsuccessful in getting time from the advertised ntp server, the LED will flash White/Red three times.

  • Verify your edge computer is running and configured as an ntp server. 
  • Power cycle the edge computer.
  • Unplug and re-plug the Ethernet cable to the sensor.

 Purple

During the Intel® RSP Controller application discovery process (if configured to do so), the Intel® RSP Sensor must read the provisioning token out of the embedded NFC tag. If the sensor is successful in reading the provisioning token, the LED will briefly display purple.

  • See “System Provisioning Cluster Tokens” section in the Intel® RSP Controller Application - Edge Computer Software Installation & User Guide. 
  • See the Intel® RSP Android NFC Application document.

Solid Yellow (Idle)

Following Intel® RSP Controller application discovery, an LED state of “solid yellow" indicates that the Intel® RSP Sensor is in the idle state and ready to accept commands.

Normal to see sensor in idle state temporarily if the Intel® RSP Controller application is set to “All_Sequenced” and the sensor is in-between reads.

  • See “Configuration: Clusters” section in the Intel® RSP Controller Application - Edge Computer Software Installation & User Guide.
  • If the Intel® RSP Controller application is setup to run from a configuration file (clusters) than make sure that the sensor has been assigned to a cluster configuration.

Blue

An LED state of “solid blue" indicates the Intel® RSP Sensor is currently in an Inventory Cycle (i.e. transmitting) but not receiving any tag data.

  • Make sure there are RFID tags in the field of view of the sensor

Flashing Blue

Currently in an inventory cycle and successfully communicating with RFID tags.

No action required.

Flashing Red

An LED state of “flashing red" indicates the Intel® RSP Sensor has detected a failure. This will continue until the alert is acknowledged by the Intel® RSP Controller application or the CLI

  • Error conditions can be viewed by going to the Web Admin-Sensor page and selecting “Alerts”.
  • See user guide for a list of possible error conditions.
