Why buy four anchors if three anchors can calculate a position?
UWB PositioningAnswer
1) Tags should operate inside the anchor coverage area. Four anchors can cover a rectangular area rather than a triangular one; the source describes an approximately doubled coverage area. 2) Wireless ranging can fail. With four anchors, a position can still be calculated when ranging to at least three succeeds; a three-anchor setup needs all three measurements to succeed. 3) A four-anchor, one-tag setup can be reconfigured as three anchors and two tags to learn multi-tag operation. 4) Four anchors can support 3D positioning when the installation spans length, width and height in a 1:1:1 arrangement.
Development and interfaces

Yes. Haoru provides the RTLS1 PC application with 2D/3D map display, real-time trajectory tracking and data forwarding.
Development and interfaces
What should I check if positioning accuracy is poor?
UWB PositioningAnswer
Check: 1) anchor coordinates; 2) anchor mounting height, with the source recommending at least 1.8m above the floor; 3) ranging and communication quality for each anchor; 4) obstructions; 5) whether all anchors are coplanar; 6) whether the tag is far outside the area enclosed by the anchors.
Development and interfaces
Do packages 7499 and 5999 include the same technical materials?
UWB PositioningAnswer

Development and interfaces
What does the gateway module do?
UWB PositioningAnswer
A normal test setup connects a module to the PC by USB. The gateway adds Wi-Fi communication so the module can communicate with the PC wirelessly. It is an optional communication accessory rather than a requirement of UWB positioning itself.
Development and interfaces
How do modules connect to other embedded devices?
UWB PositioningAnswer
Through the onboard UART-TTL interface.
Development and interfaces
How do the modules connect to a PC?
UWB PositioningAnswer
Through USB. In the referenced four-anchor system, only one anchor needs a USB connection to the PC.
Development and interfaces
What communication range is available between an anchor and tag?
UWB PositioningAnswer
Suitable models can exceed 200m in open, unobstructed line-of-sight conditions. Walls, metal and indoor attenuation reduce practical coverage. The referenced indoor planning guideline is a 30–80m coverage radius per anchor, subject to the specific model and site survey.
Development and interfaces
Can the modules interact with an iPhone?
UWB PositioningAnswer
The referenced ULM3-FIRA configuration supports compatible iPhone 11 and later devices running iOS 15+ through FiRa-related integration. Standard configurations do not provide that capability. Verify the applicable protocol and firmware.
Development and interfaces
Is the positioning system ready to use, or does it require development?
UWB PositioningAnswer
The system includes established positioning functions. Read position data through its interfaces for your application, or use the supplied functionality and available source code for custom product development.
Development and interfaces
How do the legacy RTLS1, RTLS2 and RTLS3 platforms differ?
UWB PositioningAnswer
RTLS1 is an open-source STM32 development kit for evaluation, low-level UWB work, product development and integration. RTLS2 is a closed-source deployment-oriented device with Ethernet and a web interface. RTLS3 is an open-source Arduino development kit with a lower learning barrier for evaluation and academic projects. These are platform-level descriptions. Confirm the hardware revision, firmware and delivered code/licence scope for an existing installation; the description does not imply that every connected module has open internal firmware.
Development and interfaces
What can a Haoru UWB positioning system do?
UWB PositioningAnswer
Haoru supplies UWB RTLS hardware and basic data interfaces for tracking people, vehicles and assets. Depending on the configuration and environment, it provides centimeter- to submeter-level real-time X/Y/Z position data. Integrate these interfaces into an MES, WMS, security platform or other application to implement trajectory tracking, geofencing and statistics.
Development and interfaces
Can I obtain positioning data on the same PC that runs the application?
UWB PositioningAnswer
Yes. View it in the HR-RTLS application or receive it through the data-forwarding interface on the local PC.
Development and interfaces
Can tag data be read without internet access?
UWB PositioningAnswer
Yes. The positioning network is a local system; reading its data does not require an external internet connection.
Development and interfaces
Is the standard positioning solution a 3D system?
UWB PositioningAnswer
The standard solution mainly targets 2D floor-level tracking of people, vehicles and assets. Precise XYZ positioning requires suitable geometry: at least four anchors, with six to eight recommended, distributed across a roughly 1:1:1 space. Z accuracy degrades with obstructions or narrow and non-ideal layouts. For floor identification, assess separate anchor deployments on each floor and determine the floor in your application from anchor or zone IDs. The standard PC application does not provide a complete automatic multi-floor system; that integration normally requires custom development.
Development and interfaces
Can firmware be upgraded?
UWB Positioning, Automatic Following Kits, Following VehiclesAnswer
Yes. Supported controller firmware can be programmed using STLINK after setting up the required development environment.
Development and interfaces
What development support is available?
UWB Positioning, Automatic Following Kits, Following VehiclesAnswer

Development and interfaces
Can the normal module firmware output raw CIR?
UWB Positioning, Automatic Following Kits, Following VehiclesAnswer
Normal ranging/positioning firmware outputs processed ranges or angles rather than raw channel impulse response data. CIR acquisition requires the compatible dedicated firmware described in the CIR development materials.
