  • What environment is recommended for testing an AoA locator and beacon, and for parsing IQ values?

    For best results, keep the beacon within a 90-degree tilt angle of the locator and maintain at least one meter of distance between them to ensure more accurate phase difference readings.
  • What should we keep in mind when installing Bluetooth beacons or sensors in a factory, warehouse, or office building?

    The most important rule is avoid direct contact with metal surfaces. Metal absorbs and reflects Bluetooth (2.4GHz) signals, which can reduce signal strength by 50% or more—leading to poor coverage, lower positioning accuracy, or even failure to connect with gateways. For best performance, mount devices on non-metallic surfaces such as concrete walls, drywall, wood, or plastic.
  • Does Minew’s APP SDK support Go programming language development?

    Our SDK provides APIs only. If you plan to develop using Go, you will need to create a custom plugin bridge independently. Compatibility and success depend on your implementation and testing.
  • Can BLE beacons be modified by unauthorized third parties to alter broadcast content or operational behavior?

    Based on BLE broadcasting principles, broadcast frames can be scanned and retrieved by third parties. However, our devices are protected against direct unauthorized attacks. This is achieved through firmware-level encryption for configuration operations: without the required link key, the firmware will not respond to configuration commands, preventing third parties from modifying device settings. Additionally, upon customer request, our devices can operate in a non-connectable mode to reject all connection attempts, further enhancing operational stability and security.
  • Can unauthorized third parties access BLE beacon broadcast data? Does this compromise data security?

    BLE broadcast data is inherently public and can be scanned by any device. While third parties may capture the payload (raw data), they cannot interpret its meaning without the specific frame parsing protocol.
  • Can Minew’s Beacons support custom firmware to connect with different customer gateways?

    Yes, we can customize the firmware. You need to provide the connection protocol for your gateway, and we will develop the necessary adaptation.
  • When configuring devices with the BeaconSET plus APP, why can’t some Minew devices be connected?

    The BeaconSET plus App scans and displays broadcast signals that meet Minew standards. Devices with different firmware versions might appear, but the App may not support connecting to all versions. Please refer to the device's user manual to ensure you are using the correct App or method for connection and configuration.
  • Can BLE be developed to implement a direction-finding positioning solution similar to UWB?

    If UWB isn't suitable for your project due to cost or other limitations, but you still need similar capabilities, you can use BLE in a few ways: BLE 5.1 with AoA or AoD technology, RSSI measurements with beacons, or BLE combined with IMU sensors.
  • Why did the batch import of MBT02 devices fail on the TagCloud 3.0 platform?

    Please provide the failed import file, deviceImportResult.xlsx. We will analyze the content to determine the cause of the import failure. The error message at the end of the file will help us in our analysis.
  • Why can’t Apple devices select OTA packages in the app?

    iOS devices have permission issues that prevent the app from accessing documents outside the root directory. You can use third-party software to place the OTA package, certificates, and other necessary files in the app directory to make them accessible.
  • How long is your expected delivery?

    Minew has a global customer base and we ship to most countries around the globe. The actual delivery time is subjective to the client's location. We offer several shipment methods to meet your time constraints.

  • Can the E7 remove the battery and support an external power supply?

    Simply solder your own wires and replace the battery with an external power source, or let us customize it for you if you need to ship in bulk.
  • What’s the best way to install a beacon to have the strongest signal and broadcasting range?

    If the installation height is less than 2 meters, the orientation of the three directions doesn't matter much. If the installation height exceeds three meters, the antenna should be placed in the downward position to have stronger signals.
  • What are some suggested deployment ways for MBM01 Ultra-Long Range Beacon?

    The beacon's signal broadcast waveform is heart-shaped, meaning the strength is optimal on both sides of the antenna. Therefore, place the antenna first and position the sides in the aisle for the best signal. Note: If there are multiple beacons in a showroom, you can: 1. Adjust the broadcast strength and shorten the distance. 2. Filter the signal strength using RSSI.
  • How can the P1 beacon be turned on and off without buttons?

    The P1 beacon can only be turned on via magnetic control and turned off through the app.
  • Can I add ACC sensor to MTB02 Paper-battery Asset Tag?

    Yes, there is a space reservation for the extended plug-in.
  • What is the impact on battery life if some tags remain off for 6 months before being turned on?

    According to product tests, the average energy consumption is very low when not turned on. Storing the product for 6 months under suitable conditions has no significant effect on its lifespan.
  • Can Minew’s asset tags identify whether the asset is stacked?

    If it is only necessary to determine whether the assets are stacked or not, a video/image sensor can be useful.
  • What is the operating voltage range of the MTB02 Paper-battery Asset Tag? What about the minimum voltage when not broadcasting?

    MTB02 stops working when the battery voltage falls below 1.2V or 1200mV.
  • Why does the G1-E give error code 671 when trying to get historical temperature data from an MST03 device?

    Error code 671 means the gateway can’t connect to the device. This can happen for several reasons:
    (1) The MST03 is too far from the G1-E, so the connection fails.
    (2) The MST03 has too much historical temperature data stored, which can cause it to disconnect when the gateway tries to retrieve the data.
    (3)The command sent over MQTT has an incorrect password or the wrong MAC address.。
  • Does the MG6 gateway support the AMQP protocol?

    No, it doesn’t.
  • What is the maximum supported SD card capacity for the MG6 gateway?

    It is recommended to use SD cards no larger than 32GB. Cards above this size may have stability issues over the SPI interface, leading to detection failures or frequent I/O errors.
  • Does the MG6 gateway send acknowledgment packets to confirm connection and data transmission?

    It depends on the communication protocol: MQTT: Acknowledgments are handled by the MQTT protocol itself, based on the selected QoS level. HTTP: The gateway expects a 200 status code from the server in response to every HTTP POST request, regardless of whether the uploaded data is empty. TCP: As a transport-layer protocol, TCP does not include application-level acknowledgments. The server must handle packet reassembly manually.
  • Why do multiple MG3/MG4 devices plugged into the same powered USB hub flash red and green alternately, even after successful network and server connection?

    This is caused by insufficient power supply. We recommend using one USB hub to power only one MG3 or MG4 device.
  • Can the MG6 gateway send downlink commands to BLE devices from other manufacturers?

    Currently, it only supports downlink control for Minew BLE devices using our proprietary protocol. However, we have developed a new MG6 firmware that supports standard BLE protocols, which will be released soon.
  • Does the MG3 gateway support communication via SOCKS proxy?

    The MG3 does not support SOCKS proxy communication.
  • Can the MG3 gateway connect to the customer’s Wi-Fi network if port 123 is restricted? Does the local NTP server IP need to be set in advance, or can it be configured manually through the SmartConfig App?

    Restricting port 123 does not affect Wi-Fi connectivity, but it does impact time synchronization and certificate validation. If these features are required, the server IP must be set, and manual configuration through the SmartConfig App is needed. However, our SmartConfig App does not support this feature.
  • Why can’t the MG6 gateway receive downlink commands when using HTTP to communicate with the server?

    HTTP is a client-initiated protocol where the server passively responds to requests. By default, it does not support server-initiated command "push" to the client. For scenarios requiring the server to actively send commands to the gateway or client, we recommend using the MQTT protocol.
  • Does MG7 gateway support ZeroTier Connectivity?

    Yes, the MG7 supports ZeroTier.
  • Does upgrading from legacy G1 gateway to G1-E-grapes gateway require reworking data protocol compatibility?

    Customers who have already integrated the old G1 gateway can easily integrate the G1-E-grapes gateway, as it supports the same data formats (binary, JSON-LONG, JSON-SHORT). However, it's recommended to review the new gateway's data parsing documentation for helpful new features. For new customers or those updating, we offer the JSON-PREPARSED format, which ensures better compatibility and easier configuration with our latest devices.
  • Which reporting protocol is recommended for the G1-E-grapes gateway?

    JSON is the most widely adopted protocol for our G1 gateway. Among available JSON formats, JSON-PREPARSED is strongly recommended due to its unmatched compatibility with broadcast frame parsing and highly intuitive configuration options.
  • Why doesn’t the MWC03 badge report GNSS data according to the configured positioning interval?

    The GNSS interval only defines how often the device retrieves data from the GNSS module. The retrieved GNSS data is then uploaded during the next LTE report cycle, not on a separate reporting schedule.
  • Can the C10 with 13.56MHz NFC be read by an iPad’s NFC reader?

    iPads do not natively support NFC reading. To use this function, an external third-party NFC reader is required.
  • Does the MWC03 smart badge offer SDKs/APIs for platform integration?

    While MWC03 does not provide SDKs or APIs, customers can achieve seamless server-side integration using our Nanolink protocol.
  • The MWB01 tag is similar in size to the AirTag. Can it be used with AirTag cases?

    Yes, the MWB01 has the same size, so customers can use available AirTag cases. We can also assist with purchasing and shipping them if needed.
  • Can the wristband color be customized?

    Yes, custom wristband color is supported. Currently, the available colors are black, white, and gray. For other colors, please provide the details for evaluation.
  • Can I write product MAC addresses or serial numbers to passive NFC tags like the C10 card beacon and MWC01 badge?

    Yes, as long as the information length does not exceed the NFC chip's limit.
  • Does the MWC03 support disabling Bluetooth scanning to report only GPS signals, or disabling GPS to report only Bluetooth data?

    Yes, it supports these configurations and can be integrated with your own platform for remote configuration.
  • How does the MWB01 Dynamic Tag fulfill personnel management?

  • What is the estimated broadcasting range of the C10 card beacon?

    C10 card beacon supports Bluetooth® 5.0 and a 100-meter broadcast transmission range, particularly applicable to indoor settings, such as hospitals and workplaces.
  • How to enable the sleeping mode of B7 Button Wristband?

    After enabling "Trigger Settings" and completing the ACC setup, customers can turn off "Usual Broadcast". This will make the frame broadcast for a configurable period only when ACC is triggered and stop when not triggered. Besides, no firmware update is required.
  • Can the MBT02 Asset Bluetooth Repeater be modified so that only acceleration can trigger scanning?

    Yes, it can be modified. The current MBT02 board has a reserved acceleration sensor; it just requires firmware adaptation.
  • How is a LoRaWAN node’s power consumption managed?

    Nodes are battery-powered and designed for low power use. Sleep modes and optimized transmission intervals help extend battery life.
  • What is the typical maximum communication range between a LoRaWAN node and the network?

    It depends on factors like power, interference, and terrain. Generally, a few kilometers in urban areas, but over 10 km in open rural environments.
  • What are the main ways to configure parameters?

    Via downlink commands. For Class A devices, new settings are received and applied when they next send data.
  • Can a single LoRa device connect to multiple network servers?

    No. Once registered, the device is bound to one server with a unique devaddr. Other servers can't receive its data unless it re-joins and registers with them.
  • How is the timing function in the S4 door sensor?

    The S4 device can only record its own runtime. Accurate timing requires network time synchronization. To improve timing accuracy, our device includes an internal clock crystal. Each time the device connects to the app or gateway to download historical data, it automatically synchronizes time, enhancing the reliability of timing-related operations.
  • What is the operating voltage range of the MSR01 if the voltage cannot be stabilized at 12V during deployment?

    The MSR01 supports an operating voltage range of 10V-25V.
  • Can the MSR01 Millimeter Wave Radar Sensor directly output raw radar detection data?

    Our MSR01 currently does not support transmitting raw radar scan data to third-party systems. Instead, it outputs processed results such as coordinate data and people counting statistics. If you require access to millimeter-wave radar raw data for independent analysis, we can customize the firmware to align with your specific project requirements.
  • Does the MSR01 Millimeter Wave Radar Sensor support reporting cumulative numbers of people detected?

    No, the MSR01 currently supports reporting only the number of people detected within set time periods.
  • Does the S4 Bluetooth® 5.0 Door Sensor support broadcasting and alerting only when a state change occurs?

    Yes, it also supports periodic broadcasting, and the broadcasting interval can be configured.
  • Is it possible to receive and parse MSR01 data on a PC without a Minew gateway?

    For the BLE version of MSR01, a PC cannot directly scan the beacon broadcast data. However, it can be scanned and received using the external Nordic DK tool or by downloading the PC version of NRF Connect. For the WIFI version of MSR01, an additional Minew gateway is not required. The radar detection data reported by MSR01 can be received on a PC via the MQTT.fx client software.
  • Will MSR01’s radar signal cause any harm to human bodies?

    The radar operates at a safe 60GHz frequency, posing no harm to humans. Radar systems, including those operating at 60GHz, are designed to ensure safety within established human exposure limits.
  • What does the MSR01 Millimeter Wave Radar Sensor reply on to recognize people or objects by?

    It utilizes human identification characteristics, which may also extend to animals, but with potential radar interference from metal. Height detection settings can filter out such interference when there's human traffic. Objects can be detected without additional labels, and the algorithm distinguishes automatically between humans and other objects.
