If you imply the BLE scanning, the DSGW-030-2 Bluetooth Wi-Fi gateway continuously scans for nearby Bluetooth devices in real-time but does not upload the device list in real-time. Instead, it periodically uploads the list of scanned devices to your server at specified time intervals. As of now, the maximum number of devices that can be included in this list is 400 devices. This functionality allows you to monitor and track nearby Bluetooth devices efficiently without overwhelming the server with real-time data updates.

Is the communication between the gateway and the sub-device secure?

The use of AES (Advanced Encryption Standard) encryption for communication between the gateway and sub-devices (Zigbee, BLE, and Z-Wave) is a strong indicator of security measures in place. AES is a widely recognized and trusted encryption algorithm known for its robust security. 

Is the communication between the gateway and the platform secure?

In order to ensure that all communications between the gateway and the platform are kept private and secure, MQTT TLS/SSL can be used for those exchanges. Using MQTT with TLS/SSL for communication between the gateway and the cloud platform ensures that the data is encrypted and secure during transmission, providing confidentiality and data integrity.

Whether the gateway can connect to third-party Zigbee devices?

The universal Zigbee gateway will be able to adapt and transfer data to the cloud transparently as long as the device is built in line with the standard for the Zigbee 3.0 protocol.

How far is the transmission distance of the gateway? Does a room have to have a gateway? Can signals go through walls?

The transmission distance of the DSGW-030 Wi-Fi gateway’s Zigbee function can reach up to 100 meters in open environments. However, the actual coverage and signal strength can vary based on several factors:

  • Environment: The specific environment in which the gateway is deployed can significantly impact the transmission distance and signal strength. Factors like walls, obstacles, interference from other electronic devices, and the presence of reflective surfaces can attenuate the Zigbee signal.
  • Gateway Placement: The placement of the gateway within the environment also plays a crucial role. Placing the gateway in a central location with minimal obstructions can help maximize signal coverage.
  • Walls and Obstacles: Zigbee signals, like most wireless signals, can have difficulty penetrating walls and solid obstacles. The signal strength will weaken as it passes through walls, reducing the effective range.
  • Interference: Nearby electronic devices operating on the same frequency or in the 2.4 GHz range (common for Zigbee) can introduce interference, potentially affecting the signal quality and coverage.
  • Signal Repeaters: In larger or obstructed environments, you can use Zigbee signal repeaters to extend the coverage and improve connectivity between the gateway and Zigbee devices.

Regarding whether a room must have a gateway, it depends on the specific use case and the desired coverage area. In some scenarios, a single gateway may cover an entire room, especially in smaller spaces. However, in larger areas or environments with many walls and obstacles, you may need multiple gateways or repeaters to ensure consistent coverage throughout the space.

Gateway AP network is repeatedly connecting/disconnecting, is it normal?

Frequent connecting and disconnecting of sub Wi-Fi devices from the gateway’s AP network, especially when the gateway is without an Internet connection, may not be normal behavior and can indicate an issue with the network configuration. Disabling and stopping the “wmsgd” service, which might help address the issue. You could log in the gateway using ssh and run commands /etc/init.d/wmsgd disable;/etc/init.d/wmsgd stop for solving the problem.

I have configures AWS but I cannot add the certs. I have ssh’ed the files to the gateway as Upload feature doesn’t work. I then then choose the files but instead of selecting them it deletes them from the gateway and sets them back to the defaults certs.

It seems like you are encountering an issue with adding certificates to your DSGW-030 Wi-Fi gateway on AWS, where the uploaded certificates are not being retained and revert to default. You could update the gateway image to the latest version from the resource center. Newer firmware or software updates may include bug fixes or improvements that resolve this issue. Know more about AWS IoT Core API gateway here.

When using the gateway, we found that the signal of the end devices including water leakage sensors and humidity and temperature sensors were sometimes strong and weak, and the device dropped offline. Through on-site inspection, we found that the gateway devices had a network, but the server received push information not from the gateway. 

For signal strength: Please verify that the placement of your gateway provides adequate coverage to the entire area where your end devices are located. Thick walls or obstacles can significantly weaken wireless signals. You can try repositioning the gateway to a more central location within your network to improve signal strength and coverage.
