What is a Bluetooth gateway?

The Bluetooth Gateway is an IoT device that uses Bluetooth and the internet to shuttle data from a user’s WHOOP sensor to the WHOOP cloud without the need for a mobile phone or app.

Do users have to interact with the Bluetooth gateway in order to upload their data?

No, the system passively connects and uploads the user’s WHOOP data when they’re in the vicinity of the gateway. 

Is the Bluetooth gateway system secure?

Yes, the Cassia Gateways include an integrated TPM chip for end-to-end security. Additionally, the WHOOP gateway uses a secure MQTT connection to send and receive data from the cloud.

How do I know which gateway model I need?

This will depend on the application and/or use case. Generally speaking, the model X-2000 is intended for applications or scenarios where long-range connectivity is desired and where multiple end-users / sensors will be connecting and uploading data via the gateway. The model X-2000 can work indoors and is weather-proof to work outdoors.

The model E-1000 is intended for applications or scenarios for shorter-range connectivity, where 1-3 users/sensors will be connecting and uploading data via the gateway. This model is ideal for residential or small office locations.

How many sensors can connect and upload data to one gateway?

The model X-2000 currently supports up to 10 WHOOP sensors simultaneously connected and uploading data. The model E-1000 supports 1-3 WHOOP sensors simultaneously connected and uploading data.

What type of internet connection do I need in order to use the Bluetooth gateway?

An ethernet (wired) connection is required in order to use the WHOOP Gateway. Both models support Power over Ethernet: 802.3af/at a compliant source. 

Can the Bluetooth gateway work over wifi?

At this time, wifi connection to the internet is not supported. We prefer that an ethernet connection be utilized instead.

What kind of power does the Bluetooth gateway need?

The model E-1000 uses a 5V power adapter. The model X-2000 uses a 12V power adapter. Both models support Power Over Ethernet, POE. Note: Do not plug in the power adapter if using POE.

Where should the Bluetooth gateway be placed?

The model X-2000 can be placed on a desk or office furniture, and it includes a pole or wall bracket for easy installation. The model E-1000 can be placed on a desk (or office furniture). 

We recommend placing either gateway in an open area. Avoid using enclosures or cabinets. The Bluetooth signals are affected by building structures such as metal, cement, and brick. We recommend placing the gateway within the same area where the end-user will be localized in order to ensure the strongest connectivity and fastest data upload. 

If users will be on multiple floors, we recommend placing a Bluetooth gateway on each floor.

What happens if the power goes off?

The system will be interrupted if a loss of power were to occur. Once the power is returned, the system will reboot itself and return to normal functionality as long as an internet connection exists. The Gateway will appear ‘offline’ on the WHOOP Unite dashboard after 15 minutes of inactivity.

What happens if there is an internet outage?

An internet outage will interrupt the system. Once the internet connection resumes, the system will reboot and return to normal functionality. The Gateway will appear ‘offline’ on the WHOOP Unite dashboard.

What are the Bluetooth modes that the system uses?

The WHOOP gateway can operate in one of two modes: Assigned or Bluetooth Roaming.

The Assigned mode requires that a WHOOP sensor be assigned to a particular Bluetooth gateway to which it will connect and upload its data to the WHOOP cloud. This mode limits the number of simultaneous connections and data uploads to a maximum of 10 WHOOP sensors per gateway. 

The Bluetooth roaming mode allows sensors to freely connect- and upload their data to multiple gateways that are within various locations within a campus. Bluetooth roaming increases the throughput of the system by allowing sensors to continually upload data via multiple hubs. 

How long does it take to upload data via the Bluetooth gateway?

The data upload speed or bandwidth will depend on the data that is currently in the WHOOP sensor’s memory (backlog) since its last upload. In other words, sensors having 1 hour of data in memory or backlog will upload data in a few minutes, compared to a sensor that has 24 hours of data backlog, which may take up to 1 hour. This also depends on the number of sensors that are simultaneously uploading data. 

How much data can a WHOOP 4.0 hold in memory? 

A WHOOP 4.0 can hold up to 3 days of data in memory or backlog before it begins deleting the oldest data packets. The WHOOP sensor will continue saving data as long as it has battery power.

Which WHOOP sensors are compatible with the WHOOP gateway?

WHOOP 4.0 sensors are only compatible with the Bluetooth gateway system. The system does not support 3.0.

Can the WHOOP 4.0 also be connected to a mobile phone while connecting to a Bluetooth gateway?

No, the WHOOP sensor can only be connected to one Bluetooth ‘central’ at a time.

How do I check the battery level (if I’m not using the mobile app)?

The WHOOP 4.0 has an LED that can indicate the level of battery charge. The LED is located on the side of the device. Remember to open the clasp in order to view the LED. Double tap on the WHOOP sensor to view the LED color corresponding to the battery level.

The LED indicates Battery level: green: 50-100% charge, yellow:  20-49% charge. red: less than 20%.
