Frequently Asked Questions about CABLE – FAQ

Updated 07/30/2018


Q: Can I use CABLE with my Android phone or tablet?

A: Currently, the CABLEConfig app is only available for iOS. Once your CABLE unit is configured you can use it with any hardware that uses BLE sensor connections. This will work with Android, iOS, Apple Watch, Windows, etc. 

Q: When do you use CABLE Config?

A: The CABLEConfig application is ONLY needed to setup/pair your sensors with your CABLE unit. You do not need to use CABLEConfig anymore thereafter, unless you want to change or add sensors, update CABLE firmware, or test out your sensors. Leaving CABLEConfig running in the background can cause connectivity issues. It is not needed to provide any bridging connection to your BLE service application, such as Map-My-Fitness. All the data sent from CABLE to your app comes through the BLE services generated by the CABLE device. 

Q: What does the LED indicate on the CABLE?

A: There is a single two-color LED in the CABLE.

  • Double Red Flash: Searching for ANT+ Devices
  • Double Green Flash: CABLE is connected to a mobile device and connected to the ANT+ sensors
  • Single Green Flash: CABLE is available to connect to a mobile device/fitness app

Q: How close must my CABLE be to pair with my sensors?

A: The CABLEConfig application will show all active ANT+ sensors in the vicinity of the CABLE while performing a scan for sensors. On the screen for selecting sensors, there is an indicator on the right side of the row which shows the signal strength. We recommend keeping the sensors within three meters to ensure stronger signal strength. 

Q: How do I turn my CABLE on?

A: To turn it on, double tap on the front (label) side of the device with your finger. Tapping the unit on a surface will work but may require a series of taps. 

Q: How do I turn my CABLE off?

A: The CABLE will turn itself off when the BLE connection is disconnected and the ANT+ sensors are no longer tracking. If you are running CABLEConfig, you can select the “Power Down” option in the control menu. Using the “Power Down” option can help preserve the battery life of your unit. 

Q: How do I change the battery?

A: On the short end of the case, insert a coin, paperclip, or something similar, into the notch to snap open the case. Then replace the 2032-coin cell battery making sure the positive (+) side is face down in the battery slot. Then, snap the case back together, making sure the battery end connects with the negative terminal on the opposite half of the case. 

Q: How do you attach, mount, or use CABLE during your workout?

A: CABLE should be located within three meters of your sensors and display device during your workout. We recommend mounting it on your bike with a zip-tie or carrying it in a saddle bag. It will work at longer distances, but it may periodically lose connection during a workout. For a list of compatible applications and known application issues, see here.

Q: Can you create multiple sensor sets with CABLE?

A: Yes, CABLE allows you to create multiple sets, but only one can broadcast at a time. Tap on the Menu button and select “Switch Sets”.

Q: Can I have multiple heart rate monitors in the same set?

A: No, since there is only one BLE service for heart rate on the CABLE unit, only one heart rate monitor can be paired in a set. This is also true of other types of sensors.

Q: How do I use the motion/theft detection feature?

A: In the CABLEConfig app, tap the menu button and select “Motion Detection”. Anytime your CABLE unit is moved, you will get a notification on your iPhone. The CABLE unit and Phone must be within about 10-15 meters to use this feature. (Note: CABLEConfig must remain running on your iPhone to use this feature. You need to select “Motion Detection” every time you want to turn the feature on.)

Q: Does CABLE have a warranty?

A: You can find details on the twelve-month limited warranty in the Setup Guide or here.

Q: Does CABLE allow control of resistance based training devices?

A:  CABLE now supports the BLE Fitness Machine Service (FTMS) for controlling controllable ANT+ FE-C and ANT Saris CycleOps trainers.  The application on the mobile device needs to support FTMS for the feature to work.  The current list of supported apps is TrainerRoad, Sufferfest, and Kinomap.  Other applications are in the works.  If you are using the FTMS service you should connect the FE-C ANT+ profile or the Saris data service to the FTMS BLE service using the CABLEConfig app.  Configuring the CABLE using the CABLEConfig app involves a multiple step process.  First you need to activate the ANT+ sensor then scan for the sensor by selecting the operation in the menu.  Once the sensor is selected and saved, you then move on to assigning the ANT+ sensors to the BLE services.  In the case of FE-C all you need to select is the FTMS service and make sure the FE-C profile is selected.  If you have a secondary speed or cadence sensor you would like to use in addition the FE-C device and have setup CABLE to track the sensor you can select these ANT+ profiles as the source for the data rather than the FE-C profile.  Once the profiles and services are selected you save the setup and move on to verifying the flow of ANT+ data to the BLE services.  This is shown in the third tab in the app.  You can test the available control functions by tapping on the BLE service and selecting the available adjustable settings on the FE-C enabled ANT+ device utilizing the FTMS BLE services.  At this point you are done with the CABLEConfig app.  Simply close the app and move onto using the ANT+ FE-C device with your FTMS enabled fitness application via the CABLE connectivity.

Q: Does CABLE work with Saris CycleOps/PowerTap Trainers? 

A:  The older generation Saris CycleOps trainers that support the legacy custom ANT protocol can be controlled via the CABLE from apps that support FTMS BLE control.  To configure the CABLE to track these devices you will need to use the CABLEConfig application and select the special feature to scan for Saris devices.  This puts the CABLE into a special mode that support the Saris specific proprietary interface.  Once the Saris device is selected and saved, you then move on to assigning the ANT+ sensors to the BLE services.  In the case of Saris CycleOps and PowerTap devices all you need to select is the FTMS service and make sure the CycleOps/PowerTap profile is selected.  If you have a secondary speed or cadence sensor you would like to use in addition the CycleOps/PowerTap device and have setup CABLE to track the sensor you can select these ANT+ profiles as the source for the data rather than the CycleOps/PowerTap profile.  Once the profiles and services are selected you save the setup and move on to verifying the flow of ANT+ data to the BLE services.  This is shown in the third tab in the app.  You can test the available control functions by tapping on the BLE service and selecting the available adjustable settings on the CycleOps/PowerTap device utilizing the FTMS BLE services.  At this point you are done with the CABLEConfig app.  Simply close the app and move onto using the CycleOps/PowerTap device with your FTMS enabled fitness application via the CABLE connectivity.

Q: Does CABLE work with Concept2 trainers? 

A:  The CABLE works with the PM4 consoles with updated FW to support the FE broadcast mode.  Refer to Concept2 documentation for details on setting up the broadcast mode.  You may need to enable the FE broadcast mode each time you power up the console before CABLE can start tracking the device.  Since the Concept2 trainers are not controllable via the wireless interface you can choose which BLE service you would like to map the ANT+ FE profile through.  If your fitness app of choice supports FTMS you will want to choose this service since it typically can combine more ANT+ services together into a single FTMS service and it also supports the rower specific equipment type.  If your chosen fitness app does not support FTMS then you can route the ANT+ FE data to the Cycling Power Service (CPS) and the Cycling Speed and Cadence Service (CSCS). 

Q: Does CABLE prioritize ANT+ sensor types?

A:  CABLE can be setup to track a single instance of each type of supported ANT+ sensor.  The ANT+ sensor profiles can then be routed to the appropriate BLE service.  For example, if you have a 4iiii Precision power meter and you would like to use a Wahoo magnetless RPM sensor, you can pair the ANT+ Bike Power profile on the 4iiii device and the ANT+ Bike Cadence profile on the RPM and route the power from the 4iiii and the cadence from the RPM to the CPS generated by the CABLE.  The fitness app on the mobile device will then use the power from the 4iiii and the cadence from the RPM.  This typically is not possible to assign the priority using the BLE services from both devices.  The routing of the ANT+ profiles to the BLE services is setup using the CABLEConfig app in the center tab routing section. 

Q: Does CABLE support multiple ANT+ sensor?

A:  Yes,  The CABLE can track up to to five (5) unique ANT+/ANT sensor types and route the data to a viariety of BLE services.  The CABLEConfig app is used to scan for active sensors and route the profile data to the BLE services of your choice (CPS, HRX, CSCS, RSCS, FTMS). 

Q: Can CABLE combine ANT+ sensors into single BLE services? 

A:  Yes,  CABLE enables routing of ANT+ profile data into individual or multiple BLE services. 

Q: Can I use CABLE with appleTV? 

A:  Pro Tip,  CABLE is uniquely setup to work with appleTV.  Currently appleTV only allows two BLE connections in addition to the remote.  If you have three BLE sensors feeding into your fitness application running on appleTV you will not be able to use all of them.  To solve this problem, simply use the ANT+ channel on the dual mode BLE/ANT+ sensors and combine them together using CABLE.  CABLE will only consume one BLE connection on the appleTV and provide multiple BLE services to appleTV on that one connection.   

Q: How can I disconnect CABLE from an appleTV application?  

A:  First of all, you should check the CABLE unit to see if it has an active BLE connection before trying to disconnect it from a device.  If there is not an active connection there is no reason to disconnect.  If the CABLE has an active BLE connection it will be indicated by a double flash of either the green or red LED.  Green indicates it is tracking all the configured ANT+ sensors or it has timed out attempting to track them.  Red indicates the CABLE is attempting to find one or more of the configured ANT+ sensors.  The CABLE will only scan for each configured sensor for approximately 40 seconds each.  If it cannot find the sensors in the time it will stop searching so it can conserve the battery.  If the CABLE is bumped after it has stopped searching, it will resume the search and activate the red LED flash pattern. 

Q: How can I be sure CABLE does not have an active BLE connection? 

A:  If the CABLE unit does not have an active BLE connection and it is turned on, it will have a single flash of the green LED.  

Q: How long will CABLE run a fresh battery? 

A:  This is dependent on many factors.  The largest consumer of energy in the CABLE is the radio searching for ANT+ sensors.  If the CABLE is setup to track sensors that are not typically present when you are actively using it to monitor data it will have the red LED active and be consuming a maximum amount of energy.  The search time will only be 40 seconds per sensor, but it will resume searching if it detects motion.  Under normal operation tracking a couple ANT+ sensors you should expect the CABLE to last for months using it up to 10 hours a week. 

Q: What should I do if CABLE is flashing both the red and green LEDs at the same time? 

A:  First, replace the battery. If you have a CABLE that is flashing both the red and green LED at the same time, you will need to get a replacement unit.  Please contact NPE at to request your replacement. 

Q: What should I do with a dead coin cell battery?

A:  Please consult with your local recycling center for instructions on how you should dispose of your batteries.
