The North Pole Engineering (NPE) CABLE will convert the ANT+ signal from your sensors to a Bluetooth signal that can be picked up by your native Bluetooth 4.0 receiver.
The v1.7.7 firmware update introduced the ability to convert the FE-C smart trainer signal to FTMS, allowing you to use this device to connect your FE-C smart trainer to The Sufferfest App via Bluetooth.
For the initial set up you will want to follow the instructions found on the NPE website: https://npe-inc.zendesk.com/hc/en-us/articles/360026941632-CABLE-Setup-Guide
Once you have connected your ANT+ sensors to your CABLE, don't forget to double tap your iOS home button and swipe the CABLE Config app up to completely close it.
Now it’s time to connect the CABLE device in The Sufferfest App. Open The Sufferfest Training System App and select a ride. Click on the "Add Devices" button under the "Devices" tap. Ensure that your CABLE is awake and you should see the option to connect to it.
Once connected, you will be able to select which data you want to be displayed from the CABLE.
Troubleshooting tips: The most common issues with connecting the CABLE device are:
1- not completely closing the CABLE app before opening The Sufferfest App and
2- the CABLE device being off when you try to connect with The Sufferfest.
Be sure to close the CABLE app as described above and check for the flashing green light on the device. If you encounter any issues during setup please email firstname.lastname@example.org and we will be happy to assist you.
