Bluetooth issues

Issues with the Bluetooth signal dropping during a session

Bluetooth low signal icon If you see a red Bluetooth notification appear it is likely that the epihunter app is not receiving all of your data packets due to Bluetooth low energy signal interference. Much like other wireless signals, Bluetooth operates on a 2.4 GHz frequency. This means anything transmitting on or interfering with that frequency can also interfere with Bluetooth.

As Bluetooth signal interference and dropouts are related to the setup of Bluetooth technologies and not something we at epihunter can control, it is not an issue we can fix for you. And the epihunter app can only work with the data it receives from the headset.

While we cannot solve the issue, we do have included below the most common causes for interference and dropouts so you can try to find a solution via a process of elimination.

Most common causes for potential Bluetooth signal dropouts:

  • Dying sensor battery: If you have not charged the battery of your headset recently, try to charge it first (30-45 minutes to full charge).
  • Wireless signal interference: This includes any devices that transmit wireless signals or electromagnetic fields. See our example list at the bottom of the article.
  • Fans: These generate an electromagnetic field around them that can block signals. Position fans so they are not in a direct line between your sensors and smartphone.
  • Wireless computer accessories: The USB dongle for your wireless mouse, keyboard, or other accessory can cause interference.
  • Physical barriers: Any object that obscures line of sight from your smartphone to your headset can cause signal loss.

Potential wireless signal interference sources:

  • Bluetooth headphones, speakers, or hearing aids
  • Microwave ovens
  • Direct Satellite Services (the coaxial cables and connectors can cause interference)
  • Power sources (includes power lines in a wall)
  • Cordless telephones
  • Wireless video transmitters (e.g. Chromecast, AirPlay, etc.)
  • Certain external monitors and LCD displays
  • Any devices that use a cable to connect to a computer or power source
  • Anything else that transmits a wireless signal, from routers to baby monitors

If you are still experiencing dropouts after eliminating the above causes, we can try and help you investigate.
our Support team and we will help you further. Send us any description as well as pictures (of the location where you use epihunter, the headset and its sensors, the phone you use for epihunter) and some app screenshots (if applicable).
