The absence of a cellular or WiFi connection, or failure to ping a test server, produces an informative No Internet error.
This will not prevent a user from starting a Bluetooth study, however the remote Nexus360 logging function will not function, and the user must connect to the internet for eventual study upload.
Unable to Locate Somfit
Unable to Locate Somfit
When the study first starts, it attempts to locate the Somfit, and connect to it over Bluetooth.
This will typically take less than 20 seconds before the check displays a Green Tick icon, and a message that the Somfit has been located.
However, after 30 seconds if the device has not been located, a message will appear.
This is to prompt the user to ensure that the device is in the same room as the phone, in Bluetooth proximity.

Is Somfit charged?
Is Somfit charged?
If the Somfit is not located after a further 15 seconds, a separate dialogue will be displayed.
The second message is intended to prompt the user to consider if they remembered to charge it, and whether it may have run out of battery.
If the battery is not dead, the user can confirm this by noting a flash of the green LED every 10 seconds if it has not yet connected.
If the user has followed instructions correctly (ensuring the device has been charged and is in Bluetooth range), then it is possible that there is either a Somfit hardware fault, or an incorrect device has been assigned for an appointment.

If the user presses ‘No’, then the application will inform them that the device must be charged prior to starting a study. If the user instead presses ‘Yes’, then the application will inform the user that it was unable to connect to the respiratory module.
If the user has followed instructions correctly (ensuring the device has been charged and is in Bluetooth range), then it is possible that there is either an hardware fault, or an incorrect device has been assigned for an appointment.
Stuck on Low Battery
Stuck on Low Battery
After connecting to the device, the Somfit application will check the device battery.
Typically within 10 seconds the tests will either pass indicating sufficient battery, or explicitly state a low battery message.
If there is no indication after 30 seconds that battery is either sufficient or low, then there may be a possible hardware with the Somfit.

Failed Signal Check
Failed Signal Check
Failed Impedance Check
Failed Impedance Check
After the battery has been measured, the Somfit application will run an impedance check.
This may take up to a minute. If measured impedance is acceptable, then the Somfit Study Test screen will close.
If the test is unsuccessful, a message will be displayed indicating that the electrode may be making poor connection with the forehead. The user should press on it and press Retry. After pressing the Retry button, the impedance test is restarted, and may take up to a minute to finish.
Repeated failure of the impedance test should not be a reason for the user to cancel the study.
There is some normal variation of skin impedance depending on the quality of the skin preparation, the subject’s skin, and motion during the test. A good quality signal may still be obtained even if the impedance test has failed.
Stuck on Thoracic Check
Stuck on Thoracic Check
The series of respiratory module checks includes a test of the thoracic band connection.
If both inductive band studs are detected, then the test screen will indicate a successful result and display a corresponding message.
If no band is detected then the test screen will remain with the test pending.
Cases where no band is detected include
- The band is not applied to the device at all
- The band is not correctly applied and has not clipped in to the stud
- The ECG leads have been applied to the band connector studs
- The band has a break in it preventing an electrical connection from being made
- The device stud connectors are detached from the PCB
If a patient reports this error despite correct application, it is highly recommended to confirm it in the laboratory.

Stuck on ECG Check
Stuck on ECG Check
The series of respiratory module checks includes a test of the ECG lead connection.
If skin contact with both ECG leads are detected, then the test screen will indicate a successful result and display a corresponding message. Note that passing this test in itself does not guarantee a successful study, as signal quality may still vary depending on electrode application.
If the ECG leads are not detected then the test screen will remain with the test pending.
This may be associated with damaged electrode leads, poor connection between leads and device studs, or damage to the respiratory module device.
If a patient reports this error despite correct application, it is highly recommended to confirm it in laboratory.
Stuck on Nasal Cannula Check
Stuck on Nasal Cannula Check
The series of respiratory module checks includes a test of the nasal cannula signal. This may take a minute to complete.
If a breathing signal is detected then the test screen will automatically close, and the patient is informed to continue the study.
If a breathing signal is not detected, then the test screen will remain with the test pending.
This may occur if the nasal cannula is improperly applied to the device or patient.
This may occur if there is damage to the device.
This may occur under some normal conditions, such as shallow patient breathing, or breathing through the mouth.

Study Finished Early
In the correct workflow sequence, the user will wake up, unlock the phone, and press the end study button. Once the end of study is confirmed, the app will return to the home screen and start uploading the study.
If the user returns to the application in the morning, and the home screen displays the study uploading without manually stopping the study, an error may have occurred.
This is possible in a few cases:
- The app was terminated was by the Operating System, typically due to battery or memory constraints
- The app crashed
- The user ‘swiped upp’ on apps before going to bed, intentionally closing it
- The phone ran out of battery prior to study completion
To reduce the chance of these errors it is recommended users leave the phone charging on the bedside table and avoid using other applications before going to bed.
