General

The status LED lights of the electronics do not light up after switching on.

1. Switch the electronics off and on again (changing the slide switch position, see Control elements electronics).
2. Make sure that the electronics are switched on (changing the slide switch position, see Control elements electronics).
3. Make sure that the battery is not empty by charging the sendance-grid for at least 2 hours via micro-USB with a USB charger (see Control elements electronics), then repeat steps 1-2.

The red status LED lights up continuously.

Try using the "Reset" button (see Control elements electronics) and see if the blue LED starts blinking normally again. Otherwise, please contact us.

Connectivity

I cannot establish a Bluetooth connection (Bluetooth device list is empty) or the connection fails.

1. Switch the electronics off and on again (see Control elements electronics).
2. Follow the steps in Usage.
3. If this is not successful, make sure that the blue status LED starts blinking after power on, otherwise follow the steps in General > "The status LED lights of the electronics do not light up after switching on".
4. If this is not successful, delete the pairing with the sendance-grid device in the Bluetooth settings of your operating system and repeat steps 1.-3.
5. This is not successful, delete all cookies for sendance.at and reload the web application.

The Bluetooth connection breaks in the Live Data view.

1. Make sure that the user of the sendance-grid is not more than 5-10 meters away from the receiving device, their PC (depending on the receiving range of their PC), and especially not in any other room.
2. Make sure that there are no extreme amounts of "smart devices" such as laptops, PCs, IoT devices, etc. in their immediate vicinity (such as in RF labs, large crowds, or similar).
3. If the connection is still not stable despite these measures, please perform step 4 from "I cannot establish a Bluetooth connection (Bluetooth device list is empty) or the connection fails".

What happens when a device looses connection during Online Recordings?

No data is recorded from a device while its connection is interrupted. The recording may continue though until it is explicitly stopped. To continue recording the device's data, reconnect the device! Afterwards, a "data gap" may be visible in the data visualizations. See Data Viewing and Recording > Create Recordings for more details.

Visualization

The pressure in live mode is consistently 0 or too low.

1. Make sure that the sendance-grid was not loaded when connecting to the sendance-cloud, otherwise reconnect them (see Usage).
2. Unload the sendance-grid and use the function "Tare" in the device quick settings.

One of the promised views is not available to me.

1. Make sure that you are in the correct mode. Some analyses are only available when viewing an existing Recording and not in Live Data (see Workspace and Data Viewing & Recording).

Compatibility

My PC has no Bluetooth or it’s not working in a stable manner (e.g. Surface Pro 3)

We recommend using a USB bluetooth dongle (Bluetooth 4.0 or higher). To install:

1. Delete existing pairings with sendance-grid devices in the Bluetooth settings of your operating system (see this How-To for Windows).
2. Plug in the USB bluetooth dongle.
3. Reboot your PC. Afterwards, the USB bluetooth dongle should be used automatically.
4. Switch the electronics of your sendance-grid device off and on again (see Control elements electronics).
