Using LumenRadio BLE (Bluetooth)

In This Article

This is a quick guide covering how to use a LumenRadio BLE connection to send DMX data to fixtures. With a compatible LumenRadio BLE device, additional networking hardware is not needed in order for Slyyd to communicate with fixtures. For example, all Vortex fixtures support direct control over LumenRadio BLE, and can then transmit that data to other fixtures using the Vortex’s CRMX transmitter function.

BLE is not intended to connect to each fixture individually. Since Slyyd has a limit of 2 Connections, it is recommended to use BLE from the Slyyd app to a single device/fixture, and then use that device/fixture to talk to additional fixtures patched within the BLE Connection. A Vortex can listen to a BLE signal, then repeat that over CRMX to other fixtures, which has a much farther range than BLE.

Creating a BLE Connection

A BLE Connection can be established during project creation, or afterwards from the settings menu of a project.

When creating a new project, tap ‘Add LumenRadio BLE’ to start. If this is the first time creating a BLE Connection, Slyyd will need permission to use Bluetooth, so make sure to choose ‘Allow’ when prompted.

A list of available BLE devices will then be shown on the Add Connection screen. If no devices appear, make sure that LumenRadio BLE is enabled on the device. On a Vortex, the setting is found under CRMX settings.

If there are multiple BLE devices listed, tap ‘Identify’ next to a device, causing it to flash. It is recommended to choose the device that will be closest to Slyyd for a BLE connection, considering Bluethooth’s range is limited. Tap the desired fixture to connect. The Connection name can be edited as a reminder of which fixture it is connected to, for example.

Tap ‘Save’ to finish creating the connection. After the connection is established and the project created, fixtures need to be patched into the Connection. For help with patching, see the Patching and the DMX Map article.

When troubleshooting a BLE Connection, it may be necessary to choose "Forget this device" from the iPhone or iPad's Bluetooth settings. This only applies if a BLE pin was assigned to the device using the CRMX Toolbox app, otherwise the BLE device will not show up in the Bluetooth settings page when it is not connected. Setting a BLE pin forces the Apple device to permanently remember that connection, which can cause issues when creating connections from different projects.

DMX Smoothing

LumenRadio BLE responds slower than an sACN connection. Therefore it can be helpful to enable DMX smoothing on fixtures that support the feature, like the Vortex, in order to produce smoother transitions. DMX smoothing can be enabled from the Fixture tab of the Slyyd App for Vortex profiles that support Control Channel. For more information on control channel, see the Control Channel article.
