How to use the RSSI Signal with Noxturnal and the Nox A1s and Nox C1sĪs mentioned in the introduction about RSSI, think about this signal as providing a rough estimate of the strength and reliability of the Bluetooth transmission between the Nox A1s and Nox C1.
The signal properties can be adjusted as below: This will add an empty sheet to the current workspace layout.įrom here go to the signals inspector menu on the right (1) of the window and locate or search for RSSI (2) to add the signal to the empty sheet (3). It is also possible to create your own RSSI sheet in Noxturnal with the steps below: Now you can add the RSSI as an individual sheet during live recordings and when reviewing PSG data within Noxturnal as shown in the picture below. ndb file into Noxturnal using the Import settings ( Tools - Import/Export Settings.). You can download a Noxturnal Sheet with the RSSI Signal already prepared as an attachment below this support article. Its ability to provide a rough estimate of signal strength and distance can help improve the reliability and performance of systems that utilize wireless transmission.Īdding the RSSI Signal to Noxturnal Importing a pre-configured signal sheet: The reference level can vary depending on the system and the type of signal being measured. RSSI is typically measured in decibels (dB), and is normally reported as a negative value, indicating the strength of the received signal relative to a reference level. It is commonly used in wireless communication systems, such as Bluetooth, to estimate the distance between the transmitter and receiver, as well as to determine the quality of the received signal. Received Signal Strength Indicator (RSSI) is a measurement of the power present in a received radio signal. Received Signal Strength Indicator (RSSI)
This feature requires Nox A1s firmware 3.0.6 or greater. Aim for an RSSI between -40dB and -60dB range to reduce issues with Bluetooth transmission, and use the tool to determine if the connection between the Nox A1s and Nox C1 is the cause of any issues during an Online Recording. Users can download a Noxturnal Sheet with the RSSI Signal already prepared, or create their own RSSI sheet. a/drivers/net/wireless/realtek/rtw89/rtw8852a.Noxturnal now features a Received Signal Strength Indicator (RSSI) signal that allows users to check the quality of the Bluetooth® connection between the Nox A1s and Nox C1 during an online recording.
