It seems to me there may be missing dependencies during the installation Netbeast node palette or an API error in the node palette's NodeJSNodeJS code. The Author of the Netbeast node can only tell us more about this. But I don't think this issue is from Node-RED

techielew•3/3/24, 9:59 PM

Hmmm, tough one. @abhishek awasthi?

There was another question recently about distributed systems architectures. There's a company who doesn't do Linux per se but has a companion RTOS to Windows/Linux hosts that is capable of managing distributed applications. I know this isn't what you're looking for but perhaps some of the documentation on page 4 here can give you a conceptual idea: https://tenasys.com/wp-content/uploads/2023/09/TenAsys.DS_.RTOS_.v3.92123.pdf

Yyoucef_ali What are #LVDS Low voltage Differential signals and use cases ?

aymen ammari•3/4/24, 11:12 AM

Low Voltage Differential Signaling (LVDS) is a method for transmitting digital data at high speeds over twisted-pair copper cables. LVDS uses differential signaling, meaning it sends the same signal over two wires with opposite polarities. This helps reduce noise and increase the immunity to electromagnetic interference.

LVDS is commonly used in various applications, including:

1. High-Speed Data Transmission: LVDS is widely used in applications requiring high-speed data transfer, such as displays, monitors, and high-speed serial communication links.
2. Display Interfaces: LVDS is often used in flat-panel displays, such as LCD and OLED screens, to transmit video data from the graphics controller to the display panel.
3. Automotive Applications: LVDS is employed in automotive systems for transmitting video signals between components such as cameras, displays, and infotainment systems.
4. Industrial Applications: LVDS is utilized in industrial automation systems, where high-speed, reliable data transmission is essential for control and monitoring purposes.
5. Networking Equipment: LVDS can be found in networking equipment, such as routers and switches, for transmitting data between different network components.

Overall, LVDS offers high-speed, low-power, and reliable data transmission, making it suitable for a wide range of applications where high-speed digital communication is required.

No worries, I'm not expert as signals but here is what I found in the Net :

aymen ammari•3/4/24, 1:04 PM

The best way to receive LVDS signals depends on the specific requirements of your application and the capabilities of the receiving device. However, here are some general guidelines for receiving and managing LVDS signals:

1. Use Proper LVDS Receiver ICs: Choose LVDS receiver ICs that are suitable for your application and meet the required speed, voltage levels, and noise immunity. There are many LVDS receiver ICs available from various semiconductor manufacturers designed specifically for different applications.
2. Match Impedances: Ensure that the impedance of the transmission lines and the receiver inputs match to minimize signal reflections and maintain signal integrity. This typically involves using controlled impedance transmission lines and termination resistors at the receiver end.
3. Clock and Data Recovery (CDR): In high-speed applications, consider using a Clock and Data Recovery (CDR) circuitry to recover the clock signal and data from the incoming LVDS signals. This helps to ensure accurate data reception even in the presence of jitter and signal distortion.
4. Signal Conditioning: Depending on the specific requirements of your application and the characteristics of the LVDS signals, you may need to implement signal conditioning techniques such as equalization, pre-emphasis, or filtering to improve signal quality and reliability.
5. Power Supply Decoupling: Properly decouple the power supplies of the LVDS receiver ICs to minimize noise and interference. Use low-noise power supplies and bypass capacitors close to the ICs to filter out high-frequency noise.
6. Grounding: Pay attention to grounding techniques to minimize ground loops and reduce noise coupling into the LVDS signals. Ensure a solid and low-impedance ground connection for both the transmitter and receiver sides.

aymen ammari•3/4/24, 1:04 PM

7. Error Detection and Correction: Implement error detection and correction mechanisms if necessary, especially in applications where data integrity is critical. This may involve using techniques such as CRC (Cyclic Redundancy Check) or FEC (Forward Error Correction).

InsightMike•3/4/24, 2:37 PM

You shouldn't have any compatibility issues. Most important is selecting the right frequency for your region. If your gateway is just used as a "packet forwarder" for low volume traffic, any will work fine. If you need to embed your LoRaWAN Network Server on the gateway then you'll need a higher end product. Also, some gateways have better range performance and better high traffic performance, but if you're just doing some small system testing that won't be an issue.
