Dear forum members,
As the number of home network devices increases, I become more and more concerned about the security of my home network. From smart TVs and smart refrigerators to home security monitoring systems, it seems like every device can be a potential security vulnerability. I want...
Hello! everyone
Has anyone tried to implement real-time data transmission in the LoRa module?
Can you share some implementation process and experience?
I've recently been trying to implement real-time data transmission in a LoRa module, but I've encountered some challenges. Is there any...
Hello community members,
I am currently developing a wireless charging solution for ultra-low power IoT devices, which are mainly used for health monitoring and environmental sensing. To maximize device uptime and reduce maintenance requirements, wireless charging technology is being considered...
NB-IoT (Narrowband Internet of Things) is ideal for alarm detectors and security systems. NB-IoT is a low-power, long-distance, narrow-bandwidth IoT communication technology with the following characteristics, making it suitable for alarm detectors:
Low power consumption: The low power...
The real-time requirements of embedded systems are one of the key factors for their successful operation. Real-time requirements involve ensuring that the system can respond and perform tasks within a predetermined time. This article will discuss how to deal with the real-time requirements of...
Hello everyone,
I'm facing an interesting challenge and would like some advice on WiFi connections. In my house, there is a router and I need to transmit the WiFi signal to a place about 100 meters away from the house, where there is a solar farm with a photovoltaic inverter that requires WiFi...
Hello everyone,
I'm working on an IoT project where I need to connect multiple devices to a LoRa network. Although I have some knowledge about LoRa technology, I am still a little confused when it comes to handling multi-device communication. I want to be able to connect sensors, controllers...
In Android 10 and above, there are some system and app-level optimizations and policies that may cause WiFi or Bluetooth scanning to remain on after these features are turned off. The following are possible reasons:
System optimization: Some versions of Android will automatically reopen these...
Hello everyone!
Recently I was looking for a cost-effective bluetooth module for my DIY projects. After some searching and comparing, I found some lower priced bluetooth module options, but before choosing, I would like to know if anyone has similar experience with it, or is there any...
The mystery behind wireless calls on mobile phones： How do built-in antennas enable communication?
Hello everyone!
As an indispensable tool in our daily life, the wireless calling of mobile phones allows us to keep in touch with friends and family anytime, anywhere. But, can someone explain in...
Capture the Signals:
Ensure you have access to the three digital signals in your Simetrix simulation. You'll need the waveform data for each signal.
Identify a Reference Signal:
Choose one of the three signals as your reference signal. This will be the baseline against which you'll measure the...
Hello everyone
I plan to use ESP8266 WiFi module for a stable connection project. Before starting, I want to sort out some technical issues about this WiFi module to ensure that I can configure and use it correctly to obtain stable connection performance. Here are some of my concerns...
The following measures can be considered:
Use advanced modulation: Using higher order modulation (such as 1024 QAM) can transmit more data in the same frequency bandwidth, but also makes the signal more sensitive to noise and interference. Make sure your system can maintain sufficient...
E32 (433T20S1) needs to design a SMA head. Connect a 5CM long glue stick antenna. The antenna is parallel to the module and 3 cm above the module. Will it interfere with itself when transmitting? How to solve it?
