Create a wifi configuration for Pi0 W that works

Hello, following examples, I created a wpa_supplicant.conf file directly on the SD card with the settings of my wifi network by connecting it to my PC. But it doesn't work. Apparently, upon restarting Pi and checking the boot folder, my file is not visible. Could this be the reason for the non-functioning? How can I remedy this problem?...

No WIFI connection with my ESP8266.

Hi all, I don't understand why, but my ESP8266 no longer wants to connect to the WIFI. The name of my network and my password have been verified. I tried with another shared network from my phone. I did a reset of the ESP8266 with nodemcu-flasher-master. Here's my simplest code...

TCP over Matter/Thread

Any body tried TCP over thread wireless network? I know Thread latency will make TCP complicated, but it would allow to punch home gateway and CGNAT with a keep-alive of 10ich minutes in place of 30sec we need to use over UDP. I'm curious to know if someone tried and tweaked the server TCP stack (RTO, F-RTO..)

Wireless Communication Between Arduino Boards

I have multiple Arduino boards in my project, and I need them to communicate wirelessly. I've considered using RF modules, but I'm unsure about the most reliable and efficient way to establish communication between the boards. Can anyone share best practices or example code for establishing wireless communication between Arduino boards? Thank you!

Unable to Connect to HC-05 Bluetooth Module via Mobile App

I have created an Android App using MIT App Inventor. And have connected the HC-05 Bluetooth Module to Arduino over Serial UART communication. When I paired the HC-05 module, it got paired with a mobile phone. But then when I try to connect the same module on the same mobile though custom-built Android App HC-05 doesn't show up to connect. I wonder if someone has faced a similar issue. Appreciate any help you can provide Thanks in advance!...

Entitlement server and Discovery server in eSIM

I am new to eSIM technology. I have gone through some online articles on the architecture, which states, discovery server informs user of eSIM profile availability in SMDP+ and accordingly user can download it: https://www.gsma.com/esim/ "The ubiquitous SIM card has played a fundamental role in mobile telecommunications for over 25 years. It is recognised by end users and provides a secure means for authenticating devices onto networks, all inside a removable “Secure Element”, which..." But is it not the same as what entitlement server does? Can someone also explain what is the role of Entitlement server in eSIM. If possible please also explain the position of ES and DS in eSIM architecture....

IP Address issue: No IPv4 with the latest Raspberry Pi OS

Recently, I have installed the latest Raspberry Pi OS on Raspberry Pi4. When wifi configured, and trying to get the IP address (IPv4). Surprisingly found that I could only get the IPv6 address which looks like xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx. Since I need an IPv4 address something like 192.168.xxx.1. Since using IPv6 is not convenient to use for SSH The same RPi4 when used at the office with another laptop, I can able to get an IPv4 address. I appreciate it if someone could suggest the best network settings. So that I can get IPv4 quickly whenever I ping RPi through the command prompt using 
ping raspberrypi.local
ping raspberrypi.local
As far as I know, RPi default acquires an IPv4 address when connected over DHCP. Appreciate more information on this issue or changes in new Raspberry Pi OS ...

README: Edge Networking Forum

Forums are designed to help DevHeads community members come to quick resolution on a variety of systems integration topics. These differ from the ⁠#seeking-collabs (find a professional dev who can help build your project) and ⁠#projects-and-self-promotion (show off your design accomplishments) sections. The #edge-networking forum facilitates information exchange around the electronic hardware disciplines listed below, expressed in tags. DevHeads is a professional engineering community, but if you're just getting started in a field use the "Getting started" tag. When creating or searching for a post, we recommend using multiple tags to make it easier for other devs to navigate and find specific topics. These tags are visible in the upper left of each #edge-networking post: ...
