Frontend. Passive mode Cost was the main requirement for the solution. Static web site is used to provide placeholder during off Net hours since it doesn’t have any purpose other than handling the Net. Amazon S3 static web site allows to handle any amount of traffic and provide millisecond replies for static data. It also makes convenient to handle switchover between active and passive solutions using AWS native toolset.
One of the downsides is that S3 hosted website can only handle http traffic.

The idea of the project is to provide the ability to place your Nextion display and hotspot in different locations in your house. Since UART (Universal Asynchronous Receiver/Transmitter) protocol is used for communication between the hotspot and display, it becomes easier to experiment with all kinds of options.
There are many controllers available today with UART interface onboard. Some of them can even emulate virtual COM ports when they are connected via USB.

Here is my approach to using talkgroups and my AnyTone radio on BrandMeister, as well as using the BrandMeister SelfCare account to check the status of static and auto-static talkgroups right in the browser. There’s also some commands that can be used in any Linux Terminal, and they also should work in Windows Subsystem for Linux or even a router shell.
