The tech market is experiencing a shift in customer demand, moving away from physical devices toward digital-only options.

[sys1]
Customer demand has shifted from physical devices to digital-only options.
We need to understand why this change is happening and find strategies to address it.
Key factors may include cost, convenience, and technological trends.
[end sys1]

[sys2]
**2.1 Understand the Problem:**
The goal is to understand the underlying reasons for the shift in demand from physical devices to digital-only options, then develop a strategy to adapt.

*Reflection:* 
"I understand that preferences are changing, but what might be driving this? Is it primarily cost, or are there other factors such as convenience or sustainability?"

*Creative Perspective:* 
"Could there be a larger trend in digital minimalism or a preference for eco-friendly solutions that we’re missing? What unseen motivations might explain this shift?"

**2.2 Analyze the Information:**
There are multiple possible factors driving this shift, from economic influences to cultural shifts. It’s essential to isolate each factor and understand its impact.

*Reflection:* 
"Am I fully considering the various economic and social influences? Could there be a technological factor, like better internet speeds, that makes digital-only products more accessible?"

*Creative Perspective:* 
"Are there patterns or trends in other markets that could shed light on this shift? Could this be part of a larger trend toward virtual experiences?"

**2.3 Generate Hypotheses:**
1. Customers prefer digital options due to lower costs. (Confidence: 0.8, Creative: 0.4)
2. There’s a growing trend toward minimalism and reduced physical clutter. (Confidence: 0.7, Creative: 0.7)
3. Digital products offer greater flexibility and ease of use. (Confidence: 0.6, Creative: 0.6)
4. Environmental concerns are pushing consumers away from physical goods. (Confidence: 0.6, Creative: 0.8)
5. Advances in tech make digital-only options more functional. (Confidence: 0.8, Creative: 0.5)
6. Pandemic-era remote work increased demand for digital solutions. (Confidence: 0.7, Creative: 0.6)

Q:

UART Communication Between STM32F03 and ESP-8266-01

I'm attempting to get a smartphone app to communicate with an MCU (STM32F030R8). The step I'm currently on is getting the WiFi module to talk with the MCU. I'm able use the AT firmware to configure the ESP when using an Arduino Uno/PC terminal, but want to essentially do the same via the STM board. 
When I load the code to the STM and use Tera Term to send data to the STM it should be able to send AT commands to the ESP, but it isn't working. Right now I'm at a loss as to why this isn't working. I'm looking for pointers on the code that I've probably missed or other principles I've overlooked/am unaware of. 
I've searched around on the internet the past couple days and haven't come up with much that helps. This is effectively the sum of my experience with C. Thanks for your help!
The hardware is set up as follows...
STM32     ESP
PA10      TX
PA9       RX
3.3V      VCC
3.3V      CH_PD
GND       GND

UNO       ESP
TX        TX
RX        RX
3.3V      VCC
3.3V      CH_PD
GND       GND

The code I've frankenstein'd together is below. I'm using Keil uVision 5.

I've modified the code a bit and kept trying. When attempting to change the broadcasted network name/password (it didn't work) it now replies with the first two typed characters in the command consistently and after a moment put forth the gibberish at looks like it should have been summoned with an "AT+GMR" command. The following code is what was uploaded to the device. Any thoughts on how this could have happened? Thanks!

A:

I was able to get the ESP to respond to the AT commands with the following code. There are sections commented out as I was simply frankensteining my way to 'working' code. I was able to change the SSID and password via a hard coded string. I simply sent it by pressing 'Enter' to get the code to proceed. 
As it turns out the issue laid in sending data to the ESP (rather than receiving, which was my initial theory). Now I need to get the code to receive an uint8_t[] from the terminal, but that is a separate issue from the original question so I'll mark this as answered.
