Processor Boards • Trouble getting started with SparkFun Blues Wireless MicroMod Starter Kit -STM32F405 no serial port?

Hello!

This is my first time working with low level hardware. Please forgive my ignorance

I recently picked up a SparkFun Blues Wireless MicroMod Starter Kit. I've been attempting to complete the tutorial on Blues' website, but haven't succeeded.

When I plug my USB cable into the main board - no COM port is shown in Device Manager (Windows 10). If I put it into DFU mode by holding boot + tapping reset then I see "STM 32 BOOTLOADER" shown in Universal Seris Bus devices. So, I believe my cable works OK and my computer can see the device, but it does not see it as being able to communicate.

I can upload sketches to it through the Arduino IDE and don't get any errors, but the code doesn't seem to run as far as I can tell. Here's the output I get when I upload some basic example code:

```

I looked into drivers for it but the latest explicitly shipped drivers were for Win7/Win8. There's a note in the README that says:

```
* V1.5.0 - 02/05/2018
=====================

New Features
************
+ Install simplified for better user experience depending on Windows OS,
+ For Windows 10, use Microsoft inbox driver and not this package.
```

which I think means that it should be plug-and-play in Windows 10.


https://community.st.com/t5/stm32-mcus- ... d-p/437577 this person describes a similar issue, but their resolution was soldering?? It's unclear if that's my issue and that's too extreme of a step for me getting my hands dirty.

It's not clear to me if I'm wildly off base somewhere. I am able to get a COM port when I plug a USB into my Notecarrier Function Board but when I query the state of the function board it's not updated to reflect the commands that should've been sent by the firmware I uploaded to the processor.

For clarity, here's the code I'm uploading:

```
#include <Notecard.h>
#define productUID "com.gmail.Meo.DDR:feed_connect"
#define usbSerial Serial

Notecard notecard;

void setup() {
delay(2500);

// put your setup code here, to run once:
usbSerial.begin(115200);

notecard.begin();
notecard.setDebugOutputStream(usbSerial);

J *req = notecard.newRequest("hub.set");
JAddStringToObject(req, "product", productUID);
JAddStringToObject(req, "mode", "continuous");
notecard.sendRequest(req);
}

void loop() {
// put your main code here, to run repeatedly:
}
```
After I upload this, I tap reset on my main board, wait, and then un `{"req":"hub.get"}` but I see my mode is still in "periodic" not set to "continuous"

Thanks for your time
