How do I control the onboard LEDs of my Arduino Nano 33 BLE Sense?

There are 3 LEDS on the Nano 33 BLE: A power LED on pin 25 (yes, you can turn off the power LED programmatically); A built-in LED on pin 13; An RGB LED with red on pin 22, green on pin 23, and blue ...

Arduino nano 33 BLE serial port not working with C# app

I noticed that a lot of line discipline and flow control settings were not made explicit in your C# code, so it made me wonder what they were by default. In particular DtrEnable appears to be false by ...

Arduino Nano 33 battery power/charging

The VIN (and the USB) goes into a 3.3V switching regulator. This has a minimum input voltage of 4.5V. You isolate the output of that regulator from the rest of the circuit by cutting that one link (...

Copying String into another String

Do not work with the String class on Arduino. That said what to do? Use char arrays (what an individual String is internally). Then you work with pointers or pointers to pointers. Guessing from the ...

Arduino Nano 33 BLE - use of flash to store data; how to expand a piece of sample code

I guess a simple solution would be to stick with the original pattern and use only one variable... but have this variable be a container for all the stuff you need: struct StoredData { int32_t ...

Arduino Nano 33 BLE - use of flash to store data; how to expand a piece of sample code

You can also try my FS_Nano33BLE Library with simple-to-use LittleFS / FATFS. The filesystem access uses normal POSIX APIs or mbed FileSystem APIs

Arduino Nano 33 BLE - use of flash to store data; how to expand a piece of sample code

I can't really help with the source code you found, but here is a simpler solution for your original problem: I wrote a library called NanoBLEFlashPrefs. It allows you to store parameters and ...

Nano 33 BLE Sense powered with Vin and USB at the same time

In this power block you can see there is only one Schottky diode with the voltage drop under 0.5V@2A. That means D2 is closed around the condition: VUSB < VIN. On the other side if you add 3.6-4.2V ...

Arduino 5v pin outputting lower power than expected

Well, I thought by now someone else would have answered it. But, I'll try. I'm not familiar with this chip and board, so what I can tell you is pretty limited. In short, you have a 3.3V micro-...

Arduino nano BLE sense Serial port Suddenly stopped working

All that has happened is that you don't have a sketch running. When you have a board with a native USB connection a sketch has to be running to make that USB connection be anything. You corrupted your ...

Is it possible to extract the firmware of an Arduino BLE or IoT board wirelessly?

Technically, the firmware can read its own application section, but it won't send it to you wirelessly (or via any interface) if such a feature isn't implemented in that firmware. If you were to ...
