Hi,
I’m working on a project where I want to display information from my Arduino Uno (connected to my car) and send data through a BLE module (Adafruit nRF8001 BLE Breakout Module). With this, I downloaded the libraries provided on Blynk’s website and was unable to get simple examples to compile. I have some good experience with how to add libraries to the Arduino IDE, but I can’t seem to figure this out. Any help or suggestions? Can someone provide the…
BlynkSimpleSerialBLE.h
BLEPeripheral.h
BLESerial.h
hal_platform.h
libraries separate from the downloadable file provided on Blynk’s website? Thanks.
Here’s what I’ve downloaded…
Still no luck. I began by reading the instructions at the top of the sketch. I’ve compiled the Adafruit Bluefruit LE example and manually added each library that populates in the error messenger of the Arduino IDE. I also attempted to use the library manger to install the libraries. I even deleted everything and restarted just in case there was a bug…Wish there was a downloadable file of only Adafruit Bluefruit LE libraries, so the basic example programs were more user friendly.

Sketch uses 21,854 bytes (67%) of program storage space. Maximum is 32,256 bytes.
Global variables use 1,757 bytes (85%) of dynamic memory, leaving 291 bytes for local variables. Maximum is 2,048 bytes.
Low memory available, stability problems may occur.
***Removing #include SPI.h cured the issue displayed above. Why is this? What can be changed to allow #include SPI.h to be added to my BLE Sketch? Lastly, why so much storage used!?! (Sketch uses 21,854 bytes (67%) of program storage space. Maximum is 32,256 bytes.
