memory of arduino nano ble

Question

Our memory of the arduino is full, so we cannnot upload the sketch anymore, but we dont have finished all of the code yet. How can we fix that?

Answer 1

Reduce the size of the sketch, eg. by removing code, use tips given here, remove large libraries (replace with smaller/more efficient ones), use the F() macro:

Replace code like:

Serial.print("Hello world");

With:

Serial.print(F("Hello world"));
