https://devzone.nordicsemi.com/f/nordic-q-a/30175/how-to-get-the-free-ram-during-rumtimeHello, How can I detect how much RAM is still free on the heap during runtime, without a debugger attached, just from within the application?

If you use head and need to keep track of the available size, you could store the heap size in a variable and decrement/increment it when you call malloc/free to keep track of the used size.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
