how to free memory from calling Bangle.buzz ?

Hi,

in my game when i call Bangle.buzz free memory keeps decreasing until it runs out of memory. I noticed in the documentation it says it returns a promise but i'm not familiar with them and i don't know how i should use Bangle.buzz so it does not keep eating free memoy or how to free the memory from probably the returned promise.

for example when testing i tried this code and it runs out of memory when doing this resulting in an error:

var memStart;
  memStart = process.memory(true);

for(i = 0; i < 1000; i++)
{
  Bangle.buzz(1,1);
  
var memTmp = process.memory(true);
var used = memTmp.usage - memStart.usage;
  print(i.toString() + ": Udiff:"+ used.toString() + " used:" + memTmp.usage.toString() + " free:" + memTmp.free.toString() + " total:" + memTmp.total.toString()  );
}

for(i = 0; i < 1000; i++)
{
   Bangle.buzz(1,1);
var memTmp = process.memory(true);
var used = memTmp.usage - memStart.usage;
  print(i.toString() + ": Udiff:"+ used.toString() + " used:" + memTmp.usage.toString() + " free:" + memTmp.free.toString() + " total:" + memTmp.total.toString()  );
}

for(i = 0; i < 1000; i++)
{
  Bangle.buzz(1,1);
var memTmp = process.memory(true);
var used = memTmp.usage - memStart.usage;
  print(i.toString() + ": Udiff:"+ used.toString() + " used:" + memTmp.usage.toString() + " free:" + memTmp.free.toString() + " total:" + memTmp.total.toString()  );
}

I'm not sure if i'm doing something wrong here but it shows something like this as a result
