ESP8266, BearSLL and setBufferSizes


following this article

I tried to save momery with Fragment Length Negotiation (see chapter "MFLN or Maximum Fragment Length Negotiation (Saving RAM)")

unfortunately my servers does not support MFLN, so the probeMaxFragmentLength always returns false

BTW, i noticed that I can still call

espClient.setBufferSizes(1024, 1024);

even if probeMaxFragmentLength returns false

and it works!

printing the free HEAP, it save a lot of memory and everithing works

Does anybody know what is the risk in calling setBufferSizes even if the probeMaxFragmentLength returns false?
