Not sure what you are asking? I have used NFS for all sorts of things for the last two decades. But specifically, I am quite sure there is no 32kb limit with Hanewin NFS used with Kodi, either to or from.
Addons I wrote &/or maintain:
OzWeather (Australian BOM weather) | Check Previous Episode | Playback Resumer | Unpause Jumpback | XSqueezeDisplay | (Legacy - XSqueeze & XZen)
Sorry, no help w/out a *full debug log*.
