• Well with espruino long writes doesn't work too, it is just that these features are confusingly similar so that it is not clear which one is used.

    Supporting long writes in espruino may be easier as the buffer may be allocated dynamically from variable space when asked for (explained here) while bigger MTU probably needs firmware with this enlarged buffer compiled in.

    However unlike long/prepared/buffered writes, bigger MTU give real improvement in speed so is probably nicer thing to have.
