This is a limit to to save memory, it can be tuned here https://github.com/espruino/Espruino/blob/master/boards/BANGLEJS2.py#L48
and beware that it also needs tuning next line with matching LD_APP_RAM_BASE otherwise it won't start and just reboot in a loop.
Note that it may also break other stuff inside Espruino and may need further tuning, even with 130 there were some overflow issues as it was 'too fast'.
OTOH even 130 is pretty high and you will have this limit anyway so maybe better solution is to handle lower MTU too.
