No such memory, or...?

on my f3discovery i write:

function delays(s){var n=1000; while(n--){}}

spi = new SPI();

spi.setup({sck:A5, miso:A6, mosi:A7});
var nrf = require("NRF24L01P").connect( spi, B0, B1 );
function onInit() {
  nrf.init([0,0,0,0,2], [0,0,0,0,1]);
}

onInit();

setInterval(function() {
  nrf.masterHandler();
}, 50);
function g1on(){digitalWrite(B9,1);}
function g1of(){digitalWrite(B9,0);}

//function a1on(){digitalWrite(B8,1);}

it works ok, but if I try to add the last (commented) line it doesnt work -
download process doesn't finish properly. - no "=undefined" string.
process.memory() shows nothing criminal -

>process.memory()

what can be? thanks!

What do you mean by doesn't finish properly? What happens when you type a1on()?

Also, if you type dump(), what gets shown? Is the function listed?

I cant type It. it doesn't allow type anyth.
But I fixed it already by setting .js|.min.js in minification setup.
dump() lists the functions - it's ok there.
Ough! Update -
It helped only for 3 added functions. And appeared again when i try to add more than 3.

Under IDE settings, under communication, enable throttling - I see this sort of behavior fairly often on the official board if I don't enable throttling.

Shame... I thought the lost character issues were mostly fixed on newer firmware versions.

To get control back, you can usually do Ctrl + C then echo(1); then enter.

thanks, CTRL-C + echo(1) returns control, but program doesn't work.
But everything is ok after moving the reqired module code to the right pane.

The lost character issue has gotten better, but I've found that often the code reaches a point where it starts intermittently losing characters.

Could you e-mail me something that exhibits the problem? It'd be goog to look into it and see if there was anything I could do...
