problem with manual node_id

[abrasha]

i wanted to assign manual node id to every sensor in order to have a list that will track nodes location and task along my project.
so for my repeater i changed to:
gw.begin(NULL, 1, true)
1 is for example of course.
and for a binary-senosr sketch i changed
gw.begin()
to
gw.begin(NULL, 3);

now, the repeater node works fine, even with a great distance from the controller - through 1 or 2 repeaters on the way.
but the binars-switch connects only when it is close to the controller but not through repeaters. another strange thing is that the nrf (+pa +lna +sma antennna) gets warm after some time.

is there someting wrong with the code? thats the only thing ive changed.

setup: rpi2 with domoticz and serial gateway.
boards - sparkfun redboard

ok i think its solved. well sort of...
i tried clearing the eeprom of the board and uploading again ( with (NULL , 3) modification) but still i didnt get any siganl on domoticz and again the radio started getting hot.
so switched to another board (chinese NANO) with original sketch with gw.begin() and it worked.
i dont know if its the board replacment or the sketch replacement that did the trick but for now its working.
