How to send / access an variable (long [][]) to / from PC?

[Sonny1982]

He guys, I have a NXT remote car which is controlled by another NXT. The car saves data in an 2 dimensional arry which is [100][3]. Now, if the array is fully loaded, I want to close the connection from the car to the remote and open a connection to the PC. No problem so far. But how can I access or send the array from the car to the PC now?

Hope someone could help me?

Regards

Can't you just use a dataOutputStream and loop through it

for(...x...){
for (...y...){
writeLong(carData[x][y]);
}
}

Then on the pc, would do the opposite and read it in.

This assumes your array is really full. If not then you'd have to work out a scheme to tell the pc how much data to read it.

EX

write x.length
for (...x...){
write y . length
for (..y..) {
write carData[x][y]

then for your data on the pc side, read data in according to the x.length and y.length values that you sent from the nxt
