Another quick update. The tool is basicly done at this point, and I expect to toss the source online on thursday. Another member of my study group have the NXT at the moment, and I just want to perform a quick check for stupid bugs before releasing it. It is now possible to zoom around in the captur...

A quick progress update. I'm pretty close to being finished with the feature set I plan for my own use. Left to do is the posibility of scrolling in the data after logging have ended, some sort of export, as well as changing to use circular buffers, so that the program doesnt slow down when you run ...

Just to confirm. I ran into this issue again today, and I had of course forgotten all about it, so took an hour to track the issue down inside my logging tool. The setup was, with non-related details remove: public abstract class BaseChannel{ protected DataOutputStream nxtOut; public BaseChanne...

A quick update. I've restructured the code on the nxt-side to get around the constant pool limit, and ive implemented the ability for the client side code to signal additional meta-data about each channel. The initialization code //Establish remote log connection RemoteLog log = RemoteLog.waitForCon...

Bluetooth data logging and debug on the nxt

Hi I've been working on a tool that makes it possible for my leJOS programs to report sensor readings and other values back to a computer in real time. The system is based on the notion of channels, which you create a number of as your nxt program starts up. A channel allows you to sample specific t...

Thanks for both answers. I've made what basicly amount to a BufferedOutputStream on the nxt, and patched the BTOutputStream with a byte array write method that only kicks in when the len < 254. Will try to modify NXTCommBluecove as suggested.

Size limit on bluetooth packets

Hi Im fooling around with some nxt->pc communication in order to get a grip on the concepts. My goal is to use bluetooth to send some sensor readings and such back to a pc for a high level action planning. I can see that the current implementation sends each byte in a seperate BT packet, which gives...
