Problem with "nxj -b"

[carath63]

I am running into a problem trying to upload programs to my NXT over the bluetooth connection with "-b" option on the nxj command line.

Whenever I run nxj -b, I get logging messages that indicate the NXT was found, but then I get an IllegalArgumentException: invalid param [encncrypt=false]

I am guessing that encncrypt is a typo for "encrypt", but I'm not sure where this parameter is being set.

Has anyone else run into this?

BTW: I am running lejos 0.3 with the 2.0.0 Bluecove jar.

I downloaded the source code for NXTCommBluecove and found the open() method. It is setting up the resource string to:

"btspp://" + NXT-DEVICE-ADDRESS + ":1;authenticate=false;encncrypt=false"

I also found the code for MicroeditionConnection.openImpl() where the exception is being thrown. The parameter it is looking for is named "encrypt", not "encncrypt";

Hi Christopher,

I've never had any problems like this so it's strange you are having a problem. Which operating system/Bluetooth dongle are you using?

Is it maybe a Toshiba computer?

I am running Windows XP Professional, Service Pack 2. I have the Abe bluetooth dongle that I ordered from the Lego shop. I have an IBM thinkpad T43.

Is it possible I have an old version of the NXTCommBluecove class? The bluecove jar file I picked up was 2.0. I don't know what version of the source code I was looking at when I saw the "encncrypt=" string.

I'll try downloading the 0.4 version of lejos and see if that clears up the problem.

After downloading and installing the 0.4 version of lejos, I was able to successfully upload the Tune program to my NXT using the bluetooth connection.

I'll start playing around with the new version and try things out. This certainly makes the upload process a lot easier.
