I am new to lejos and java at all. This fall I bought an EV3 and additional sensors and parts. I am working on my first 2 projects for less than 2 month now. It really was fun to get into this by now, everything went fine so far, until this weekend. I took my EV3 with me to a friend to demonstrate the 2 projects. A graphic sensor monitor showing a graph with sensor values and a simple ir remote controlled drive program. Both ran without any problems at home, but this time, there was some kind of infrared sensor issue. The programs did both not react properly to the infrared sensor input and the whole execution stuttered at all. Best example was my graphic sensor monitor. As soon as the infrared sensor was initiated, the program began to hang for a few seconds and then ran properly for another few seconds and then hung again and so on. From time to time the sensor values were shown correctly, rest of the time not. It seemed like I would break the connection to the sensor every few seconds.
At home I started to investigate the problem. Once connected via bluetooth networking to my pc with EV3 control from the ev3tools running and connected, both programs again functioned properly. After disconnecting from the pc the issues were back. I have exchanged cables, with no result, the issue is still there. I will investigate further as soon as I find the time and also would like to post the graphic sensor monitor in EV3 projects, as soon as it is fixed.
Perhaps anyone knows about this issue and how to fix it ? I would appreciate any help.
