Hello, I have a hall effect sensor v2 which has a baseline signal around -350mT. It reacts ok to the presence of a magnet (north and south), but gives a non zero signal when nothing is around. It gives the same signal (and same polarity) when I move it around and I flip it, so it is not reacting to an ambiant magnetic field. It looks like it is itself magnetized and detects its own magnetic field. I tried a few other hall effect sensors, one is giving 0 as a baseline, another has something like -300mT. Is there somehting that can be done to recalibrate the sensor? Should I request a replacement for defective items? Thank you for your help.

Hello I have a problem when I disconnect and reconnect a Hall Effect Bricklet 2.0. After reconnecting, the bricklet is no longer accessible in Brick Viewer (not working in my own program neither). It is detected but when I go to the bricklet tab, I have this message "This bricklet is in booloader mode". This happens whether I disconnect the master brick USB or the 7-poles cable at the master brick side. The only way I found to get the bricklet back is to disconnect and reconnect the 7-poles cable at the bricklet side. This is not practical in my application since the bricklet is not accessible (requires substancial work to reach it) so I would need a more convenient fix for this problem. Ideally, the bricklet should still be funcitonnal after disconnecting and reconnecting the USB. If it is stuck in bootloader mode, there should be a way to reinitialize it without having to phyisically reach the bricklet connector. Is this problem a hardware issue with the bricklet I have? Or is it a repeatable problem? If so, do you have a suggestion for me to try? (hardware or software). Thank you for your help Arth
