Hi, I think that the problem resides in the HAT, but is erratic. My HAT is mounted on top of an raspi PI 4. HAT's configuration is like out of the box, I never changed anything. Firmware Version is 2.0.3. Raspi ist powered with an original Raspi power supply, HAT says 5.17Volt. On the HAT is connected: 1 Compass Bricklet 1 DC Bricklet 2.0 1 Hall Effect Bricklet 2.0 All Bricklets have the latest Firmware. All LED's are shining, NOT blinking. In the BrickViewer I pressed the "Sleep Now" Button on the HAT Brick Tab . After a few seconds the Hall Bricklet began blinking very hectical - not like hartbeat. but the other Bricklets not! They continue shining. The compass Bricklet works fine as before, but the Hall Bricklet Tab shows an "Flash" button. After the error I started my Java App, an this Exception was presented: Exception in thread "main" com.tinkerforge.TimeoutException: Did not receive response in time for function ID -1 at com.tinkerforge.DeviceBase.sendRequest(DeviceBase.java:225) at com.tinkerforge.DeviceBase.checkValidity(DeviceBase.java:175) at com.tinkerforge.BrickletCompass.setHeadingCallbackConfiguration(BrickletCompass.java:292) The Compass ist the first one that I connect. I tried this a few times again, but unfortunately the problem did not occur anymore. IMHO changes the HAT erratic into sleep mode, but why - I don't know. Hope this helps. Best Regards RBBT

Hi, I have the same problem with this Bricklet. It worked over a few hours without any problems. But today I come into the same troubles as arthurPV. I haven't started any firmware flashing or else. The Bricklet isn't damaged in any way (shortening a circuit or similar...). Removing the cable did not help. But removing from the magnet helps. My Bricklet is very close to a magnet before I startup. Do you have any solutions for this problem? Thanks in advance RBBT
