See the thread Brick Daemon 2.4.6 not working for a discussion of the problem instructions for downgrading to brickd 2.4.5 (fix) a preview of brickd 2.4.7 (alternate fix)

It works here.

@zbindenp That is exactly what I did. Thanks for sharing the write up. This would be an excellent opportunity for reviving the near-dead blog. Write two lines informing us about the (avoidable) problem and the fix. RSS is our friend.

Hello, I have upgraded four of our systems from brickd 2.4.5 -> 2.4.6, and brickd stopped responding on all of them: <I> <main_linux.c:385> Brick Daemon 2.4.6 started (architecture: arm, pid: 25228, daemonized: 1) <I> <main_linux.c:391> Running on Linux system (sysname: Linux, release: 6.1.21-v7+, version: #1642 SMP Mon Apr 3 17:20:52 BST 2023, machine: armv7l) <I> <bricklet.c:274> Found supported HAT product_id 0x084e in device tree, using default HAT Brick config <I> <bricklet.c:315> Found Bricklet port A (spidev: /dev/spidev0.0, driver: gpio, name: GPIO23, num: 23) <I> <bricklet_stack_linux.c:87> Using spidev backend for Bricklets, because Raspberry Pi without BCM2835 detected <I> <bricklet.c:315> Found Bricklet port B (spidev: /dev/spidev0.0, driver: gpio, name: GPIO22, num: 22) <I> <bricklet.c:315> Found Bricklet port C (spidev: /dev/spidev0.0, driver: gpio, name: GPIO25, num: 25) <I> <bricklet.c:315> Found Bricklet port D (spidev: /dev/spidev0.0, driver: gpio, name: GPIO26, num: 26) <I> <bricklet.c:315> Found Bricklet port E (spidev: /dev/spidev0.0, driver: gpio, name: GPIO27, num: 27) <I> <bricklet.c:315> Found Bricklet port F (spidev: /dev/spidev0.0, driver: gpio, name: GPIO24, num: 24) <I> <bricklet.c:315> Found Bricklet port G (spidev: /dev/spidev0.0, driver: gpio, name: GPIO7, num: 7) <E> <bricklet_stack_linux_spidev.c:263> Could not find line GPIO7 <I> <main_linux.c:579> Brick Daemon 2.4.6 stopped These systems are all Raspberry Pi 3 Model A Plus Rev 1.0 with a HAT Brick. Downgrading to brickd 2.4.5 fixed the problem on all four systems, for now. Is this a known issue?

Your photo does not show the motor type, but it shows "moons". Go to the moons website, look up the motor, click "recommended options" for cables etc. example

Moritz, In my experience, the Outdoor Weather Bricklet + TH-6148 is the best choice when you want reliable reading of ambient temperature and humidity. I have 4 of these sensors running, indoors and outdoors, all communicating wirelessly with the same Outdoor Weather Bricklet and can recommend it without reservations. Any T/H sensor inside a computer case will always give a reading that is off, because the temperature inside the box will be higher than the ambient temperature. The difference (inside box vs ambient) will change depending on conditions such as ventilation, room temperature, load of your CPU, etc. so is difficult to compensate for. The TH-6148 is electrically isolated from your system, and you can more easily experiment with its location. Location matters a lot for T/H sensors. The TH-6148 can also be read by anybody, directly, because it has its own display, which always works, no software needed. Many people appreciate this. Good luck!

Unfortunately, AFAIK, the individual values can not be accessed in any way; the calculation of the IAQ is a black box: I can recommend the CO2 Bricklet (unfortunately, this has become quite expensive) and the Particulate Matter Bricklet.

Hi, The context (hardware, software, ...) of your question is not clear to me. Maybe you are using a Warp charger? There isa separate forum for that.

Fixed. Multiple resets and reboots did not fix this; unplugging the system from power fixed it. Interesting. Solved!

Hello, I am having a small problem with the GPS Bricklet 2.0 (FW 2.0.7). When I set the fix LED configuration to 4 (PPS) this effectively switches the LED off. With a GPS Bricklet 3.0 this works as expected: the LED blinks once per second. Both Bricklets have a fix. What am I doing wrong?

Thanks.

Hello, The LED Strip Bricklet 2.0 can be connected to the DC power supply line for the LEDs it controls. What is the maximum DC voltage the Bricklet can safely handle? I can't find this in the docs.

Or use a short ribbon cable to put the Pi and the HAT next to each other, instead of on top of each other.

Sigvald, Could it be that your hardware does not supply enough power? If that happens, the GPS Bricklet can seem to work normally, but it never finds satellites.
