When pin IO_2 was removed, the other modules operated normally. I'm currently working on three drones, all three of which were removed from pin IO_2, and the problem was solved. We suspected damage to the sensor, but the same problem occurred when we connected the new sensor and solved it the same w...

In fact, we are already soldering and using it. Lps soldering directly, and flow deck connected by wire and soldering. I soldering uwb first to check the connection and performance, and connected the flow deck. As a result, you can see that the well-connected uwb is not connected well and the flow d...

When both decks are connected and powered on, a failure appears in the console output of the spi connection sensor. Of the two spi, the normal uwb connection is not good, and sometimes it is uwb but not flow_deck. If the exact cause of this is a simple timing problem, random time extension seems nec...

I tried to proceed with the experiment that you said. Unfortunately, I tested it again today and it didn't work. More precisely, it happens very often. We are thinking about other ways because connection problems occur so often that we cannot trust to experiment with drones. Based on the connection ...

It was a very helpful article. I am currently using Crazyfly-Bolt, radio dongle, flow v2, uwb sensor. I am modifying the code based on the above article. So far, we've been getting very stable results to modify the latency. If there are no additional problems, I think it will be available without mu...

Of course. I used the firmware updated in September.
I wonder which part of the problem you tried to solve by updating.
I think it will be possible to adjust the same part to fit my environment.
Can you tell me the cause of the problem and the update part?
