Re: LPS node failed to set dtr/rts

One more thing. When Linux tries to check if the device is a modem it will send commands to it. Unfortunately some of these contain 1 and 0, which will reset the anchor address (I think the final state is 0). To make things easier you could disable this so you keep the correct anchor address and can...

Re: basicparam.py not changing value?

Hi,

This issue seems to be fixed in the latest commit on github (link). But I'm not really sure why reading the parameters an extra time was causing it. Needs more investigation.

Re: Why do I get Type Error exception when I run default ramp.py?

Hi,

Are you getting this stacktrace at the "end" of the demo? Could you copy paste the full stacktrace?

Re: Buzzerdeck not working

The buzzer uses the two marked pins in the photo. Could you check so that these have proper contact with the expansion connector?

Re: Buzzerdeck not working

I just tried the 2016.09 firmware release and it's working like it should with the Buzzer deck. From the log you pasted the board is being detected which means you should hear a start-up sound and a calibration sound when you start the Crazyflie. So it looks like there might be something with the ha...

Re: ZMQ & Thread

Hi, The python client API is asynchronous for most things, using callbacks when the communication is done and data is available. The callbacks are made in the context of the threads in the API and should return quickly (i.e no blocking or heavy processing). To see how it should be used have a look a...

Re: Buzzerdeck not working

Hi!

Could you check if the board is detected? In the console you should see a printout that looks like this:

Code: Select all

DECK_INFO: Found 2 deck memories.
DECK_CORE: 2 deck enumerated
Could you paste the complete console output?

Re: Exception When Compiling ramp.py Example

Hi,

I've tested this with the latest version of the crazyflie-lib-python (86a1e6b9770b24b3e934cafc6731540ae44c8dea) and it's working for me. Did you try cloning the crazyflie-lib-python and installing it in "Editable mode" (see the README for more information)?

Re: Big quad deck & UART

Hi Maxime,

Sounds like an interesting project! No, but on the Big quad deck there's a GPS connector that is connected to a UART on the Crazyflie 2.0. Would it be possible to use that instead? The connector is not mounted on the board, but it's a standard connector and it's easy to solder it.
