Re: Problem that using big quad with loco positioning

Good, you figured it out, was maybe not clear enough, easy to get used to stuff :oops: Do you have the CF2 in the middle of the positioning space? You can try walking around with the CF2 and write the positions many times. The default output power for the loco deck might be a bit low. Yeah. I locat...

Re: Problem that using big quad with loco positioning

It could be related to this bug but since you are running TDoA it is less likely. Have you tied not enabling the OSD? CFLAGS += -DBQ_DECK_ENABLE_OSD Could be UART driver that is not playing well with the loco deck. Thank you for your help I edited config.mk like this. ## Redirect the console output...

Re: Problem that using big quad with loco positioning

Well... What does that mean? write down it in config.mk? like this. Ex First) CFLAGS += -DBQ_DECK_ENABLE_OSD or comment out it in config.mk? like this. Ex Second) #CFLAGS += -DBQ_DECK_ENABLE_OSD --------------------------------- and I solved "core_cm4.h" error by installing new VM image.

Re: communication between two CF2.0

Thank you!!

I want to log GPS data which is consisted of various data types and transmit the data to the other CF 2.0.

Can I ask one more?
Will it be possible to transmit more than 50 variables (GPS data) through peer-to-peer communication?

communication between two CF2.0

Hello! I am kind of stuck doing my undergraduate project, because I am not sure how to make crazyflies to communicate each other. 1. Is there any way to send log data from a CF 2.0(A) to a CF2.0 (B)? If possible, please let me know... 2. If there is no way to send log data from CF 2.0 to CF 2.0, I t...

Oh, I see. Thank you. :D

Delay update log(?)

Hi. Currently, I am working on registering values on log and receiving data using python3 library. I tried to update integer data(65 to 90) in order and monitored the received data with Crazyflie PC client. But the received data wasn't matching with the data I updated. Here is my code and result. #d...

Re: Crazyflie 2.0 communicate with Gps module by UART.

Yes you need the debug adapter kit or make your own cable + a debugger like the STLinkV2. You might be able to find the problem without the dubugger so try that first. Back to the question is the hard fault related to your code (my best guess is a memory overflow problem). Aha.. Okay. Thank you. I'...

Re: Crazyflie 2.0 communicate with Gps module by UART.

Well done so far! The 2xRed + blue most likely is a hard fault or an ASSERT . Easiest to find out why is to use a debugger. Does the problem happen if you don't get any characters from the GPS, e.g. turn it off? Tobias, Thank you for reply. :) I am the first to use debugger in embedded system. Can ...
