did you compile the firmware using DDECK_FORCE flag to force it to compile your virtual deck? see the tutorials if not.
also, I recommend posting the output from the console (self test results)

unrelated to lighthouse issues, I also found that in some crazyflies the motor PWM values differ consistently while hovering. In many cases two motors will have higher values and the other two will have lower values. you can use motors.m1 .. motors.m4 log variables to test this while hovering. Repla...

if you have access to a print shop, it might be simpler/cheaper to print something like this . works well in the correct scale. use high contrast.

update 2: it works! the only thing is that the rate is ~1.5KB/sec (both radio and USB). in the CPP implementation by whoenig it was ~3 times faster.
anyway I am considering making some improvements for performance, any suggestions welcome.
the modified code is posted as a PR in the cflib github

just a quick update, after some tests with crazyflie_tools, downloading using radio or USB does not matter much in terms of speed, on USB I get 4-9KBps and on radio around 7KBps. I started writing the python functions to allow downloading and will update again.

Thanks for wyour reply whoenig! I wrote the post and found out about your answer only later.. :oops: I have a few specific questions after studying your answer- first - I understand the usddeckRead method used in the firmware is relevant only for an active logging session which was stopped but the d...

retrying if anyone has insights.. I dug a bit deeper to find - enum MemoryType { MemoryTypeEEPROM = 0x00, MemoryTypeOneWire = 0x01, MemoryTypeLED12 = 0x10, MemoryTypeLOCO = 0x11, MemoryTypeTRAJ = 0x12, MemoryTypeLOCO2 = 0x13, MemoryTypeLH = 0x14, MemoryTypeTester = 0x15, MemoryTypeUSD = 0x16, // Cra...

Hello. I noticed that in crazyflie_cpp (equivalent of cflib, the base for crazyflie_ros) there is a function that downloads the latest log file from the SD card over radio / usb. I was looking for the equivalent method in cfLib , if there is any. if not, where should I start (interfaces) when trying...

will be happy to hear if there is any update. thx!

update: after resetting, if using flow sensor, I get the message - "Error while initializing the PMW3901 sensor"

So currently I'm abandoning this method.
