I got the CF STEM Ranging bundle over the holidays and have been trying to get it working. I successfully completed the getting-started-with-the-crazyflie-2-0 tutorial but I got stuck on the getting-started-with-stem-ranging-bundle tutorial; when I run the script the CF connects (i.e. the GREEN LED for both the CF and CrazyRadio are ON.) but it just sits there motionless.
I began investigating and came across a number of strange issues. I've been able to solve most of the issues via existing posts on these forums so I thank you all for that. There are still a few problems that I've not been able to solve though. One in particular is with the Multi-Ranger (MR) deck. When I power on the CF with (or without) the MR deck connected, the self-test passes as expected. However, after the self-test, with the MR deck connected, both BLUE LED's are ON but the RED LED flashes 5 or 6 times for about 1 second and then OFF for 1 second. Rinse and repeat. I can still connect to the Crazyflie Client. Here is the output from the main menu, Help -> About -> Debug:
