Drone not flying with multi ranger deck

Post by ForgottenSea »

Hello, all. I recently bought a Crazyflie 2.1 with the multi ranger deck and when I attach it, the drone doesn't fly. It flies without it and I'm on the latest firmware.

Hi!

We need a bit more information about your problem:
  • Are you using any other expansion-decks ?
  • What do you see on the crazyflie itself (different LEDS ?)
  • Are you on master or the latest release 2020.06 with firmware
  • What do you see in the console tab in the cfclient?

Hello, I'm having the same issue here. Should I be creating a new thread or can i revive this one?

I have a crazyflie 2.1 I just got in the mail. I've attached a flow deck v2 to the bottom, and I can successfully connect. I've also updated the firmware/flowdeck via the windows cfclient.

When I attach the multi ranger deck, I am getting 5 red led flashes. On the documentation, 5 red flashes means "the drone was moved when powering on, try again" but obviously this is not the case.

What's the best way to troubleshoot this?
Thanks!

@traffens Generally it is better to create a new one, but let's continue here.

The reason you get five flashes is because the initialization failed. In your log you can see that the front sensor on the Multi ranger did not initialize.

Code: Select all

MR: Init front sensor [FAIL]
Send us an email at support@bitcraze.io and we will take it from there.

I have a question though and that is in which documentation you did read that 5 red flashes means "the drone was moved when powering on, try again". Is it not completely correct and I would like to update it. Thanks!
