Re: Importance of a fully charged battery

Thanks for the precision, so that means that the client is still working on Windows which is good (it has happend that the Windows build breaks when libs version are updated). I be leave we solved the node updated in an other thread.

Re: LOC Node Setup

A precision: there is no automatic calibration (yet) for the anchors, so you must configure the position of the anchors in order for the LPS to work as a positioning system. If you follow the getting started guide, setting the anchor position is part of it together with an explanation of the color c...

Re: Crazyflie Deck design

GS1 and GS2 should be cut (there is already a line connecting them, it is quite easy to cut the line between the pads with a cutter).

GS3 and GS4 should indeed be bridged.

Re: Loco positioning together with multi-ranger?

LPS and multiranger will work together with no problem electrically speaking. The only limitation might be that if putting all the decks on the top, one must be careful to not short the multiranger sensors (it seems to be clear of any metal but one should be careful). The multirange seems to cover a...

Re: External communication not only CF Radio Dongle

I do not think hooking on Syslink is a good idea: syslink is already a serial protocol that implements framing, that is a plus, but it is used for more than CRTP in the Crazyflie, power management and one wire memory access. The CRTP communication stack is already modular in the Crazyflie, there is ...

Re: Switching altitude measurement from downward ranger to upward

In principle I think that this should work fine. Practically though you might need two parameters: one to disable pushing the zranger to the EKF: https://github.com/bitcraze/crazyflie-firmware/blob/master/src/deck/drivers/src/zranger2.c#L139-L147 and one to enable pushing the up-measurement into the...

Re: Preload a trajectory in CF2 in firmware

Are you running the branch from iros or did you copy-paste only app.c in a more recent firmware?

Could you details a bit more what error you are getting and what is your environment (ie. OS, version of the compiler).

Re: Anchor ID's resetting after power-up

Glad that it worked! I also find the serial console more practical and it also gives access to more options like the TX power settings. The problem was most likely caused by Modemmanager: its a program that tries to detect a modem on newly connected serial ports. If you do not need to use any modem ...

Re: LOC Nide drivers

It is odd that it did not work on the first computer since the node now appears correctly as a serial port. Happy you got it to work on another computer though.

Re: Trying out the Crazyswarm

I think part of the problem might be that you are setting a different channel for each Crazyflie: one of the functionality that makes Crazyswarm very efficient and capable to control ~15 Crazyflie per radio is the use of broadcast packet to send the position of multiple Crazyflie at the same time. T...
