Re: How to log bare DWM1000 positioning data?

Just for updating! I succeeded it by removing the part when !quadIsFlying in kalmanCorePredict(). Thank you so much Kristoffer for your nice explanation.

Re: How to log bare DWM1000 positioning data?

Thank you for your suggestions. However, I still haven't totally understood that which parts I should modify. As I have a look on "kalman_core.c", also "mm_tdoa.c", there're just a bunch of functions to estimate the position from each sensor. However, I haven't seen any parts of the code or any othe...

I mean "modify the code on "kalman_core.c" https://github.com/bitcraze/crazyflie-firmware/blob/5ca8853/src/modules/src/kalman_core.c#L398-L459 and flash new firmware to Cra...

Re: Crazy Bolt with Loco Tag always lost packet(connection) after connecting for a few seconds

Oh! I haven't attached the antenna on the Bolt. Thank you for your reply, however, I can try it on this Friday and we'll see how it's go.
