Re: Cf2 sets anchor address in TDOA3 mode

Can the current anchor position be written to the anchor point while burning the anchor point program?I want to skip the python client :lol:

Re: Cf2 sets anchor address in TDOA3 mode

So TDOA3 can't write static XYZ in your code, it can only write through a python client. Right?

Cf2 sets anchor address in TDOA3 mode

I find that the code in crazyflie firmware, the TDOA3 schema code that does not write anchor XYZ, can only be written with python clients??? :?:

crystal oscillator

I found that the RC oscillator used by the master control of LPS did not use external crystal oscillator. Would the effect be better if the external crystal oscillator was added?The external crystal oscillator I/O seems to be occupied by the barometer and LED lights!

Re: AntenaDelay

I'm going to use PA for the anchor point plus PA for the plane.Or make an airplane with PA as anchor point + PA, the data of TDOA is not correct

Re: AntenaDelay

The antenna is the same, namely the antenna and DWM1000 chip added a PA, as shown in the figure.In that case, the antenna delay need not be changed, where to change with TDOA mode?Timestamp?

Re: AntenaDelay

To be exact, DWM1000 with power amplifier is tested with Anchor mode and tag mode in LPS. One Anchor and one tag, the test results are more consistent with the real results. Although there is a little deviation, it is adjustable, but the data analyzed by the aircraft end is wrong with 8 TDOA2 or TDO...

Re: AntenaDelay

TWR mode ranging is correct, but TDOA mode ranging is wrong, because I used DWM1000 power amplifier, how should the antenna delay and time be modified?

Re: AntenaDelay

Use DWM1000 with PA, the distance is not accurate, need to revise where
