HI,I’m new here.
I layout the PCB according to the loco node Sche.I solder the ICs by hand.And flashing the firmware successfully,but it seems that lps25h not work good because the window print the msg"pressure sensor test fail".maybe the lps25h is too small to solder well.I wonder does this sensor neccesary in tdoa2 to fly a swarm of CFs?
thanks a lot.

No, the lps25h is not used in TDoA ranging mode, the pressure is transmited in the TWR messages but has not been used in the Crazyflie so far.
