Calculate AOA with the PDoA kit

I’m using the Beta_PDoA_Tool_Kit and I’ve also read the article Angle of Arrival Estimation Using Decawave DW1000 Integrated Circuits including AOA calculation methods. I would like to know if it is this formula: (1 / 0.95) arcsin (PD / pi) can allow me to calculate AOA for this Kit (with PD = P (the “P” given by the Beta_kit)).
Thanks for any help,

Would be good to know for me also. Can anybody verify this Formula?
Thanks for any help

Sorry for such late reply.
The correct formula for this kit is arcsin (PD / 180 / 0.9).
P returned by the kit is in degrees, and antenna elements separation is 0.9*lambda/2.
