Hi, did you solve this problem? I have also tried, from the two antenna ranging results the time synchronization is correct, but the phase difference is still not correct, I do not know if there is a problem with my calculation method, I am using the IP_POA in the two chips, thanks

which pins did you use when syncing?

Have you solved the problem? How to calculate the right PDOA from the IP_POA in the two chips?
