Multiple tag/anchor pairs calculation distances at the same time

Hi,

I have multiple dwm1001 dev boards and I flashed the github examples on some modules (https://github.com/Decawave/dwm1001-examples)

Lets say I have 4 modules, 2 tags: T1 and T2, 2 anchors: A1 and A2. I can send distances requests to A1 via UART so its calculates its distance to T1 or T2. Also, I can send distances requests to A2 to calculate its distance to T1 or T2. This works great.

However, if I ask A1 to calculate its distance to T1 and at the same time A2 to calculate its distance to T2, no one can gather the distance as if the messages are lost.

Why can’t two distinct pairs of tag/anchor work at the same time?

Thanks
