I wanted to set multiple initiators for Channel sounding,I don't know where to set it.

When I used the CS instance for distance measurement, I wanted to set multiple initiators. Therefore, I configured BT_CTLR_SDC_CS_COUNT to 3. However, I didn't know where to set it to 3. I changed it to 3 in this file, but after compiling, it reverted to 1. May I ask how to solve this?

Hi

You also need to set the CONFIG_BT_MAX_CONN=3 so that the application supports up to 3 connections in the first place. I would assume it says in the build log why the CS_COUNT is set back to 1.

Best regards,

After setting CONFIG_BT_MAX_CONN to 3, the reflector can connect to 3 initiators devices simultaneously, but these 3 devices do not perform ranging at the same time? Is there anything else that needs to be set up?
