We're using two nrf54:s, one DK (initiator) and one custom PCB with 2x antennas (reflector)
I've tried adjusting the samples so that multiple antenna paths are supported:
```
#Reflector
CONFIG_BT_RAS_MODE_3_SUPPORTED=n
CONFIG_BT_RAS_MAX_ANTENNA_PATHS=2
CONFIG_BT_CTLR_SDC_CS_MAX_ANTENNA_PATHS=2
CONFIG_BT_CTLR_SDC_CS_NUM_ANTENNAS=2
CONFIG_BT_CTLR_SDC_CS_STEP_MODE3=n
CONFIG_BT_CTLR_SDC_CS_ROLE_REFLECTOR_ONLY=y
# Initiator
CONFIG_BT_RAS_MODE_3_SUPPORTED=n
CONFIG_BT_RAS_MAX_ANTENNA_PATHS=2
CONFIG_BT_CTLR_SDC_CS_MAX_ANTENNA_PATHS=2
CONFIG_BT_CTLR_SDC_CS_NUM_ANTENNAS=1
CONFIG_BT_CTLR_SDC_CS_STEP_MODE3=n
CONFIG_BT_CTLR_SDC_CS_ROLE_INITIATOR_ONLY=y
```
...and then in each config struct, change
```
- .tone_antenna_config_selection = BT_LE_CS_TONE_ANTENNA_CONFIGURATION_A1_B1,
+ .tone_antenna_config_selection = BT_LE_CS_TONE_ANTENNA_CONFIGURATION_A2_B1,
```
but I've also tried A1_B2 - with A1_B2 I get hci status 0x12 (-EINVAL basically) so I guess A2_B1 is correct, but that gives hci status 0x0d:
```
uart:~$ [00:21:38.045,606] <wrn> bt_hci_core: opcode 0x2093 status 0x0d
```
and `bt_le_cs_set_procedure_parameters` returns -ENOMEM. There's a comment about needing more RAM if multipath is used, but no clarification which buffer or which Kconfig governs it. So is it possible to get a minimal working sample instruction on how to get the CS samples to work with a 2x1 antenna path setup?
