How to use nrf54L15-dk with external host through hci uart application

[Abhinav152]

Hi, 

I am trying to build an application using the nrf54L15-dk board and want to use the board as a controller. I run the application on the external host but got an error as controller responsive. Can you provide the details steps so that board can be use with external host.

can you also provide `Channel_Map` value please?

Hi , Foloowing are my channel map values 


cmd->conn_handle = 1e
cmd->config_id = 0
cmd->create_context = 1
cmd->main_mode_type = 1
cmd->sub_mode_type = ff
cmd->min_main_mode_steps = 2
cmd->max_main_mode_steps = 5
cmd->main_mode_repetition = 0
cmd->mode_0_steps = 3
cmd->role = 0
cmd->rtt_type = 0
cmd->cs_sync_phy = 1
cmd->channel_map_repetition = 0
cmd->channel_selection_type = 0
cmd->ch3c_shape = 0
cmd->ch3c_jump = 2
cmd->channel_map[0] = a
cmd->channel_map[1] = fa
cmd->channel_map[2] = cf
cmd->channel_map[3] = ac
cmd->channel_map[4] = fa
cmd->channel_map[5] = c0
cmd->channel_map[6] = 0
cmd->channel_map[7] = 0
cmd->channel_map[8] = 0
cmd->channel_map[9] = 0

Also, i tried with the values provided by NRF example using the below way but it didn't work. In this case all channel map values are 0

BT_LE_CS_CHANNEL_BIT_SET_VAL(cmd.channel_map, 0, 0);

BT_LE_CS_CHANNEL_BIT_SET_VAL(cmd.channel_map, 1, 0);

BT_LE_CS_CHANNEL_BIT_SET_VAL(cmd.channel_map, 23, 0);

BT_LE_CS_CHANNEL_BIT_SET_VAL(cmd.channel_map, 24, 0);

BT_LE_CS_CHANNEL_BIT_SET_VAL(cmd.channel_map, 25, 0);

BT_LE_CS_CHANNEL_BIT_SET_VAL(cmd.channel_map, 77, 0);

BT_LE_CS_CHANNEL_BIT_SET_VAL(cmd.channel_map, 78, 0);

BT_LE_CS_CHANNEL_BIT_SET_VAL(cmd.channel_map, 79, 0);

I am not sure exactly but I see at least two values not allowed by Spec:

- channel_map_repetition is allowed to be in the range from 1 to 0xff

- channels 1 and 23 are not allowed to be used during Channel sounding procedure.

Can you try to disable channel 1 and 23 by setting

cmd->channel_map[0] = 0x08
cmd->channel_map[2] = 0x4f

and see if it helps please?

Thanks for rectifying the issues. I want to test the LE securotuy mode for the CS feature 


Can you tell me how the NRF controller supports this Cs procedure and whether the controller sends any  event to the host so that security levels can be checked? Also i want to set this security level. I tried searching in the NRF code, but can you help to locate how sample examples has set the security level
