Hi,
I have been playing around with the configs but I could not get Mode-3 to activate. What should I change for cs configs and the prj.conf file in order to activate it?
struct bt_le_cs_create_config_params config_params = {
.id = CS_CONFIG_ID,
.main_mode_type = BT_CONN_LE_CS_MAIN_MODE_2,

.max_main_mode_steps = 5,
.main_mode_repetition = 0,
.mode_0_steps = NUM_MODE_0_STEPS,
.role = BT_CONN_LE_CS_ROLE_INITIATOR,
.rtt_type = BT_CONN_LE_CS_RTT_TYPE_AA_ONLY,
.cs_sync_phy = BT_CONN_LE_CS_SYNC_1M_PHY,
.channel_map_repetition = 3,
.channel_selection_type = BT_CONN_LE_CS_CHSEL_TYPE_3B,
.ch3c_shape = BT_CONN_LE_CS_CH3C_SHAPE_HAT,
.ch3c_jump = 2,
};
bt_le_cs_set_valid_chmap_bits(config_params.channel_map);
err = bt_le_cs_create_config(connection, &config_params,
BT_LE_CS_CREATE_CONFIG_CONTEXT_LOCAL_AND_REMOTE);
if (err) {
LOG_ERR("Failed to create CS config (err %d)", err);
return 0;
}
k_sem_take(&sem_config_created, K_FOREVER);
err = bt_le_cs_security_enable(connection);
if (err) {
LOG_ERR("Failed to start CS Security (err %d)", err);
return 0;
}
k_sem_take(&sem_cs_security_enabled, K_FOREVER);
