pc-ble-driver CODED PHY not working

Hi,

Is the MAX CONNECITON INTERVAL the only modification you have made? What function is returning NRF_ERROR_RESOURCES?

Hi,

sd_ble_gap_connect() returning NRF_ERROR_RESOURCES means either:

- Not enough BLE role slots available. Stop one or more currently active roles (Central, Peripheral or Observer) and try again.

or

- The event_length parameter associated with conn_cfg_tag is too small to be able to establish a connection on the selected ble_gap_scan_params_t::scan_phys. Use sd_ble_cfg_set to increase the event length.

It is probably the latter, can you check?

Hi, I added this, but getting NRF_ERROR_INVALID_PARAM error:

memset(&ble_cfg, 0x00, sizeof(ble_cfg));
ble_cfg.conn_cfg.params.gap_conn_cfg.event_length = BLE_GAP_EVENT_LENGTH_CODED_PHY_MIN;
ble_cfg.conn_cfg.params.gap_conn_cfg.conn_count = BLE_GAP_CONN_COUNT_DEFAULT;

error_code = sd_ble_cfg_set(m_adapter, BLE_CONN_CFG_GAP, &ble_cfg, ram_start);

Hi, 

The NRF_ERROR_INVALID_PARAM error means that you have supplied an invalid cfg_id. Have a look at sd_ble_cfg_set.

Can you please provide a code example how to do this? The documentation is very unclear. Thanks!

Update: calling the below is not failing anymore on sd_ble_cfg_set(), but now sd_ble_gap_connect() is failing on NRF_ERROR_INVALID_STATE. Peripheral is Nordic Long-Range in CODED PHY mode. nRF Connect on phone is connecting with no issue. Please help to resolve. Thanks!

memset(&ble_cfg, 0x00, sizeof(ble_cfg));
ble_cfg.conn_cfg.conn_cfg_tag = conn_cfg_tag;
ble_cfg.conn_cfg.params.gap_conn_cfg.event_length = BLE_GAP_EVENT_LENGTH_CODED_PHY_MIN *3;
ble_cfg.conn_cfg.params.gap_conn_cfg.conn_count = BLE_GAP_CONN_COUNT_DEFAULT;

error_code = sd_ble_cfg_set(m_adapter, BLE_CONN_CFG_GAP, &ble_cfg, ram_start);

Are you in a connection already when you call sd_ble_gap_connect()?
