the duration field in ble_gap_adv_params_t should be set in in 10 ms units, but currently the timeouts are implemented wrong. APP_CFG_NON_CONN_ADV_TIMEOUT is set in seconds but APP_CFG_CONNECTABLE_ADV_TIMEOUT is set in milliseconds which is not consistent. I suggest the following changes in components/ble/ble_services/eddystone/es_adv.c and examples/ble_peripheral/ble_app_eddystone/es_app_config.h:
static void get_adv_params(ble_gap_adv_params_t * p_adv_params,
bool non_connectable,
bool remain_connectable)
{
// Initialize advertising parameters (used when starting advertising).
memset(p_adv_params, 0, sizeof(ble_gap_adv_params_t));
// Non-connectable
p_adv_params->properties.type = non_connectable
? BLE_GAP_ADV_TYPE_NONCONNECTABLE_NONSCANNABLE_UNDIRECTED
: BLE_GAP_ADV_TYPE_CONNECTABLE_SCANNABLE_UNDIRECTED;
p_adv_params->p_peer_addr = NULL; // Undirected advertisement.
p_adv_params->filter_policy = BLE_GAP_ADV_FP_ANY;
p_adv_params->interval = non_connectable ? m_adv_interval : APP_CFG_CONNECTABLE_ADV_INTERVAL_MS;
p_adv_params->duration = non_connectable
- ? APP_CFG_NON_CONN_ADV_TIMEOUT
- : (remain_connectable ? 0 : APP_CFG_CONNECTABLE_ADV_TIMEOUT);
+ ? APP_CFG_NON_CONN_ADV_TIMEOUT * 100
+ : (remain_connectable ? 0 : APP_CFG_CONNECTABLE_ADV_TIMEOUT * 100);
p_adv_params->primary_phy = BLE_GAP_PHY_1MBPS;
}
#define APP_CFG_NON_CONN_ADV_TIMEOUT 0 //!< Time for which the device must be advertising in non-connectable mode (in seconds). 0 disables the time-out. #define APP_CFG_NON_CONN_ADV_INTERVAL_MS 1000 //!< The advertising interval for non-connectable advertisement (in milliseconds).
