URL: https://github.com/apache/mynewt-nimble/issues/2129
I use aic8800 bluetooth adapter with Nimble (Linux port). I got problem on
this hardware with BLE_EXT_ADV option: when a client connects to my server
under Nimble the server doesn't get BLE_GAP_EVENT_CONNECT event. Next I found
that server gets ATT message but drops it because connection is not
estableshed. I found that ble_gap_rx_conn_complete may not call in
ble_hs_hci_evt.c file in ble_hs_hci_evt_le_conn_complete and
ble_hs_hci_evt_le_enh_conn_complete functions:
`#if MYNEWT_VAL(BLE_EXT_ADV)
if (evt.status == BLE_ERR_DIR_ADV_TMO ||
evt.role == BLE_HCI_LE_CONN_COMPLETE_ROLE_SLAVE)
{
/* store this until we get set terminated event with adv handle */
memcpy(&pend_conn_complete, &evt, sizeof(evt));
return 0;
}
#endif
return ble_gap_rx_conn_complete(&evt, 0);
`
As I understand Nimble wait for stopping of advertising but on this adapter
this event doesn't receive or receives after ATT message.
Next I tried to fix file this manner:
` if (evt.status == BLE_ERR_DIR_ADV_TMO ||
evt.role == BLE_HCI_LE_CONN_COMPLETE_ROLE_SLAVE)
{
memcpy(&pend_conn_complete, &evt, sizeof(evt));
if (evt.role == BLE_HCI_LE_CONN_COMPLETE_ROLE_SLAVE) {
printf("ble_hs_hci_evt_le_enh_conn_complete: SLAVE role,
registering connection immediately\n");
/* Fall through to register connection immediately */
} else {
/* DIR_ADV_TMO case - wait for ADV_SET_TERMINATED */
return 0;
}
`
and this solved my problem.
I don't know much about Nimble code, but maybe this is a bug?
