PN7220 REJECT DISCOVERY

uhuntu — Wed, 31 Jul 2024 05:29:08 GMT

Hi there, I met a trouble, when I was porting to Android 13 with MT8390, the NfcService was continually restart due to watch dog time out. Please check the attached for details information.

I was analyzing by myself as below:

In packages/apps/Nfc/nci/jni/NativeNfcManager.cpp - void startRfDiscovery(bool isStart) { - sNfaEnableDisablePollingEvent.wait(); // wait for NFA_RF_DISCOVERY_xxxx_EVT

Due to the host initialize discovery procedure, but never receive the acknowledge then case NfcService' WatchDog timeout.

In system/nfc/src/nfa/dm/nfa_dm_discover.cc - static void nfa_dm_disc_sm_idle(tNFA_DM_RF_DISC_SM_EVENT event, tNFA_DM_RF_DISC_DATA* p_data) { - case NFA_DM_RF_DISCOVER_RSP:

p_data->nfc_discover.status equals to NFC_STATUS_REJECTED, as is Discovery was be Rejected, please help to analyze the root cause of this, or I need to anything config in my conf.zip attachment?

After that, I see deactivate procedure is up, but why it will cause NfcService restart ?
