Hello First of all I truly appreciate the work. Thanks for the effort. Our solution. We are trying to send some data from the android HCE mimicking type 4 tag to the nfc reader SCL3711(using nfcpy). The whole solution works perfectly when the android phone is locked but when the phone is unlocked , time out error is thrown. I have tried changing the time out based on forum search to 16 which is 3 seconds for non_dep_to in pn53x.py but the results are very inconsistent. Sometimes it works and most of the times, it does not. Can you please help me ? Following are the logs for the locked and unlocked phone in the python library Locked phone(works) polling for NFC-A technology InListPassiveTarget command with timeout 1000 ms >>> 0000ff04fcd44a0100e100 <<< 0000ff00ff00 <<< 0000ff11efd54b01010004200408f6a0c90578807002e000 found NFC-A target @ 106 kbps found target TTA br=106 cfg=040020 uid=08f6a0c9 ats=0578807002 init TTA br=106 cfg=040020 uid=08f6a0c9 ats=0578807002 select file >>> 00a4040007d276000085010100 1.039s RFConfiguration command with timeout 100 ms >>> 0000ff06fad432020b0b0fd300 <<< 0000ff00ff00 <<< 0000ff02fed533f800 RFConfiguration command with timeout 100 ms >>> 0000ff04fcd4320403f300 <<< 0000ff00ff00 <<< 0000ff02fed533f800 InDataExchange command with timeout 2550 ms >>> 0000ff10f0d4400100a4040007d2760000850101006d00 <<< 0000ff00ff00 <<< 0000ff05fbd5410090005a00 <<< 9000 select file >>> 00a4000002e103 1.039s RFConfiguration command with timeout 100 ms >>> 0000ff06fad432020b0b0fd300 <<< 0000ff00ff00 <<< 0000ff02fed533f800 RFConfiguration command with timeout 100 ms >>> 0000ff04fcd4320403f300 <<< 0000ff00ff00 <<< 0000ff02fed533f800 InDataExchange command with timeout 2550 ms >>> 0000ff0af6d4400100a4000002e1036100 <<< 0000ff00ff00 <<< 0000ff05fbd5410090005a00 <<< 9000 read binary 0 to 15 >>> 00b000000f 1.039s RFConfiguration command with timeout 100 ms >>> 0000ff06fad432020b0b0fd300 <<< 0000ff00ff00 <<< 0000ff02fed533f800 RFConfiguration command with timeout 100 ms >>> 0000ff04fcd4320403f300 <<< 0000ff00ff00 <<< 0000ff02fed533f800 InDataExchange command with timeout 2550 ms >>> 0000ff08f8d4400100b000000f2c00 <<< 0000ff00ff00 <<< 0000ff14ecd54100000f20003b00340406e1040032000090009b00 <<< 000f20003b00340406e104003200009000 CC = 000f20003b00340406e10400320000 (15 bytes) Capabilities: Ver=2.0, MLe=59, MLc=52 select file >>> 00a4000c02e104 1.039s RFConfiguration command with timeout 100 ms >>> 0000ff06fad432020b0b0fd300 <<< 0000ff00ff00 <<< 0000ff02fed533f800 RFConfiguration command with timeout 100 ms >>> 0000ff04fcd4320403f300 <<< 0000ff00ff00 <<< 0000ff02fed533f800 InDataExchange command with timeout 2550 ms >>> 0000ff0af6d4400100a4000c02e1045400 <<< 0000ff00ff00 <<< 0000ff05fbd5410090005a00 <<< 9000 read binary 0 to 59 >>> 00b000003b 1.039s RFConfiguration command with timeout 100 ms >>> 0000ff06fad432020b0b0fd300 <<< 0000ff00ff00 <<< 0000ff02fed533f800 RFConfiguration command with timeout 100 ms >>> 0000ff04fcd4320403f300 <<< 0000ff00ff00 <<< 0000ff02fed533f800 InDataExchange command with timeout 2550 ms >>> 0000ff08f8d4400100b000003b0000 <<< 0000ff00ff00 <<< 0000ff17e9d541000010d901090254e1047965736877616e746890005100 <<< 0010d901090254e1047965736877616e74689000 connected to Type4Tag ATQ=0400 SAK=20 UID=08f6a0c9 ATS=0578807002 parse ndef message at offset 0 parsed nfc.ndef.Record('urn:nfc:wkt:T', '\xe1\x04', 'yeshwanth') ndef message complete at offset 16 RFConfiguration command with timeout 100 ms >>> 0000ff04fcd4320100f900 <<< 0000ff00ff00 <<< 0000ff02fed533f800 >>> 0000ff00ff00 Unlocked phone polling for NFC-A technology InListPassiveTarget command with timeout 1000 ms >>> 0000ff04fcd44a0100e100 <<< 0000ff00ff00 <<< 0000ff11efd54b010100046004082e390c05788070028c00 found NFC-A target @ 106 kbps found target TTA br=106 cfg=040060 uid=082e390c ats=0578807002 init TTA br=106 cfg=040060 uid=082e390c ats=0578807002 select file >>> 00a4040007d276000085010100 1.039s RFConfiguration command with timeout 100 ms >>> 0000ff06fad432020b0b0fd300 <<< 0000ff00ff00 <<< 0000ff02fed533f800 RFConfiguration command with timeout 100 ms >>> 0000ff04fcd4320403f300 <<< 0000ff00ff00 <<< 0000ff02fed533f800 InDataExchange command with timeout 2550 ms >>> 0000ff10f0d4400100a4040007d2760000850101006d00 <<< 0000ff00ff00 <<< 0000ff03fdd54101e900 [PN53x Error 0x01] Time out, the Target has not answered while reading ndef: TimeoutError(None) connected to Type4Tag ATQ=0400 SAK=60 UID=082e390c ATS=0578807002 RFConfiguration command with timeout 100 ms >>> 0000ff04fcd4320100f900 <<< 0000ff00ff00 <<< 0000ff02fed533f800 >>> 0000ff00ff00
