I'm working on PN5180 module to read data from my ePassport (ICAO 9303). I can send RATS - ATS, PPS, so technically, now i can exchange data using APDU command. And I can select AID, read EF.CardAccess file but I can't GET CHALLENGE, my eMRTD always response trailer "0x6D 0x00", which means "Instruction code not supported or invalid"
Here my code trace:
RATS: 0xE0 0x80
ATS: 0E 78 77 D4 03 4D 4B 6A 43 4F 53 2D 33 37

ET CHALLENGE: 0E 00 00 00 84 00 00 08

I really do not understand this problem, Although i have used PN532 to communicate, i could read my ePassport with the same APDU GET CHALLENGE (using InlistPassiveTarget and InDataExchange).
If anyone see this post and worked with PN5180 or smart card before, pls let me know. I expect it responses 8 bytes random and trailer 0x90 0x00
