librfid_main and anticollision

[Martin Garben]

Hi,

I used mifare_main and librfid_main for my standalone version of the reader.
But I have big trouble with two cards.

Layer2_open fails if I have two cards at the reader at the same time.
I use exactly the same coding for the standalone version as I did for 
the host version, but at layer2_open the reader hangs up.

(after reader_open) First I do a
rfid_layer2_init(struct rfid_reader_handle *rh, unsigned int id)
successfully and then a
rfid_layer2_open(struct rfid_layer2_handle *ph)

This works perfectly hosted and standalone for one card.

Did anyone get this running before for two mifare-classic cards?

I dont know whats wrong, because the hosted version is running fine and 
I dont have any problems - probably with the anticollision!?

This also leads to my second question: Is the watchdog sleeping? Even if 
the reader hangs up and only a replug gets it running again, I have 
activated the watchdog in main.c:
wdt_init();
(and ever loop in main a wdt_restart();)

Why is the watchdog not restarting the reader when layer2_open fails and 
the reader is "hanging"?

Best regards, Martin
