PN532-SPI on ESP8266 & wifimanager

by nicozozo on Sun Mar 15, 2020 3:51 am

Hi,
I use a Wemos D1 mini with NFC532 wired in SPI, it work well.
I also use the wifimanager to be able to access the wemos, and get info from readed RFID badges.

When my Wemos boot, the wifimanager library give an ip to the wemos which I can ping, until I call the line :
success = nfc.readPassiveTargetID(PN532_MIFARE_ISO14443A, uid, &uidLength);

the the ping diseapear, and re-appear randomly (3 reply and then 10 or 20 timeout),

If I comment the line, the wemos run for hours with a reply.

I try different value for
nfc.setPassiveActivationRetries(0x20);
nfc.SAMConfig();

no luck.
any help will be appreciate.
