Home assistant NFC reader

Hi forum
i really really need some help!!

im trying to do this project GitHub - klaasnicolaas/ha_nfc_scanner: Scan NFC tags/cards with MQTT action to Home Assistant

but has run into some trouble and it seems the owner is not responding to created issues!

so i have succesfully uploaded the code :
ha_nfc_scanner.ino (Also attached)
config.h (Also attached)
and can scan tags (change mode by setting readUIDMode to true, in the ha_nfc_scanner.ino file)
so far so good..

So i have 2 tags i want to play with or test with
and have coded these uid into the config file:

#define NUM_ACCEPTED_UIDS 2 //<-----------------CHANGE THIS IF ADDING CARDS!!
NFCTag NFCTags[NUM_ACCEPTED_UIDS] = {
  // It is neccessary to account for UID length since a 7 byte ID could contain a 4 byte ID, which would cause a misfire
 //  #0    #1    #2    #3    #4    #5    #6   #Tagname
  {{0xA, 0xE0, 0x39, 0x16}, "ChipO", false, 0, false, {0}},
  {{0xAB, 0x55, 0xE, 0x1C}, "CardO", false, 0, false, {0}}
};

here comes the trouble...
Only ONE (always the first tag) will be sent to my MQTT no matter what i do..

My setup / hw is :
NodeMcu Lua WIFI Internet Things Development Board ESP8266 CP2102 for Arduino

You'll probably do better if you post your code in the forum. Many members are reluctant to follow links off the Arduino site.
