We are working right now to measure latency and trying to improve the value on the PN7462. We are using ‘NfcrdlibEx1_BasicDiscoveryLoop’ example to do so. We are able to read the UUID of multiple ICODE SLIX tags by applying changes suggested by NXP. We tried ‘NfcrdlibEx1_BasicDiscoveryLoop’ example. Unfortunately the UUID reading delay seems to be very high. We have a requirement to finish reading of at least four tag’s UUID and Data within 300msec. The delay seems to be nearly 1 second with the above example code. Are there any variables or strategies to apply in order to achieve the goal of reading four tags within 300 mS? Using an o-scope we measure the following:
Inventory delay of 4 ICODE SLIX tags : 360ms
Inventory delay of 4 TI’s ITAG : 340ms
Inventory delay of 4 TI’s ITAG tag with same last UUID byte : 554ms
Thank you very much for your time.
