Data Comparison of NFC PN532 on Wemos Dl and MKR1000 Board through MQTT Protocol

This research focused on the comparison of data transfer process in NFC PN532 using two different transmission boards. Wemos Dl and MKR1000 used as the transmission board. The network built with MQTT protocol by using mosquitto message broker. NFC PN532, a transceiver module who works at l3,56MHz and supports several host interfaces used in this paper. SPI used as the interface between transmission board and NFC PN532. The testing mechanism is comparing the data received in server form NFC PN532 that transmitted through both MKR1000 and Wemos D1. The result showed that the use of one topic or two topics in MQTT protocol does not show big difference, but the data transmission using MKR100 is quite better and more balance than Wemos D1.
