NTAG I2C plus data-rate?

kennethical — Tue, 10 Jul 2018 15:57:35 GMT

Hello,

Marketing documents indicate that pass-through mode can acheive a data-rate of "~8 KBps ". While I'm sure that's somewhat optimistic, I am having trouble achieving even one quarter of that between my device and my application.

My application is hosted on an Android phone.

Any hints on how to achieve the best performance in pass-through mode would be appreciated, thank you.

What is your device and your application? Is it OM5569-NT322E and NTAG I²C Demo Android App ?

Both my own, but implementations have been basically templated on the demonstration materials.

With a few changes to my device's code to make it interoperate with the official demo app's speed test, I see even worse performance than with my app.

Thanks.

How about making your device running the firmware for OM5569-NT322E, https://www.nxp.com/downloads/en/snippets-boot-code-headers-monitors/SW3647.zip ? Would it make a difference?

Have a great day,
