Good day everyone.
I'm pretty new to NFC energy harvesting but I like to think that I have a strong background on electronics. I have the OM2NTP5332 board that successfully powers my circuitry when I approach a mobile phone. So far, so good.
Here comes the problem.
My NFC device contains a NDEF message with a link so that on the mobile phone the user sees a popup and can click on it. Please notice that this link is updated often by the circuitry I developed.
I need to rewrite this NDEF message from time to time from the circuitry itself but it fails everytime since (I guess) the memory has been locked by the arbiter to the RF interface.
Since the main goal is to be 100% effortless from the user perspective, I cannot issue any custom command to the NTAG5 from the RF interface, simply plain reading.
I was thinking about using SRAM copy on boot option but unfortunately it supports only up to 64 bytes (and I need slightly more than 128).
Any suggestions how to solve this with the NTAG5?
Many thanks to anyone willing to help!
