hello,
I am working on NT3H2211 NTAG I2C.
I Could read/ write to the NFC chip through the host microcontroller and a NFC device.
Now all of sudden the I can neither read nor write into the NFC chip through I2C from the host MCU, but I can read/ write NDEF mesages through my mobile phone (NFC device). I can also read registers using the NXP Android app.
I check the I2C pin, everything is correct.
Can someone please tell me whats going on here?
Thank You
Rao
Yes, and I tried with a new ntag and I can read and write to it from the same bus
With new Ntag I can read and write through I2C, with the old Ntag I cannot read and write through I2C
Hello Jeff,
I scanned through all the I2C address, I get NAKs
