I am a newer with NFC, now I use the RF430FRL152 reads temperature as a tag.
The schematic is shown as below
I used TRF7970ABP + MSP430G2553 board and RF430FRL15XH GUI Interface to test the tag:
1.Connect the board
2.Start the demo to getting the temperature and it worked
3.I clicked the Read All (an alert dialog appeared and I clicked ok)
4.I start the demo again, and the err occured. And the other button clicked with the same problem. Now I can do nothing with the Tag.
What happened to the Tag and how can I resolve this problem.
in addition, is there a Android demo for reading the temperature
Thanks

Hello Yahui,
that sounds very unusual that you do not have access to the device after pressing the "Read All" button. I tried that several times with my setup but still have access to the device.
If you have an NFC enabled smartphone you can try if the smartphone can detect the device. Even if I can not imagine how this would happen, but in worst case your memory is corrupted and you would need JTAG access to the device for reprogramming. The RF430FRL152HEVM offers a JTAG connection for the MSP430 programming tool.
An Android demo app is available and can be found here:
