NFCPlayer on MSP430F5529 LP + TRF7970A BP = "NFC: Technology removed" message + stop working after a while

Other Parts Discussed in Thread: MSP430F5529, TRF7970A

I'm using NFCPlayer 1.0.153.5 on a MSP430F5529 LP + TRF7970A BP.

Everything runs fine: I can read and write tags.

However, after a while, a blue message appears NFC: Technology removed and no more tag is read.

I went through the Troubleshooting Tips of the RFID BoosterPack TRF7970A BP With MSP430F5529 LaunchPad (PPT) (SLAB069) document, to no avail.

What's going wrong? Is the software time-limited?

Thank you!

Hi,
my suggestion is that you download and run DebugView: https://technet.microsoft.com/en-us/library/bb896647.aspx

It will log a lot of stuff from the NFC stack. Make sure that the trace flags which are configurable through the GUI are set to the default values. If you didn't touch them, everything should be okay.

The log will probably help to root-cause your issue.
