TagWriter can not read the PN7160 tag

[BillyHu]

I am running the RWandCE example（LPC55S69+PN7160）. When I use the TagWriter app on an Android phone to read the tag, it fails with no response. The log shows that it activated the poll mode. However, TagInfo can read it, but it shows a "communication interrupt" popup, and the result on the phone may be incorrect. Is this because both poll and listen are enabled in the discovery loop? But my requirement is that both poll and listen must be enabled simultaneously. And  I have also closed all emulation cards on my android phone.

Please help me, thanks.

Hello @BillyHu

Hope you are doing well.

Please try updating PN7160 FW to the latest version available .You can refer to PN7160 - FW Update via MCUXpresso for more information on this.

Dear Eduardo,

Do you have any suggestions? Is this phenomenon normal for the PN7160?

Thanks,

Hi Eduardo,

My firmware version is already 12.50.11. Poll and listen work perfectly fine when used individually, but when both are enabled in discoveryTechnologies, I cannot read the card emulation of the PN7160 using the tagwriter. Have you encountered this issue on your side?

Thanks,
