Cockpit v8.3.0 encounters an 'invalid NCI packet' issue when used with the PN7220

[chiajeng]

Hi Sir,

When using Cockpit v8.3.0, we encountered an issue on the DPC tab:
after clicking Start Calibration, Cockpit sends an invalid NCI packet during communication with the PN7220, which causes the entire Cockpit application to crash.

The behavior is shown in the attached screenshots.
May I know how we can resolve this issue?

Device Information

• PN7220 upgraded to 3.2.4 firmware to meet Cockpit v8.3.0 requirements

Host Information

• OS: Android 13

• pnscr: NNC_uC_ADBSocket_06.00.00

Thank you.

Hello @chiajeng 

PN7220 NFC front-end = same as PN5190 front-end, Correctly using the table “DPC” of NFC Cockpit 8.3.0, please check the Training video:

HI @KaiLi

We are familiar with how to use Cockpit and the DPC feature.

The current issue is that when we execute Start Calibration on the DPC page, communication with the PN7220 eventually causes the entire Cockpit application to crash.
From the PNSCR logs, we can see an invalid NCI package.

We can use Cockpit v8.1.0 together with Firmware v3.2.2 without any problems.
