pn7150 self test

[normbxl]

Hello,

I've tried to use the test-antenna feature of the PN7150 (chapter 12.3 in user guide) but the controller returns a status=0x06, which is not defined in the list of possible status values. In other cases the 0x06 would stand for a semantic error, but I can't see why.
The code for reading the TxLDO current

uint8_t testTxLDO_Cmd[] = {0x2F, 0x3D, 0x02, 0x01, 0x80};

uint8_t response[MAX_NCI_FRAME_SIZE];

uint16_t respLen;

NxpNci_HostTransceive(testTxLDO_Cmd, sizeof(testTxLDO_Cmd),

            response, sizeof(response),  &respLen);

if ((response[0] != 0x4F) || (response[1] != 0x3D) || (response[3] != 0x00)) {

   return NXPNCI_ERROR;

}

float I_txLdo = 0.4f * (float)response[4] + (response[5]==0 ? 50.0f : 20.0f);

response[3] is in my case 0x06. Same is true if I use the function NxpNci_FactoryTest_RfOn() from the new Nxp-Library, where basically only the command and parameter is different (0x20, 0x01 at the end).

Has anybody had success using the self-test?

Hi Norman,

Is it possible to share the NCI log of this issue? Thanks for your patience!

Have a great day,
Kan

Since the old buggy library code destroyed the EEPROM of the NCI on the development board I'm using the NCI on the board designed by us, meaning I don't have a full log like the console print from the example.
I can tell that the response array on the self-test request look like this:
[x4F, x3D, x01, x06] with response-length 4. Since the first 2 bytes just show that this is a reply to command x2F, x3D and byte 3 is the length of the response (1) the 4th byte is the status and should be 0x00 if everything went fine.

Hi Norman,

Thanks for the information! Would you please help to check the Manufacturer Specific Information in [NCI] CORE_INIT_RSP on your side? We may have the firmware version info from this. Please kindly refer to the following for details.

Thanks for your patience!

Have a great day,
Kan

Hi there,

We are experiencing the exact same issue as Norman, the TEST_ANTENNA_RSP being 0x5 or 0x6.

Our CORE_INIT_RSP is in hex:

40 1 19 0 3 1e 3 0 8 0 1 2 3 80 81 82 83 2 d0 2 ff 2 0 4 88 10 1 a0

Thank you for your quick help

Hello Kan,

here is a screenshot of the full 28 bytes of the CORE_INIT_RSP:

HW_Version= 64
ROM version=1

FW version = 25.0
