Hi,
I just started porting the ANTFS example to a PIC18(XLP)-based project, and ran into the following issue. Within antfs.c there is the following:

///////////////////////////////////////////////////////////////////////

// Decode Transport Commands

///////////////////////////////////////////////////////////////////////

static void DecodeTransportCommand(UCHAR ucControlByte_, UCHAR *pucTransCommand_)

{

   ...

      case ANTFS_CMD_LINK_ID:

      {

         ULONG_UNION uHostSerialNumber;

         uHostSerialNumber.stBytes.ucByte0 = pucMesg[HOST_ID_OFFSET_0];

         uHostSerialNumber.stBytes.ucByte1 = pucMesg[HOST_ID_OFFSET_1];

         uHostSerialNumber.stBytes.ucByte2 = pucMesg[HOST_ID_OFFSET_2];

         uHostSerialNumber.stBytes.ucByte3 = pucMesg[HOST_ID_OFFSET_3];

         ...

...however, I can't find any definition of (uchar*) pucMesg, and neither can the compiler. Should this be referencing (uchar*) pucTransCommand_ instead?

Thanks!

Are you using the latest version (1.1.0) of the embedded reference design?

Hi Alejandra,
The code I'm using is from the ANTFS_EMBEDDED_CLIENT.zip file, downloaded on 2/18 or so. It doesn't state a version number, but the file size matches the one currently posted (80989 bytes).

Hi,
I ran into another suspicious bit of code: at line 1187 or so of antfs.c, there is:

if(ucControlByte_ & SEQUENCE_LAST_MESSAGE) // last packet
{

if(PAIRING_AVAILABLE_FLAG_MASK)
{
...

which generates a compiler warning ("condition always true") because PAIRING_AVAILABLE_FLAG_MASK is a bitmask set at compile-time. Is this really meant to test that the mask constant is defined/nonzero, or should this be testing if(some_status_byte & PAIRING_AVAILABLE_FLAG_MASK) ?

Thanks!

The compile problems you see are not present in version 1.1.0. Please make sure to use the latest version from the website. Most of our software releases have a version.h file with the version, in case you are unsure you have the right one.

Regarding the pairing flag mask, you are correct, the code should be checking for stActiveBeaconStatus1.bPairingEnabled.
