Problem with SMAC, MC13213 and single port

[yb]

Hi,

I try to use a MC13213 in single port mode.

I generated a CW project with BeeKit for a NCB board (not mine ; I use a custom board).

I read the AN3248 and changed the value of the 0x07 modem register (0x5C00 instead of 0x4C00).

My board doesn't receive or transmit nothing (the code is running on 13192EVB and SARD board on same time).

Any ideas ?

Regards,

Yvan

The main problem here is that the NCB and SARD circuitry are not designed for SINGLE PORT mode, try a PAN4555etu from digikey to test SINGLE PORT mode.  The NCB has an external switch that would inhibit use of the internal switch.  And I think the SARD would have problems with the CT_Bias functionality using the PCB Dipole.

Once you get the hardware I think you'll be set...  You have enabled the right bit (bit 12 - cRF_SwitchMode), but you need to make sure it stays set (see "MacPhy\Phy\PhyMain.c").

If you haven't already, you might want to check the Rx/Tx Antenna switch settings ( see http://forums.freescale.com/freescale/board/message?board.id=8BITCOMM&message.id=6780#M6780 or http://forums.freescale.com/freescale/board/message?board.id=8BITCOMM&message.id=8743#M8743 )
