Hi All,
We are using the PN553 for NFC with a qualcomm device host running android pie.
For our emission testing, we want to run the Switch RF Field test of the TEST_ANTENNA_CMD. But when we run the command sequence for the test we dont see the RF going on full transmit power.
The following are the commands we execute and their response -
CMD_RESET_NCI
20 0 1 0
RSP: 40 0 3 0 10 0
CMD_NCI_PROPRIETARY (enable proprietary cmd)
2f 2 0
RSP: 4f 2 1 6
CMD_SET_POWER_MODE (Disable standby)
2f 0 1 0
RSP: 4f 0 1 6
TEST_ANTENNA_CMD (RF ON)
2f 3d 5 20 1 0 0 0
RSP: 4f 3d 1 6
Has anyone run this test successfully? Is there any thing we are missing here?
Any help appreciated.
Regards,
Ashwat
Hello Ashwat,
NCI specification mandates the two commands CORE_RESET_CMD then CORE_INIT_CMD been exchange prior to any other command. Otherwise NFC Controller answers with error STATUS_SEMANTIC_ERROR. You might have noticed the last three commands all response with STATUS_SEMANTIC_ERROR(06h) in the end.
Hope that helps,
Have a great day,
Kan

Hi Kan,
Thanks for your response.
We corrected the command sequence and got the following responses -
20 00 01 01;
40 00 03 00 10 01
20 01 00;
40 01 19 00 03 0E 02 00 08 00 01 02 03 80 82 83 84 02 5C 03 FF 02 00 04 41 11 01 18
20 03 03 01 A0 B1;
40 03 07 00 01 A0 B1 02 30 02
2f 00 01 00;
4F 00 01 00
2f 3d 02 20 01;
4F 3D 05 00 AA BB CC DD
We still dont see the PN553 sending continuous RF transmission. Are we missing anything in the sequencce above?
