2 NCI Wrapper FTM Functions
This chapter describes QRCT procedures for NCI wrapper FTM commands. These NCI wrapper
functions consist of methods for routing NCI packets between the host PC and the NFCC.
This includes:
 NFC FTM setup
 Sending any NCI Command and getting the NCI Response
 Sending a Sequence of NCI commands with text files
 Getting NCI Notification packets

QMSL header files for Connectivity can be found in
C:\Program Files (x86)\Qualcomm\QDART\QMSL\inc\inc\QMSL_Connectivity
Usage of these NCI wrapper commands requires a high level of familiarity with the NFC Forum
NOTE:
NCI standard. To make testing easier, high level NFC FTM functions were developed that use the
NCI wrapper functions in specific sequences internally. The high level NFC FTM functions are
described in Chapter 3.

2.1 General QRCT procedure for NFC setup
Table 2-1 QRCT steps to perform NFC setup
Step QRCT procedure – NFC Setup QMSL equivalent
This instruction is for Android platforms only. Other HLOS may have a
1.
functional equivalent.
On the phone GUI, disable the NFC service in Android Wireless &
Networks setting on the Android target.
This is to prevent the phone’s processor from acting as the DH for NFC.
Instead the tester PC will act as the DH with NCI messaging sent via
FTM diag packets.
This instruction is for Android platforms only. Other HLOS may have a
2.
functional equivalent.
Execute the ftmdaemon in the Android target. From a cmd shell, execute
the following commands
adb root
adb shell /system/bin/ftmdaemon -n (some targets may not require the –
n parameter)
3. Start QRCT. Under the Target menu, select the appropriate target type; QLIB_SetTargetType( 0
MSM/MDM or APQ. );
// MSM/MDM
or
QLIB_SetTargetType( 1
);
// APQ

4. Select QMSL Library Mode. Use QPST if it is installed. Otherwise select QLIB_SetLibraryMode( 1
QMSL Internal (QPHONEMS) );
// QLIB_LIB_MODE_QPST

or

QLIB_SetLibraryMode( 0
);
//
QLIB_LIB_MODE_QPHONEMS

5. Click the COM Port button to scan COM ports. QLIB_GetAvailablePhone
Then click the drop down list next to the COM Port button and select the sPortList()
desired port to connect to the phone. QLIB_ConnectServerWith
Wait(
COM13,2000)

Note: If the device’s port does not show up, and QPST is being used,
then check QPST Configuration to see if QPST detects the device and
has the port enabled.

6. Select FTM Command →NFC

7. Enable NFC log packets by clicking the Enable Logs button. This only QLIB_FTM_NFC_EnableLog
needs to be done once. s( HANDLE

8. One could start from a known state by sending the Core Reset NCI Core Reset
command followed by the Core Init command.

see parameters for
QLIB_FTM_NFC_NFCC_CM

in paragraph 2.2
(the values shown above are
for parameter
pNfc_nfcc_cmd)

2.2 Sending any NCI command and getting the NCI response
Any NCI command can be sent from the host PC to the NFCC within the DUT by wrapping the
NCI command packet within a (FTM) diag request packet.

Factory Test Mode Procedure for NFC Test Application Note NCI Wrapper FTM Functions

The corresponding NCI response packet will sent by the DUT back to the host PC wrapped
within a (FTM) diag response packet.
This is done with QMSL function QLIB_FTM_NFC_NFCC_CMD_RSP.
Table 2-2 QRCT steps for NCI command - response

Step QRCT procedure – NCI Command - Response QMSL equivalent
1. The NCI Command-Response section in QRCT can be used to send unsigned char
any NCI command and get the corresponding NCI Response. QLIB_FTM_NFC_NFCC_CMD_RSP(
Simply type the NCI command packet in the text input section and HANDLE hResourceContext,
click the Send NCI cmd button. unsigned short
Enter the byte sequence in hexadecimal format, 2 characters per Nfc_nfcc_cmd_len,
byte, with a single space between each byte, as in the example unsigned char*
below. pNfc_nfcc_cmd,
QRCT will decode the NCI command and response type from the first unsigned short*
2 bytes of each command/response and display it below the raw pNfc_nfcc_rsp_len,
bytes of the packet. unsigned char*
pNfc_nfcc_rsp );
