Overview

 

This manual is to introduce configuration when doing the instrument test.

 

1.AT commands to change to instrument test

Execute following eight commands:

 

AT+QMBNCFG="Deactivate"    // Activate previously loaded MBN configuration

AT+QMBNCFG="AutoSel",0    // Disable automatic selection function

at+qnvfw="/policyman/rat_mask",830350000000020085000000E001000021000000000000003C0A000000000000    // Set RAT_MASK value

at+qnvfw="/nv/item_files/mcfg/mcfg_segload_config",0100000002000000  //Load WCDMA mode and it should be configured to 0100000001000000 if test TDSCDMA mode

AT+QNVW=880,0,"00"   // Set to 00 if doing the WCDMA instrument test and set to 01 if connecting to base station

AT+QNVW=881,0,"00"  // Set to 00 if doing the WCDMA instrument test and set to 01 if connecting to base station

AT+QNVW=882,0,"01"  // Set to 01 if doing the WCDMA instrument test and set to 00 if connecting to base station

AT+QNVW=855,0,”01”  // Set to 01 if doing the CDMA&HDR instrument test and set to 00 if connecting to base station

 

2.Related AT commands instructions

 

2.1.AT+QMBNCFG="Deactivate"  

 

Used to delete activated configuration information. For example, if user has inserted SIM card before and activated China Mobile or China Unicom MB, this command can help to delete related configuration information.

 

2.2.AT+QMBNCFG="AutoSel",0

 

Used to disable automatically choosing MBN according to SIM card. After executing this command, inserting different SIM card won’t activate any MBN, that’s to say NV parameters won’t change because of inserting SIM card.

 

2.3.at+qnvfw="/policyman/rat_mask",830350000000020085000000E001000021000000000000003C0A000000000000

 

Configure rat_mask information. If don’t execute this command, it maybe not to connect to network in some frequency bands or standards.

 

2.4.at+qnvfw="/nv/item_files/mcfg/mcfg_segload_config",0100000002000000

 

Configure loading mode. After starting device, protocol stack will load WCDMA or TDSCDMA according to this command. Set value to 0100000002000000, it will load WCDMA; set value to 0100000001000000, it will load TDSCDMA.  

 

2.5.AT+QNVW=880,0,"00"

AT+QNVW=881,0,"00"

AT+QNVW=882,0,"01"

 

Used to choose WCDMA RRC encryption mode, set above three values to “00” “00” “01” if doing the instrument test and set above three values to “01” “01” “00” if connecting to base station.

 

2.6.AT+QNVW=855,0,”01”

 

Used to configure CDMA&HDR. Set to “01” if doing instrument test and set to “00” if connecting to base station.
