Hi,
Product code looks like this RUT950H*****. The 7th symbol defines the LTE module. H means it has a Quectel LTE module.
If you got a device with a product code like this you can follow this instruction:
Please follow these steps for a bandlock via SSH:
1. Stop mobile data connection:
ifdown ppp
2. Select desired bands:
gsmctl 'AT+QCFG=“band”[,<bandval>,<ltebandval>,<tdsbandval>[,<effect>]]'
<bandval> A hexadecimal value that specifies the GSM and WCDMA frequency band. If set
<bandval> to 0, it means not to change GSM and WCDMA frequency band. (eg.: 00000013=00000001(GSM900)+00000002(GSM1800)+00000010(WCDMA2100))
00000000 No change
00000001 GSM900
00000002 GSM1800
00000004 GSM850
00000008 GSM1900
00000010 WCDMA 2100
00000020 WCDMA 1900
00000040 WCDMA 850
00000080 WCDMA 900
00000100 WCDMA 800
00000200 WCDMA 1700
0000FFFF Any frequency band
<ltebandval> A hexadecimal value that specifies the LTE frequency band. If set <ltebandval>
to 0 or 0x40000000, it means not to change LTE frequency band. (eg.:0x15=0x1( LTE BC1)+0x4( LTE BC3)+0x10( LTE BC5))
0x1 (CM_BAND_PREF_LTE_EUTRAN_BAND1) LTE BC1
0x4 (CM_BAND_PREF_LTE_EUTRAN_BAND3) LTE BC3
0x10 (CM_BAND_PREF_LTE_EUTRAN_BAND5) LTE BC5
0x40 (CM_BAND_PREF_LTE_EUTRAN_BAND7) LTE BC7
0x80 (CM_BAND_PREF_LTE_EUTRAN_BAND8) LTE BC8
0x800000 (CM_BAND_PREF_LTE_EUTRAN_BAND20) LTE BC20
0x1a0000800d5 (CM_BAND_PREF_ANY) Any frequency band
<tdsbandval> A hexadecimal value that specifies the <tdscdma> frequency band. If set
<tdsbandval> to 0 or 0x40000000, it means not to change TDS-CDMA frequency band. (eg.: 0x21=0x1( TDS BCA) +0x20( TDS BCF))
0x1 (CM_BAND_PREF_TDS_BANDA) TDS BCA
0x2 (CM_BAND_PREF_TDS_BANDB) TDS BCB
0x4 (CM_BAND_PREF_TDS_BANDC) TDS BCC
0x8 (CM_BAND_PREF_TDS_BANDD) TDS BCD
0x10 (CM_BAND_PREF_TDS_BANDE) TDS BCE
0x20 (CM_BAND_PREF_TDS_BANDF) TDS BCF
<effect> When to take effect
0 Take effect after UE reboots
1 Take effect immediately
Example:
gsmctl -A 'AT+QCFG="band",0,40,0,1'
3. Start mobile data connection:
ifup ppp
Additionally:
To read used frequencies:
gsmctl -A 'AT+QCFG="band"'
+QCFG: "band",0xd3,0x40,0x0
To read used frequencies in words format:
gsmctl -A AT+QNWINFO
to set exact bands:
gsmctl -A 'AT+QCFG="band",0,40,0,1'
OK
Multiple frequencies at one time:
It's not force one band, when you use AT+QCFG="band" and set
any combinations of band you need to use, for <ltebandval> 1800 is band 3,
and it's config is 4, and 2600 is band 7, it's config is 40, so you sum this
two and it will be 44, so you need to set <ltebandval> as 44.
Any frequency:
0x1a0000800d5
