cell lock on CHATEAU LTE12 - output error

RouterOS Beginner Basics
1

Super newbie here.
I have been using for a year a CHATEAU LTE12 without problems. Excellent modem/
I have been running RouterOS v7.2.3 and LTE modem Model EG12-EA with fw EG12EAPAR01A11M4G

I want to lock my CHATEAU on the specific cells (see screenshot)
Primary Band B7@20Mhz earfcn: 3050 phy-cellid: 438
CA Band B3@20Mhz earfcn: 1700 phy-cellid: 438

When i enter the following command i get output error

interface/lte/at-chat lte1 input=“at+qnwlock=“common/4g”,1,3050,438”
output: ERROR

When i type for example the following (which to be honest i have no idea what it does, it seems like a help command?) i do get a response

[admin@MikroTik] > interface/lte/at-chat lte1 input=“at+qnwlock=?” wait=yes
response:
output: +QNWLOCK: “common/4g”,,[[,],…]

What am i doing wrong?

I guess you have to escape the inner quotes:


/interface/lte/at-chat lte1 input="at+qnwlock=\"common/4g\",1,3050,438"

one additional info.

/interface/lte/at-chat lte1 input=“at+qnwlock="common/4g",1,3050,438”

Cell Lock to 1 specific tower & “antenna”


/interface/lte/at-chat lte1 input=“at+qnwlock="common/4g",2,3050,438,1700,438”
/interface/lte/at-chat lte1 input=“at+qnwlock="common/4g",2,1700,438,3050,438”

Remember that order is not important and both command do the same. Module select one with best signal and that start to be primary-band. When you put more “CellLocks” then you not know with one it will be connected, the signal is a selector here.

You can select by Cell Lock the Primary band, but all other CA are automatically. Only limiting the active bands can do some help to select proper ca.

stupid me. Thanks a lot guys. Cell lock is successful now.
And SIB thanks for the extra info regarding carrier aggregation.

One more question. Is the cell lock still valid in case of a reboot on the CHATEAU ?
