/interface lte set lte1 modem-init="AT%CLCMD=1,1,6300,384,\"24701\",6300,385,\"24701\"" |
for Chateau LTE12
AT+QNWLOCK="common/4g",<num of cells>,[[<freq>,<pci>],...]
AT+QNWLOCK=\"common/4g\",1,6300,384
where
<num of cells>
number of cells to cell lock
<freq>
earfcn from lte info
<pci>
phy-cellid from lte info
Single cell lock example:
/interface/lte/at-chat lte1 input="AT+QNWLOCK=\"common/4g\",1,3050,448"
Multiple cells can also be added to cell lock. For example to lock to two different cells:
/interface/lte/at-chat lte1 input="AT+QNWLOCK=\"common/4g\",2,3050,448,1574,474"
To remove the cell lock use this at-chat command:
/interface/lte/at-chat lte1 input="at+qnwlock=\"common/4g\",0"
| Note |

| 1. Cell lock information will not be saved after a reboot or modem reset. 2. AT+QNWLOCK command can lock the cell and frequency. Therefore, the module can be given priority to register to the locked cell, however, according to the 3gpp protocol, the module will be redirected or handover to a cell with better signal instructions, even if it is not within the lock of the command. This phenomenon is normal. |
