Lock mobile to ARFCN

I'm working on a project which I want to control a Qualcomm chip-set mobile with AT-commands.

I made some initial progress with the supported AT-commands, but found out that these are very limited in getting the Informations we are interested in.

The only thing I got stuck with: I can't figure out how to lock the mobile to a given ARFCN.

Is there a hidden AT Command, or do I have to send a specific command to the Qualcomm Diagnostics port?

Solution

  • I’m afraid there is no way to set particular ARFCN via AT on ‘non-dev’ soft. However, you can try to manipulate with NV items on your Qualcomm device (I set bands via QXDM on various commercial LTE devices).

    You can also change NV items via DIAG. This can be helpful - DIAG_QCDM
