Hello Nordic Support,
I am developing a cellular positioning solution using an nRF93M1 LTE Cat 1 bis module.
I currently use the following command to retrieve the serving cell and neighboring-cell measurements:
AT%BCINFO=3,20
The command provides:
- EARFCN
- PCI
- RSRP
- RSRQ
- MCC/MNC
- E-UTRAN Cell ID
- TAC
However, it does not appear to provide the LTE Timing Advance for the serving cell.
On the nRF91/nRF91x1 family, the %NCELLMEAS response includes a
<timing_advance> field and its measurement timestamp. I could not find an
equivalent documented command or response field in the current nRF93M1 AT
Commands Reference Guide.
Timing Advance would be useful for improving third-party cellular positioning
requests, for example when using APIs that accept the serving-cell Timing
Advance in addition to ECI, TAC, PCI, EARFCN, RSRP, and neighbor measurements.
Could you please clarify:
1. Is the serving-cell Timing Advance currently available through any nRF93M1
AT command or diagnostic interface?
2. If not, is support planned for a future nRF93M1 module firmware release?
Thank you
marco
