Trouble with cell-based location on ELS61 | Thales IoT Developer Community

January 26, 2020 - 3:51pm, 1492 views

Hi,

I am trying to get neigborhood cell information from the ELS61 (via AT commands) to use with cell-based location services (Google Geolocation, etc). 

So far I have been able to find the following relevant entries, none of which seem to help:

https://iot-developer.thalesgroup.com/threads/ehs6-localization-gsm-cells

https://iot-developer.thalesgroup.com/showcase/cell-id-based-positioning...

https://iot-developer.thalesgroup.com/threads/cell-tower-triangulation

In my experiments on 4G, both SNMON and SMONP *always* return empty lists for the neighbor cells. If I use COPS,2 to unregister and then execute SNMON="NBC",2 the modem returns an error "Operation not allowed". So I have not been able to find any set of AT commands that does the job.

Is there a set of AT commands that reliably returns a list of neighbor cells on 2G, 3G, and 4G networks? (if I have to unregister from the network during the scan then that's not ideal but acceptable)

Thanks,

-- Terrence
