Ichnaea not fetching cells

[Phyks]

Hi,

I'm trying to get UnifiedNlp to work on my phone running Android 4.2.2. With wifi, everything is working fine with either this backend or the AppleWifi backend. However, it seems that using wifi networks for location positionning under Android 4.2.2 requires having the wifi always on, so I'm looking for a way to rely on cell network.

Using cell network in this backend, I don't get any position. After investigating it a bit in adb logcat, this line always log "Cells: 0" which seems to mean it is not fetching the nearby cells. Not sure why :/

Thanks

Title is confusing. This sounds like microg is not sending cell info to ichnaea, not "ichnaea not fetching cells"

I can confirm that the backend logs that there are no cells with wifi disabled. While running SatStat in foreground:

$ adb logcat | grep -i ichnaea
IchnaeaBackendService: Cells: 0

Edit: By setting "preferred network type" to "2G" in Settings / Network & Internet, I immediately get a location fix:

$ adb logcat | grep -i ichnaea
IchnaeaBackendService: Cells: 6
IchnaeaBackendService: request: {"radioType":"gsm","cellTowers":[{"radioType":"gsm","mobileCountryCode":262 [...]}]}
