So I've got both the MultiNav Pro+ BLE module and the GNSS module running on the same custom carrier board and I'm starting to wonder if they're stepping on each other. GNSS reception seems noticeably worse when BLE is actively transmitting - like I'll go from a solid fix to getting jumpier position readings, and I don't think it's multipath because it's pretty consistent and repeatable indoors vs outdoors doesn't really change the pattern. The BLE module's RF front-end is obviously doing some serious work given the 50km range spec, so I'm guessing that's not a quiet neighbor to have sitting near a GNSS receiver.
