Hi there, 
I try to use NTRIP on an android tablet using SW Maps. After connecting to ntrip server the quality changes to rtk float, but after 31 seconds it falls back to single. Does anybody know what that might be?

How far away is the NTRIP server/data source? Does it expect position reporting to sustain the link? ie walled garden, location based coverage or VRS

20 km. I figure out, that the NTRIP client doesn’t get any data from the server after 30 seconds. If I use Lefebure, the connection doesn’t disconnects after 30 seconds. Either way, I always receive only rtk float, also in the open air. Which correction format does the receiver need?

The Interface Description Manual describes all the RTCM3 message types it can accept. https://www.u-blox.com/sites/default/files/u-blox_ZED-F9P_InterfaceDescription_%28UBX-18010854%29.pdf

Generally you’re looking for the MSM ones, ie 1077, 1087, 1230 and 1005, with both L1 and L2 band data in them
