Have been happy Racechrono used for several years with RR trackdays. This summer I started to have issues, same phone and same BT GPS as last season...
First I noticed that the system is not recording all the laps, connection seems to work but after 10-12 laps set there is only 2 laps recorded. Then started to look more carefully about the data and noticed that my BT GPS update rate is extremely low. It should be around 10 Hz, but actual numbers are around 0.3-0.6 Hz. Last season the recording was happening more or less with full 10Hz rate. This might be reason also on the missing laps on some sessions (or might not be...).
I started to figure out if there would be any means to restore the connection by changing setting. The power saving schemes on the Android has been updated recently and I turned all the recommended settings on (Performance mode, application specific settings). This did not help on this issue. Then removed the BT pairing, re-installed the Racechrono, but not with permanent luck but with some improvement. For 2 laps the system was able to use the 10Hz again, but during the same session it did not record all laps, missed ~8-9 ones... One interesting observation, I have seen that after the new pairing is done and starting a new session and when the GPS fix is established, for short time (few seconds) the system shows 10Hz at the detailed view, but it will drop to low 0.3-0.6Hz rate. That few seconds kind of reminds me of the power saving enabling, but cannot be sure.
But how to investigate this more? Is there any ways to have some log enabled to see what is going on here? My system is Huawei Honor 8 Lite (Android version 8.0.0, PRA-LX1 126.96.36.1995(C342) build), Qstar BT-Q818XT in 10Hz mode, Racechrono Pro 6.0.8.
This is the best SW for lap timing, but this issue needs to be fixed. I can try to help by getting logs or anything else that would help if needed. Has anyone else noticed this same issue? I know that my teammate sees the same issue with different type of BT GPS and different model phone so I am not totally alone with this.
