Had big problems with stable connection to my Autronic SM4 when I used Realdash on my track car last weekend. Did not have the same issues back in June when I used it last time.
Used my Nexus 7 2013 and lost connection all the time. Using Aten USB-serial and OTG cable.
Installed 1.7.0 on a Samsung S7 and still the same problems, but less disconnections.
Today I did some troubleshooting without car running but ignition on. Did some tests with my Huawei Mate 20 Pro and it was no dropouts. Tried with S7 and dropout came back.
Then I remembered that only difference between the phones is that I have XGPS160 Bluetooth GPS active as external GPS. And I didn’t have XGPS last time I used the car. When I removed external GPS module from the Samsung S7, connection was stable there also.
What can cause this problem? XGPS160 was not connected during the testing today because I didn’t have it. It was connected last time I used the car and had problems.
