The gpsmodul is from Navspark and the output is not equal NMEA .
Sample: $GNRMC but not $RMC.
The libraries TinyGPS++ and TinyGPS can not work with the output.
Hello. @lukasmaximus
Thank you for answering.
I used the firmware when I purchased M5GO.
By using the Japanese manual that you taught, I was able to check the operation in UIFlow.
I did not know that M5GO WebIDE can not be used.
I will use UIFlow or M5Cloud in the future.
The coding platforms you can connect to (m5go, m5cloud, ui flow) depend on what firmware you have burned
on your device. For example if you have m5go firmware you cannot connect to the ui flow site with it.
