i testet two new CubeCell GPS Boards V1.1!
I had some problems with one CubeCell GPS Board V1.1!
I programmed both boards with the example programm oledDisplayGPSInfo with modification in setup: Air530.setmode(MODE_GPS_GLONASS);
Arduino-IDE 1.13; CubeCell Framework 1.2
One modul had a GPS-Fix after ca. 5 minutes!
The other modul get a fix after ca. 15 minutes (same outdoor position) and, that is surprising, the red LED (serial connection?) flickers very quickly and can hardly be recognised at daylight.
The other module does not!
Both modules powerd by USB-Powerbank!
What is wrong with one module HTTC-AB02S?
I can’t detect any red LED in Schematic V1.1:
