When using the L76X module (in my case, the L76K is mounted), the device cannot be configured with the supplied code. The main error is the usage of the PMTK-Commands whereas the PCAS command format has to be used (see https://www.waveshare.com/wiki/L76K_GPS_Module or https://www.waveshare.net/w/upload/d/dd/Quectel_L76K_GNSS_Protocol_Specification_V1.1.pdf). The wrong definitions can be seen in l76x.py, line 36 to line 82.
