At our company, we included the L76-LB GNSS module in one of our designs. Our provider gave us two options for firmware: L76LBNR03A01S_GLN (GPS + GLONASS) and L76LBNR03A01S (GPS + Beidu). According to the Quectel support team, none of these versions support I2C communication which we need, but L76LBNR03A02SC supports it. In the documentation I have (Quectel_L76-LB_╚Ý╝■░µ▒¥▒õ©³╦Á├¸_V0302SC.pdf in Chinese, provided by the Quectel support team) there’s nothing related to the positioning technology supported by this firmware version (GPS + ?). Could anyone please tell me where I can find more detailed information about the L76LBNR03A02SC firmware version and the firmware updating procedure?
