Since STA8135G is a triple-frequency GNSS chip, its hardware should have the capability to decode the E6 HAS message. However, I can't find related message from its RTCM output.
I have searched the web and was informed that it can be supported by upgrading to certain firmware, named Measurement Engine (ME) Firmware.
Can anyone help to tell me where I can find the suitable firmware, and whether I can do the upgrading and make my chip a more precise one?
