LC29H Binary Raw Measurement

In Quectel_LC29H_SeriesLC79HAL_GNSS_Protocol_Specification_V1.2.pdf the command “830 PAIR_RAW_ENABLE” is described as “Enables/disables outputting binary raw measurement.” However this protocol doesn’t seem to be documented. Could I get documentation for this, in particular option 2 which includes SV and PVT information?

Hi Luke,

I guess you need binary protocol which reports GNSS raw data. You need to send PAIR432 command to enable RTCM output. And please refer to supported RTCM protocol. You will have an official protocol from https://www.rtcm.org/.


Best regards.

The binary protocol that this enables matches with the MTK binary format that I’m finding referenced online. It looks like Airoha kept at least the header (0x04 0x24) and footer values (0x0D 0xA).

There are references to this binary format in the Quectel EPO documentation; but I’m very interested in the SV and PVT information that gets turned on by the $PAIR830,2*2F command.

SV information is not included in the RTCM protocol messages that are produced by the Quectel firmware, so I’m hoping that this can work for my application.

Hi Luke,

Can you tell me which kind of binary protocol you need?

Best regards.
