Hi,
I have a EVB-LIV4F. I would like to know how to enable RTCM message. I would like to extract the following raw measurements from RTCM:
1) the time of the measurement
2) satellite pseudoranges measured between the satellite and GNSS receiver
3) their standard deviations
4) carrier phase
5) Doppler shifts
Thanks.

Thanks @patrikpordi for sharing your code! Appreciate your help.
pyrtcm works for me
rtr = RTCMReader(stream)
raw_data, parsed_data = rtr.read()
if parsed_data is not None:
print(parsed_data)

Also, I am able to get GxGST message in the standard firmware. Once I load ME firmware, I don't receive GxGST message. Is it possible to enable GxGST message in ME firmware?
Thanks.

Hi Koon,
I am not sure if you found the answers you were looking for.
To get information from Measurement data you can use CONVBIN tool provided as part of RTKLIB release. This will convert RTCM3 data into RINEX format.
Attached is the snippet I used as an example.
I saw in another post that GST message is not available.
In our ME binary, we output Kalman Filter Covariance information.
This is a new feature so LIV4F manual is not updated yet. Please let me know if this would suffice.
To enable PSTMKFCOV message, do the following
$PSTMSETPAR,1201,0x8000000,1
$PSTMSAVEPAR
$PSTMSRR
