Issue F9P UBX-RXM-MEASX

0 votes

Hello,

I had for what ever reason UBX-RXM-MEASX-Uart1 enabled and had in RTKLIB messages  0x02 0x04.

When looking in the F9P interface description, i see this: 5.15.1 UBX-RXM-MEASX (0x02 0x14).

It took a while to realize that this was the RXM-Meas : When I switch UBX-RXM-MEASX-Uart1 off the messages 0x02 0x04 (1492length) disappear.

Is this a bug in the docu or in the firmware ? I use HPG 1.10

I am aware that RXM-MeasX is not very usefull, but I was hunting unnecessary messages to reduce bandwidth and was not able to find the switch for them.

so long

Are you sure it is decoding the messages properly? UBX-RXM-MEASX enabled on uCenter only yields 0x2 0x14, 1468 bytes in test on ZED-F9P here.

Hi Clive,
you are right.
There is a third option for the error : RTKLIB  is showing 0x02 0x04 instead of the right message header.
All versions 2.4.3 seem to do so. Haven't checked 2.4.2

Many thanks,
