telegram received but incomplete or with errors, since rtl_wmbus reports that CRC checks failed

[geogeozib57]

Good morning ,

I installed wmbuslmeters on a raspberry pi 3 b+, the whole installation went well but when I try to capture my water meter I have the following message:
"telegram received but incomplete or with errors, since rtl_wmbus reports that CRC checks failed"
, my meter is of the "DIEHL" brand and the transmission frequency is 169 Mhz.
Thank you in advance for your help.

no one has any ideas?

You can search issue archive - this topic has been discussed at least few times. Here are few topics about antennas.
So basically try moving closer to meter and check if CRC issues disappear. That is usually due to lost message frames during reception.

thank you for your answer, I have already tried to bring the antenna closer but the result is the same.

It might also be that the meter transmits on 169MHz and on this frequency the modulation is called n-mode.
rtl-wmbus does not support n-mode telegrams. The dongle amb3665-M does though.

yes indeed it is on the 169mhz frequency, so the only way is to have an amb3665-m dongle or with those it is possible that it works?
