amptone not working with QCA7500?

[kultate]

Hi,

I have been using amptone succesfully to measure signal quality with QCA7420 based adapters. I would like to make similar measurements with a QCA7500 based adapter, but amptone gives me an error:

$ amprate -i eth0 -rn eth0 00:B0:52:00:00:01 Request Version Information eth0 F4:06:8D:AD:2C:09 QCA7500 MAC-QCA7500-2.2.1.770-00-20160307-CS eth0 F4:06:8D:AD:2C:09 F4:06:8D:AD:2B:48 TX 611 mbps Alternate eth0 F4:06:8D:AD:2C:09 F4:06:8D:AD:2B:48 RX 741 mbps Alternate $ amptone -i eth0 -s F4:06:8D:AD:2C:09 F4:06:8D:AD:2B:48 amptone: Too many carriers: Value too large for defined data type $

Is there something that I could do to make amptone work with QCA7500 chipset?

Thanks!

Hi @kultate, you could try plctone but it's possible this chipset isn't implemented yet.

Okay, i can confirm that ToneMaps2 and SignalToNoise2 can't handle the QCA7500. The MME response seems to be different.

@n1000 Any plans to fix this?

I don't have the documentation that covers the new PIB / Prescalar format for the QCA7500. I'll look into what it would take to make this information available.

[n1000]

I was apparently confused when I posted my last comment, as this question is not about PIB / Prescalar format, but rather about the SNR / modulation rate per subcarrier. I'll have to look into this further.

I have the same problem. Tried with a TP-Link PA8010P (QCA7500), and both amptone and plctone is not able to read due to " Too many carriers: Value too large for defined data type"

Interesting is, int6 tool can read various parameters, and can read tones up to 916 tones:

Would be nice to make this work. There are quite a lot of powerline devices out there with this chipset.

Some more info:

I can provide the PIB files also, if someone is interested about it.
