amptone not working with QCA7500? about open-plc-utils

[lategoodbye]

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?

[n1000]

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.

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