ST8500 FSK modulation

[RiccardoP]

Hi, I am evaluating to use the ST8500 module as alternative part of the ST7538Q.

In our application we have a custom protocol over power line with FSK modulation.

Looking all the documentation related to ST8500 I found that it is possible to configure the carrier frequency, the bandwidth and the modulation as the ST7538Q. 

The point that for me is not clear is about the RTE and PE images to be downloaded on the IC. All the documentation is related to the G3 protocol and also the images are related to this protocol. In case I would like to use only the PHY layer without the other layers of the stack, is it possible to create a light version of these images ? Or the images have to be provided by ST?

Moreover should I use the G3-lib as host interface driver?

Hi Riccardo, 

The G3 stack allows you to connect your application to the Physical layer thanks to the Service Access Point. 

We are not generating light version of these images, only the full stack is provided where the user connects its application to the needed layer. 

About the G3-Lib, I can invite you to enter an OLS ticket on ols.st.com and inform the ST8500 product in the OLS. 

Best regards,

Thank you for the answer, I will contact OLS for the G3-Lib.
