ST67W61 pass-through mode

Hello,

does ST67W61 module support pass-through mode?

 

I have an application based on a third-party IP stack and it would be a pain to rewrite it all with AT primitives.

A far simpler solution would be replacing low-level calls to transmit and receive Ethernet frames over SPI link.

Hi Alessandro,

The only interface available between the ST67W611 and the Host is AT commands over SPI.
