Replacing MRF24WG0MB with ATWINC1500

We have a product that has been using MRF24 Wi-Fi modules for around 9 years. It appears that our supplier is finding the MRF24WG0MB is not so easy to procure these days. We are looking at replacing it with the ATWINC1500, and I'm hoping to avoid the Harmony path. Our system uses a PIC32MX795F512L and it is still being built in C32 1.12 from MPLAB 8.92. From some other discussions in this forum, it appears that you can still use the last (2018) Microchip MLA for the ATWINC1500, but I'm hoping someone with more experience here can confirm that this is still a good approach. We have 2 code builds that use the MRF24 as 1) a client for TCP socket transfers, and 2) a soft AP host with HTTP support to connect to tablets. Any advice on this shift to ATWINC1500?

    I don't see any PIC32 projects for the WINC1500 in the latest MLA.  Only 8/16-bit.

    It should be possible to adjust it to work with PIC32 though, right? Less work than porting the whole rest of the code (including cell communication) to Harmony, maybe?

    I would think it would be as straightforward as redoing the SPI interface.

    I think I will give that a try first then, thanks. I ended up making a number of alterations to the MLA code for the MRF24 to make it fit into my application anyway.
