Hello all,
we are in the same situation and we have the same question but 4 years
later... Are there new ideas and/or solutions?
I have been using MXCHIP EMW3165 modules with LwIP. Those modules have
Cypress Semiconductor CYW43362 (previously broadcom BCM43362) wifi chip on them. The WICED SDK for those no longer has LwIP, but it is possible to use only wifi driver layer from it with any stack. Module costs only $4.49, and one gets a STM32 + flash chip on it too. There is also a ready-made breakout board for prototyping called "WifiMCU", for
about $10.

I have a couple of those modules running with LwIP 2.0.2, they work very well.

If I remember correctly there are other modules using the same wifi chip, but they are more expensive and don't include application MCU. But those might be
useful if you want to use something else than STM32 on this module.

The stuff I use to build the driver from SDK is here:

in case someone is interested. LwIP driver source is in wlan_if.c.
