Intelligraphics has recently developed the TI WiLink 8 module family. The respective solutions are specifically created to integrate 2.4GHz and 5GHz varieties of Bluetooth 4.0 and Wi-Fi. The respective solutions offer an exquisite temperature range, as well as an unusual (so far) coexistence between Bluetooth and Wi-Fi. You can read more about WiLink here, but you should also know that WiLink 8 modules are highly indicated in automation, smart home development, entertainment, enterprise and a wide plethora of industrial applications. Another good news is that software and modules are fully compatible with old processors, so you should not make any major changes.
