CC2640R2F: CC3200 LaunchPad + CC2640R2F LaunchPad to replace with bluetooth smart to Wi-Fi IoT Gateway board

Hi there,

I want to complete bluetooth smart to Wi-Fi IoT Gateway 

but I don't have Bluetooth smart to Wi-Fi IoT Gateway board,

so I try to use CC3200 LaunchPad + CC2640R2F LaunchPad to replace with bluetooth smart to Wi-Fi IoT Gateway board, it's possible?

Now I build Ble-Fi Gatewaty Software(BleToWifiGateway_1.0.0) and get a blefi.bin, I flash blefi.bin to CC3200 LaunchPad, It's work.

In CC2640R2F part, what kind of SDK I can use? 

In 5.2.2 of Bluetooth® Smart to Wi-Fi® IoT Gateway User Guide, CC26xx Source Build HostTestApp example(ble_sdk_2_02_01_18), but no one for CC2640R2F.

Are there any suggestions? thanks.
