some weeks ago I started a similar project to PandwaRF, I have a CC1101 attached to PIC16F1455. I developed a firmware for uC, a simple USB-SPI interface with the same protocol used with CCManager (you can find it on github), and now I developing an app on android with some features as brute force and RF analyzer, and yesterday I have found this project, is fantastic. The price is very high. For me BLE and battery is useless for a similar device, I would like to find a bare version with only CC1111 and amplifiers, I hope a day you can do it. I did not understand what benefits to having bluetooth, only for rise the price. On github I see only schematics and RFcat, so this project will not open source? The app on android and the firmware on CC1111 will be closed?
I don't understand why you designed a SPI to USB interface for CC1101, rather that using the CC1111 (with built-in USB) ? Is to lower the price, which I can understand ? In this case you can use www.active-robots.com/rf-serial-data-module which is cheaper. Yard Stick One is more expensive but with power amplifiers. We also have a bare version of PandwaRF, without any FW on it, that you can program as you want. Check on our main page pandwarf.com
We added battery and Bluetooth not to increase the price :-) but to have a device that can be autonomous. The price is mainly driven by the huge efforts made on SW features. If you continue your project (and I hope you will), you will soon realize that it can be very time consuming.
Note that PandwaRF is also capable of Brute force and Spectrum Analyzer, and much more.

Right! To lower the price. On ebay you can find many breaboards with CC1101 very cheaper, about 3€, but none with CC1111, I have alot uC PIC with USB module, so was easy develope a simple firmware USB<->SPI.
