We have just released details of our GollumRF platform on hackaday.io
GollumRF is the bridge between smartphone and other wireless objects transmitting in the sub-1GHz RF band, like garage door receivers, car keyfobs, roller shutters, fire detectors, etc…
All these devices often use custom RF transmissions, but with GollumRF built-in CC1111 Sub-1 GHz RF Transceiver, you can receive and transmit data in the ISM band at 315/433/868/915 MHz.
With GollumRF BLE chip, these data can now be directly sent to your smartphone, which will display binary data or spectrum analysis of a RF transmission.
GollumRF also has a dual JavaScript and Python scripting feature, giving you the ability to dynamically control the RF, for both TX and RX, without any SW rebuild.
