Working NRF and BTLE decoders with the following limitations:
- The NRF24L01+ protocol decoder is missing 0/1 byte CRC and fixed length packages. Both should be trivial to implement, please open an issue if you need that capability.
- The BTLE protocol decoder currently supports only advertisement packets on channel 38 and not data packets / frequency hopping. I am still evaluating whether the rtl-sdr hardware is fast enough to track the frequency hopping.
