Digital protocol decoding (POCSAG/FLEX) and saving decoded messages with CC1101 in Bruce firmware
Hello,
I would like to know whether the current Bruce firmware for LilyGO T-Embed CC1101 can do more than simply detect, scan, or record RF signals.
Specifically, I am interested in whether it can receive and decode digital protocols that contain text messages.
Protocols of interest
My main interest is POCSAG, but I would also like to know about other common digital paging protocols, such as:
- POCSAG
- FLEX
- Other similar digital paging or data protocols that can potentially be received by the CC1101
Desired functionality
Ideally, I would like to be able to:
- Set the required RF frequency
- Select the appropriate modulation/protocol or reception mode
- Receive the digital transmission through the CC1101
- Decode the transmitted message
- Display the decoded text directly on the device
- Automatically save the decoded messages to a text file on the SD card
Ideally, the saved log could contain information such as:
- Date/time
- Frequency
- Pager/address/ID
- Message text
Bruce firmware support
Does Bruce currently have built-in support for POCSAG or any other digital paging/text-message protocols?
If POCSAG is not currently supported, does Bruce provide access to sufficiently low-level data from the CC1101 (for example, a demodulated bitstream) that would allow a POCSAG decoder to be implemented separately?
I would also like to understand the difference between what the CC1101 hardware is technically capable of receiving and which protocols are actually implemented and decoded by Bruce.
HackRF / PortaPack comparison
Would HackRF + PortaPack/Mayhem be a significantly better solution for this particular use case?
As I understand it, PortaPack/Mayhem already provides dedicated decoders for protocols such as POCSAG and can save decoded messages to a log file.
So, in short, I am trying to determine whether the complete workflow:
RF reception → digital demodulation → protocol decoding → displaying the text → saving decoded messages to a text file
can be implemented directly with LilyGO + CC1101 + Bruce, or whether HackRF + PortaPack would be a more appropriate solution.
Thank you!
