Other Parts Discussed in Thread: CC1350
Hi -
I'm using a LAUNCHXL-CC1350, and am trying to capture packets from a device communicating over 802.15.4g. I think the device I'm trying to capture uses FEC and data whitening, but I'm not completely sure yet.
I've done some work to understand the radio parameters of the target device I want to capture, and the radio channel system has the following characteristics:
- 915.0 MHz center frequency
- 64 channels
- Channel 0 @ 902.4 MHz
- 400 kHz channel spacing
- 2-FSK modulation
- 150 kbps symbol/chip rate
- Frequency Deviation 75.0 kHz
I'm trying to eventually make a system that can inter-operate with this channel system, but for right now my first goal is to be able to sniff the packets and retrieve the de-whitened data.
I made some changes to sniffer_agent_config.xml from the Smart RF Sniffer agent. I wasn't completely sure how to plug those changes into corresponding changes in the firmware. I saw another thread that seemed to give an example XML configuration file. (https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz/f/156/p/765723/2830526?tisearch=e2e-sitesearch&keymatch=sniffer_agent_config.xml#2830526)
I think I understand the changes in the XML file, but I cannot tell what firmware changes were made. I'm able to build the firmware, and using Smart RF studio, I exported configuration files (in .c and .h) and have imported them into my CCS project. But I'm unsure how to make Smart RF Sniffer and the firmware cooperate.
Is there any documentation I can reference on how to get packet sniffing that matches my required parameters?
Thanks in advance.
