Version 1.9.3

• Added auto-detection of SONOFF dongles for host software
• Fixed sniff_receiver regression setting an RSSI filter without explicitly specifying a channel
• Firmware binary distributed as Intel Hex rather than ELF or raw binary for compactness
  • Note: no actual changes to the firmware since v1.9.2, other than bumping the version

Version 1.9.2

• Implemented transmission of scannable extended advertising
• Added MAC filtering support for extended advertising
• Added proper labelling of AUX_CHAIN_IND and AUX_SCAN_RSP
• Slowed down baud rate for CP2102 based devices (_1M build variant) to 921600 to fix compatibility with non-N CP2102 variants

Version 1.9.1

• Show advertisements in addition to connect and scan requests on very slow hopping devices (like Telink devices)
• Improved AdvDataInfo decoding
• Track state changes during mark_and_flush
• Avoid unnecessary caching of extended advertising headers

Version 1.9

• Brought back measurement of advertising hop interval to support a wider range of controllers that may hop between advertising channels slower or faster than expected. This improves connection detection reliability on such devices.
• Added support for transmitting BLE5 extended advertising
• Added support for CC1354P10 Launchpad
• Added support for Sonoff CC2652P dongle and other dongles with a CP2102 USB/UART adapter that has a 1M baud limit
• Show advertisements on all three channels by hopping early if we are not trying to follow connections
• Respond to S=8 coded PHY advertisements using S=8
• Ensure AUX_CONNECT_RSP is received when AUX_ADV_IND is long

Version 1.8

• Improved connection detection reliability
• Receive, decode, and handle AUX_CONNECT_RSP
• New packet hex dump display format that is better suited for long PDUs
• Report minimum, maximum, and average RSSI for each device in scanner
• Allow specifying targets based on strings (byte sequences) in their advertisements
• Added support to act as a scannable or non-connectable legacy advertiser
• Improved receive queue flush reliability, with timestamps zeroed at sniff receiver startup
• Fixed Wireshark extcap plugin freezing and error handling/reporting
• Fixed bug sending large messages to firmware from host
• Added a UART reliability and latency test script
• Silence junk warning messages during flush
• Firmware message receive timeout for improved reliability
• Allow saving PCAPs from the scanner
• Keep bootloader "backdoor" for UART flashing enabled
• Updated to TI SDK 7.40.00.77 and UART2 API
• Built with GCC 13.2
• Briefly documented firmware APIs and transmit functionality
• Documented the XDS110 UART latency issue (that has been present for years) and a workaround

Version 1.7

• New Wireshark extcap plugin (thanks @jaylogue)
• Added support for CC2652R7, CC1352P7, and CC2651P3
• Updated for TI SDK 6.20.00.29 and TI-RTOS 7
• Added serial port auto-detection
• Added option to ignore suspected encrypted PHY changes
• Improved channel map recovery for encrypted connections
• Fixed bugs in acknowledgement and retransmit handling under master/slave operation
• Updated link layer logic to respect connSupervisionTimeout (rather than a fixed number of connection events)
• Corrected reporting of connection access address for CONNECT_IND
• Disabled RSSI filter by default

Version 1.6

• Implemented active scanning
• Sniffer now assumes advertising hop interval based on advertisement length, rather than measuring it, for more efficient and reliable advertising channel hopping
• Added option to allow preloading expected connection interval changes for encrypted connections
• Added structured reporting of measurements, such as measured connection interval for encrypted connections
• Firmware now reports connEventCount (connection event counter) to host
• Improved decoding of connection requests
• Miscellaneous minor improvements and bug fixes

Version 1.5

• Improved following of encrypted connections with parameter changes
  • Detect encrypted parameter changes based on control PDU length
  • Instahop and interval measurement to handle encrypted interval changes
  • Automatic channel map determination upon encrypted channel map changes
  • Switch to 2M PHY when an encrypted PHY change request is detected
• Distinguish between S=2 and S=8 coded PHY modes
• Added quiet mode to hide empty packets in Python CLI
• Added support for CC1352P1 Launchpad
• Fixes for slave mode operation
• Minor host-side packet decoding fixes
• Firmware updated to use TI SDK 5.10

Version 1.4

• Infer and display packet direction when sniffing
• Report PHY and packet direction in PCAP (requires Wireshark 3.4+ to decode)
• Fixed sniffing of AUX_CHAIN_IND PDUs
• Improved clock drift compensator adjustment range
• Miscellaneous bug fixes and minor improvements
• Firmware updated to use TI SDK 4.30

Version 1.3

• Basic advertiser, initiator, and master/slave link layer support
• RPA resolution using IRK (helps with frequently changing MAC addresses)
• Improved legacy advertising channel hopping connection detection reliability
• Improved communications reliability in face of CDC-ACM limitations
• Miscellaneous bug fixes and minor improvements
• Firmware updated to use TI SDK 4.10
