  • Added a firmware version check utility
  • Fixed hang stopping extcap in Wireshark on Mac
  • Fixed auto detection of CP2102 non-N Sonoff dongles
  • Removed -m top feature from sniff_receiver; use the MAC, IRK, or string search features to select a target instead

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

Compare
Choose a tag to compare
  • 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

Choose a tag to compare
  • 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

Compare

  • Added structured reporting of measurements, such as measured connection interval for encrypted connections
  • Firmware now reports connEventCount (connection event counter) to host
