Current Stable Versions

Device	Version
ConBee II	0x26680700
RaspBee II	0x26690700

Device	Version
ConBee I	0x26390500
RaspBee I	0x26390500

Note: The number differences between I and II series don't represent feature or bugfix equality as there are different underlying Zigbee stacks in use.

ConBee II and RaspBee II (R21)

• 0x26710700 Beta 2021-08-18
  • This version is for RaspBee II and includes all changes from 0x26710700.
  • Improved stability of the UART communication.
• 0x26700700 Beta 2021-08-11
  • This version is for ConBee II only
  • Fix loopbug behaviour caused by a USB stack bug.
  • Force end-device to MAC poll once more by using the MAC layer frame pending flag
  • Improved serial communication performance.
  • ZCL Default Responses for ZCL profile wide commands, e.g. attribute reports, and IAS notification status change commands are now handled directly by the firmware. This prevents devices from becoming lost when no host application runs, e.g. after a restart.
    Note: Projects which use the serial communication protocol don't need to change anything — the firmware replies with APS confirm status = success for ZCL Default Response commands sent by the host application, if they were already handled.
  • The maintenance of directly connected end-devices was improved.
• 0x266f0700 Beta 2021-07-13
  • Allow sending custom Node Descriptor response from the application (since deCONZ v2.12.2-beta).
  • Set 'End device Timeout Request Keepalive' flag (0x02) in Parent Information bitmap of the End Device Timeout response.
• 0x266e0700 Beta 2021-05-17
  • Fix internal ZDP queue can get stuck when unsupported requests are received.
• 0x266d0700 Beta 2021-05-13
  • In APS-DATA.indication commands use raw PHY frame LQI value instead with ED value adjusted calculated value
  • Support receiving and sending APS frames to and from endpoints which aren't registered
• 0x266c0700 Beta 2021-05-07
  • Disable unused Zigbee stack code, reduced code size by 3K
• 0x266b0700 Beta 2021-04-29
  • Support custom Node Descriptor manufacturer code when requesting device has Xiaomi T1 MAC address prefix
• 0x26690700 Stable 2021-03-17

• 0x26680700 Stable 2020-12-01
  • Improved end-device management
  • Improved neighbor table handling and routing
  • Reduced code size by disable unused stack functions

  • Improve frame counter handling in NVRAM and after power-up
• 0x26650700 Beta 2020-09-13
  • Improve frame counter handling to never get lower frame counter when previously used
  • Hardening Serial Protocol command parser
  • Raise concentrator discovery time from 20 seconds to 2 minutes (lower many-to-one route request frequency)
• 0x26520700 Stable 2020-02-24
  • Initial RaspBee II firmware version
• 0x264a0700 Stable 2020-05-27
