Release History

V5.0.0

  • Drop support for Python 2

V4.0.5

Same as 4.0.4. Re-released to fix PyPi upload.

V4.0.4

  • Improvement: Remove Bluetooth specification PDFs, refer to bluetooth.com to avoid copyright issues.
  • Improvement: Add wait_for_response option to subscription methods

V4.0.3

  • Fix: Regression with receiving indications with GATTTOOL backend
  • Fix: Regression with subscribing to characteristics with GATTTOOL (need to use writes, not commands) (#234)
  • Improvement: Don't require sudo for removing bonding (#234)

V4.0.1

  • Improvement: Wait longer for characteristics discovery with BGAPI backend (#201)
  • Fix: Protect against invalid BGAPI packets
  • Fix: Fix parsing fields from BGAPI connection status
  • Fix: Robust to non-UTF8 characters in hcitool scan results
  • Fix: Log correct connection flags from BGAPI response

V4.0.0

  • Feature: Add char_read_long for reading characteristics longer than a single packet (#206, #177)
  • Feature: Add command to change MTU (GATTTool only) (#182)
  • Feature: Allow registering callbacks for device discovery events. (#176)
  • Feature: Support fetching BLE device MAC address (#150)
  • Improvement: Add better serial port error handling for BGAPI. (#162)
  • Improvement: Expand and allow overriding pexpect search buffer for gatttool output to support devices with many characteristics without negatively impacting performance (#209)
  • Improvement: Wait before re-opening BGAPI serial port to improve detection on Windows. (#162)
  • Improvement: Add support for Python 3.7
  • Fix: Use ATT write (not command) by default for char_write
  • Fix: Wait longer for ATT write according to BlueGiga spec
  • Fix: Fix BGAPI device detection (#154)
  • Fix: Stop leaking file descriptors when erasing BLE bonds with GATTTool backend (#188)
  • Fix: Typos (#173)
  • Drop official support for Python 3.4, 3.5 and 3.6.

V3.2.1

  • Improvement: Officially support Python 3.6.
  • Improvement: Permit use of non-standard characteristics in reserved range (#140)

V3.2.0

  • Fix: Reliably auto-reconnect after restarting BGAPI device. Fixes a bug in first attempt at auto-reconnection, only worked in some environments. (#144)
  • Fix: Remove spurious "no handler for logger" warnings (#143)
  • Fix: Use enum-compat instead of enum34, to fix installation in Python 3.4+
  • Feature: Limit search window size for GATTTool backend, to avoid high CPU usage for long running connections. (#123)
  • Feature: Add support for write commands to BGAPIBackend (#115)

V3.1.1

  • Improvement: Convert documentation to RST for better PyPI integration.

V3.1.0

  • Fix: Support platforms without termios (Windows)
  • Feature: Add char_read_handle to GATTTool backend.
  • Improvement: Warn if hcitool requires a sudo authentication.
  • Improvement: Allow BGAPI device more time to reboot for more reliable discovery.
  • Improvement: Interpret "invalid file descriptor" as a disconnect event.
  • Fix: Correctly handle service class UUIDs that aren't 16 bytes.
  • Improvement: Support BLE devices with any UTF8 character.
  • Improvement: Make gatttol prompt timeout configurable.
  • Improvement: Gracefully stop lescan to avoid leaving the adapter in a bad state.
  • Improvement: Allow custom timeout for discovery on GATTTool backend.
  • Fix: Make sure responses to char reads on BGAPI backend are from the requested handle.
  • Improvement: Raise and exception if trying to instantiate the GATTTool backend in Windows.
  • Improvement: If no BGAPI device attached, abort immediately.
  • Fix: Use user's configured HCI device for connection and scanning in GATTTool backend.

V3.0.0

  • [API Change] The BGAPIBackend.connect method now takes the same address_type argument as the GATTTool backend [BGAPI].
  • [API Change] The address_type argument on both backends now requires a value from a new enum, pygatt.BLEAddressType, instead of a string.
  • Made Python 3 support a priority for both GATTTOOL and BGAPI backends.
  • Improve reliability of BGAPI backend by re-setting device for each connection.

V2.1.0

  • Added all standard GATT characteristics. [BGAPI]
  • Move gatttool monitor to a background thread for increased performance. [GATTTOOL]

V2.0.1

  • Feature: Allow unsubscribing from notifications.
  • Improvement: Allow more time to discover characteristics. [GATTTOOL]
  • Improvement: Allow using gatttol backend without root. [GATTTOOL]
  • Improvement: Standardize type of UUID so comparison always works (str vs unicode)
  • Fix: Fix packaging so the version on PyPI can be installed.
  • Fix: Fix Python 3 compatibility.

Thanks to Ilya Sukhanov and Alexey Roslyakov for the changes in this release!

v2.0.0

  • New API with support for multiple BLE adapters.
