Chromium OS has been working closely with Linux Bluetooth community to improve BlueZ stack, and there are increasing needs from applications building their features around Bluetooth. One of the major feedback from these application is the lack of the detailed failure reasons as return for D-Bus method call, and these failure reasons can be used in metrics, optimizing retry mechanism, hinting the reproduce scenario to improve BlueZ stack. The current org.bluez.Error.* are serving the generic errors well. However,g given org.bluez.Error.* errors are used across different interface context which does not serve the detailed failure reasons well. (See https://github.com/bluez/bluez/issues/131) Changes in v3: - Separate and correct error-codes.txt. Changes in v2: - Add documentation for error codes Miao-chen Chou (4): Add error-codes.txt to describe error codes of D-Bus method returns BR/EDR and LE connection failure reasons Include BtdError code in Connect() return Print error code for connect methods client/main.c | 3 +- doc/error-code.txt | 266 +++++++++++++++++++++++++++++++++++++++++++++ src/device.c | 52 ++++++--- src/error.c | 111 +++++++++++++++++++ src/error.h | 52 +++++++++ 5 files changed, 465 insertions(+), 19 deletions(-) create mode 100644 doc/error-code.txt -- 2.32.0.93.g670b81a890-goog
