Bluepad32 v3.0.0-rc0

[3.0.0-rc0] - 2022-01-31

New

• Devices: Support for feature reports.
• DualSense / DualShock 4: add support for get firmware version and calibration values.
  Although calibration is ignored ATM.
• Switch JoyCon clones: Added support for clones (at least some of them).
• DualShock3: Add partial support for DualShock 3 clones, like PANHAI.
• 8BitDo Arcade Stick: Add support for it.
  It keeps responding to inquiries even after the device is connected.
• API to change mappings. Although this feature is not complete yet.
  Missing save/restore, BLE service. Consider it WIP.

Changed

• DualSense: Player LEDs are reported in the same way as PlayStation 5.
• Switch: Don't turn ON Home Light, 8BitDo devices don't support it,
  and might break the gamepad setup sequence.
  Change order of setup commands.
  Change mappings in JoyCons so that it is possible to press "System" button.
• Xbox: Highly improved reliability (based on the new auto delete code)
  Compared to before, it is like 10x more reliable, but the Xbox Wireless Controller
  is still somewhat unreliable.
• API: renamed some functions / typedefs
  • uni_hid_parser() -> uni_hid_parse_input_report()
  • report_parse_raw_fn_t -> report_parse_input_report_fn_t
• These functions are "safe". Can be called from another task and/or CPU.
  The suffix "_safe" were added to their names:
  • uni_bluetooth_del_keys()
  • uni_bluetooth_enable_new_connections()
• Arduino: Seat assignment simplified.
• Bluetooth: request device name for incoming connections.
• Bluetooth: Replaced the old "auto_delete" code, which used "counts", with
  one based on a timer. New code includes incoming connections.
• Bluetooth: SDP query + state machine refactor.
  SDP query timeout using btstack timers instead of ad-hoc one.
  SDP query moved to its ow file.
  Perform VID/PID query before HID-descriptor.
  If HID-descriptor is not needed, don't do the query. Reduces connection latency.
  DualShock 3 and Nintendo Pro Controllers are guessed by their names
  The state machine was rewritten. Although it is still complex, it is much
  easier to understand. In the process, many bugs were fixed.
  Gamepad name is requested to all gamepads. If it fails, a fake one is assigned.
  This is because the "name" is now used to identify certain devices.
  Switch Pro Controller clone improved.
  Re-connection works in many devices, including Switch clones!
  (but not all devices support reconnection yet).
  Overall, cleaner code.
• Bluetooth: Add set_event_filter.
  When doing the inquiry, only devices with a Class Of Device HID are shown.
  This reduces the noise in the console
• Tested with latest ESP-IDF v4.4 (eb3797dc3ffebd9eaf873a01df63aed89fad58b6)

Fixed

• Bluetooth: add log about Feature Report not being supported ATM.
• Bluetooth: Incoming connections are more reliable. Using HCI periodic inquiry mode.
• Bluetooth: fix when parsing device name. Does not reuse previous discovered device.
• DualSense: doesn't not disconnect randomly
• Switch: Don't enable "home light" at setup time.
  8BitDo gamepads don't implement it and might not be able to finish setup.
  Fixed mappings of button "+" in report 0x30.
