Library Update

• Implement #95 by providing LRTC::epoch().
• Fix #102 by automatically accepts remote connection parameter change request in LBLE library.
• Include peripheral driver (https://github.com/MediaTek-Labs/linkit-7697-peripheral-drivers-for-arduino) in the BSP release package.

Joystick in LRemote

New Features

• Add LRemoteJoyStick control and its example JoyStick.

Bug Fixes

• Improve the button response by queue multiple BLE events.

Tickless Sleep Test 8

Add WiFi::end API and revise init_connsys

 - Separate BLE and Wi-Fi cases when initializing connsys
 - Add WiFi::end API to allow user to manually turn-off wifi

LRemote Update

New Features

• Add LRemoteJoyStick control and its example JoyStick

Bug Fixes

• Fix an issue that causes LRemoteButton to miss button-up events when multiple buttons are pressed together or in a short time.

Bug Fix for BLE and Wi-Fi

Wi-Fi fixes

• #92 WiFi library cannot connect to Wi-Fi AP with WPA + TKIP configuration. Fixed by using mixed authentication mode.

BLE fixes

• #89 Unreliable lookup method used within LBLEEventDispatcher class : use equal_range when searching for elements in STL multimap, instead of using find. find is not guaranteed to return the first element in the equal range.

• #90 Improper characteristic list implementation of LBLEClient class:

  • Add a new set of interfaces to LBLEClient that allows user to identify a characteristic by using service index and characteristic index, instead of using UUID. Note that it is possible for a device to have multiple characteristics with the same UUID.
  • Add a new example EnumerateCharacteristic.ino that uses the new indices-based interface of LBLEClient to list all the services and characteristics in the connected BLE device.
  • Use bt_gattc_read_charc instead of bt_gattc_read_using_charc_uuid to read characteristics.
  • Refactored LBLEValueBuffer to support re-interpreting its raw buffer content into String, float, int, and char types.

• #91: when calling bt_gattc_discover_charc, we need to wait for multiple BT_GATTC_DISCOVER_CHARC event. We added new helper function waitAndProcessEventMultiple that supports such event waiting behavior.

BLE Update

BLE bug fixes

• iBeacon: LBLEAdvertisements::getIBeaconInfo now properly converts byte order and endian of UUID/major/minor data in iBeacon packets. Also, TxPower is updated to use signed integer value type. (#79)
• BLE notification: LBLEPeripheral fixes issues that cause Android apps unable to receive notification sent from LinkIt 7697. (#80)
• BLE write/read: LBLECentral fixes issues that cause failed characteristic read/write when using 128-bit UUIDs. (#82)

Other updates

• Serial now supports additional baudrate 921600, 460800, and 230400, thanks to suggestion from @weixiongmei .

Fix iBeacon Parser

• Convert UUID byte order in iBeacon packets
• Convert Major / Minor endian

LinkIt Remote Update

• Add API updateText to LRemoteLabel
  • Limit the text length to 15 bytes
  • Send BLE notification for updated text label to mobile app
  • Complatible with mobile apps:
    • iOS: LinkIt Remote v1.3.3
    • Android: LinkIt Remote v1.2.20171215-release

Add SoftwareSerial Library

Add SoftwareSerial library that allows users to create a software-based Serial device.

• RX pins: use P2 or P3 as RX pin.
• TX pins: most digital pins can be used as TX pin.

Upgrade to LinkIt SDK v4.6.1

• Update to LinkIt SDK v4.6.1 to fix WPA2 KRACK vulnerability issue.
• Fixes #71: Examples->LWiFi->ScanNetworks won't print specific AP if the BSSID starts with 0x00
• Fixes #69: pins_arduino.h missing in variants/linkit_7697
