此頁面提供 LinkIt 7697 Board Support Package (BSP) 各版本的更新資訊。

LinkIt 7697 Arduino BSP v0.10.18 - 2018.04.17

• New Features

  • LRemote library has a new class LRemoteJoyStick that allows you to create a joystick control in the LinkIt Remote app.

• Bug Fixes

  • Improved control event handling in LRemote library

LinkIt 7697 Arduino BSP v0.10.15 - 2018.02.26

• 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 waitAndProcessEventMultiplethat supports such event waiting behavior.

LinkIt 7697 Arduino BSP v0.10.13 - 2018.01.10

• 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 .

LinkIt 7697 Arduino BSP v0.10.9 - 2017.12.20

    • RX pins: use P2 or P3 as RX pin.

    • TX pins: most digital pins can be used as TX pin.

LinkIt 7697 Arduino BSP v0.10.6 - 2017.11.28

• Bug Fixes

LinkIt 7697 Arduino BSP v0.10.5 - 2017.10.20

• New Features

  • New softAP() APIs for LWiFi library. This allows users to turn LinkIt 7697 into an Wi-Fi access point.

  • New library LHTTPUpdate for FOTA (Firmware Over The Air update). See the developer's guide for usage instructions.

LinkIt 7697 Arduino BSP v0.9.9 - 2017.10.03

• New Features

  • New LRTC library provide access to real-time clock module. Please refer to the programming guide.

• Bug Fixes

  • Remove progress report when uploading sketch binaries. The progress report does not automatically scroll and confuses user.

  • Fix #65 : analogWrite() fails after calling pinMode()

  • Fix LRemote event dropping issue

LinkIt 7697 Arduino BSP v0.9.2 - 2017.08.21

• New Features

  • New LBLEPeripheral::notifyAll method that sends GATT notification of the given attribute to all the connected GATT clients. Refer to Example > LBLE >notification for usage examples.

  • Add new method LBLEPeripheral::disconnectAll() that disconnects all the GATT clients.

  • LBLEPeripheral::advertise() now returns error code -1 when adv data gets too long

  • The flash upload tool now automatically detects the on-board Wi-Fi firmware version, and update the Wi-Fi firmware when necessary.

• Bug Fixes

  • Fix an issue that causes instances created by LBLEPeripheral cannot be detected by iOS devices on LinkIt 7697 board with certain MAC address.

• New Examples

  • Added usage examples for built-in libraries LTimer, LFlash, and LWatchDog.

LinkIt 7697 Arduino BSP v0.8.4 - 2017.08.04

• Breaking Changes

• • Migrate from LinkIt SDK v4.2 to v4.3.

  • You need to update bootloader and Wi-Fi/BLE firmware by choosing Burn Bootloader from Arduino IDE tool menu. Detailed instruction here.

  • LBLECentral::scan now clears the scanned device list when re-starting a scan procedure. This is because most BLE devices change their BLE address overtime, so there is no use storing all the previously scanned results. If the user must keep the scan history, they need to backup the scan results before calling scan() again.

• New Features

  • Support MCS GamePad Controller Channel. Check Examples > MCS > Gamepad for example. Thanks to @michaelchien1972 for contributing to this.

  • Users can now update (or restore) on-board bootloader and Wi-Fi/BLE connectivity firmware by selecting Burn Bootloader from IDE menu.

• Bug Fixes

  • Add missing implementation LBLEClient::disconnect.

  • Fix an issue that may cause the board stop responding after multiple BLE scan -> connect loop.

  • Fix #27: WiFiUdp::available() returns incorrect result after parsePacket()

  • Fix #30: Servo::attach(pin, min, max) does not work

  • Fix #36: Arduino SDK build issue under mingw (windows x86/x64) environment. (Thanks to contribution from @michaelchien1972)

LinkIt 7697 Arduino BSP v0.7.11 - 2017.06.01

• New Feature: as requested in #21, Provide new method setServerValue(value) for all controller data channels. Developers may use this method to update the MCS/MCSLite server-side values. Once the value is successfully set, the channel becomes both valid() and updated().

• MCSGPSController now have a new method value() which returns an MCSGPSValue object that is a struct of latitude, longitude and altitude. The exisiting methods such as latitude() are left unchanged.

• MCSPWMController::value() has changed:

  • It now returns a MCSPWMValue object instead of the duty cycle field.

  • A new method dutyCycle() is added to retrieve the field seperately.

• All controller channels are now inherited from a MCSControllerBase<T> template class that provides a common implementat for value(), setServerValue() and _update() logics. This reduces some redundant code implementations. Note that display channels are left unchanged.

• Fix #17: Default USER LED is on

• Fix #18: There are compile warnings while compile the core lib

• Fix #20: Arduino IDE 1.8.2 : "Aggressively Cache Compiled Code" will cause compile error.

• Fix #22: Upload fails when the board support package installation path contains space character

• Fix #23: Request to add clockCyclesPerMicrosecond to BSP

LinkIt 7697 Arduino BSP v0.7.10 - 2017.05.23

• New Feature: TLS/SSL support. LWiFi library adds class TLSClient that supports TLS/SSL connections.

• Simplified implementation of WiFi socket classes, including WiFiClient, WiFiServer, and WiFiUdp. This also fixes an issue that caused MCS library to stop uploading data after 2 minutes.

• Bug fixes:

  • #15: [MCS] MCSDisplayFloat does not have syntax highlight in Arduino IDE bug.

  • #13: [MCS] socket.connect() failed after uploading data points for several times.

  • #10: [MCS] MCSDisplayFloat does not update channel data.

  • #12: [WiFi] ssid parameter of WiFi.begin() is not const.

LinkIt 7697 Arduino BSP v0.7.4 - 2017.05.05

• MCS now supports MCSLite. which is currently in preview stage. Visit the preview introduction page(sorry, Chinese only) for binary download and documentation. To connect to MCSLite instead of MCS, use the MCSLiteDevice class.

• LBLE library now adds two new methods:

  • LBLEAdvertisementData::configAsEddystoneURL() allows users to configure advertisements in Eddystone-URL format.

  • LBLEPeripheralClass::advertiseAsBeacon allows users to create a peripheral that is purely advertised as a device that cannot be connected - most beacons belongs to this category.

LinkIt 7697 Arduino BSP v0.7.3 - 2017.04.19

• LBLE library improvement:

  • LBLECentral is now a singleton. Use `LBLECentral.scan()` instead of `LBLECEntral scanner; scanner.scan();`

  • Add LBLEClient class for connecting to BLE peripheral devices. This class supports service enumeration and read/write to characteristics.

• New MCS library: a library that helps you connecting to MediaTek Cloud Sandbox through Wi-Fi network, accessing device channels.

• Improved speed for sketch uploading.
