下載 SDK

LinkIt SDK 有針對 IoT 晶片的簽約客戶,以及一般使用者,分別釋出不同的軟體包。您可以在此頁面找到這兩種不同的軟體包。

兩個不同的軟體包的使用方法是一樣的,不同之處在於,簽約客戶取得的軟體包具有額外的功能模組,以及在商轉與產品生產過程中所需要的工具組。

簽約客戶

如果貴單位是 IoT 晶片(如MT2523、MT7687 或 MT7697等)的簽約客戶,請從 MediaTek Online 下載您的 LinkIt SDK,以及取得額外的工具軟體與 SDK 功能模組。

一般用戶

如果您不是聯發科技的簽約客戶,而是透過線上或代理商購買了LinkIt 7687 HDK 或 LinkIt 2523 HDK,您可以從以下的連結與列表中,下載 LinkIt SDK。公開版本的 LinkIt SDK 支援 MT7687,MT7697 與 MT2523

 

最新版本:4.5.0

Software features and optimization

  • [MT7686] Added support for MT7686 chipset with the same feature set of MT7682S.
  • [MT2523 + MT5932] Added a reference design to provide Wi-Fi connectivity on LinkIt 2523 HDK with MT5932 HDK. (<sdk_root>/project/mt2523_hdk/apps/wifi5932_ref_design)
  • [MT7682] Added a reference design to support MP3 decoding, AMR decoding and AMR encoding. (<sdk_root>/project/mt7682_hdk/apps/audio_ref_design)
  • [MT7682] Added support for W-Fi AP and STA concurrent mode (Repeater mode).
  • [ MT25x3] Added support for Audio/Video Remote Control Profile (AVRCP) 1.6 of Bluetooth EDR.
  • [ MT25x3] Added support for stereo with two headsets through A2DP and playing from local MP3 file (Advanced Wireless Stereo, AWS).

Bug fixes

  • [ MT25x3] Changing the configuration of connection link in BLE or EDR Piconet might cause receiving data errors.
  • [ MT25x3] While inquiry scan and page scan are enabled and EDR link is established, the EDR link might disconnect.
  • [ MT25x3] When a headset pauses the local music with AWS and a link is connected between the headset and the host, an incoming mobile terminated (MT) call of the host will result in headset crash.
  • [ MT25x3] While debugging with μVision Tools (IAR), suspending the MT25x3 device for over 30 seconds will result in reset by watchdog timer.
  • [MT25x3] If MT call is received from host to the speaker through hands-free profile, the audio source in speaker will not switch to the call, if a Bluetooth speaker is playing MP3 with AWS.
  • [MT7682] Setting Wi-Fi profile with SSID and then setting PSK will result in Wi-Fi connection (in STA mode) failure.
  • [MT7682] In Open-WEP connection, if the connection between MT768x STA and an AP fails, the STA device will not inform the application about the connection failure.
  • [MT7682] If a connection is maintained for over 8 hours between MT768x host in STA mode and an AP with password configuration, the data decryption might be incorrect.
  • [MT7682] In Wi-Fi station mode with special low power state (PS mode is equal to 2), after the connection to an AP is established and DHCP process is complete (AP granted the IP), switching to AP mode will result in system failure.

Notes

  • MT7682S and MT7686 does not support Keil IDE and IAR embedded workbench IDE in this release.
  • [MT2523x, MT2533D] The power consumption of EDR data transmission as master role will be improved in the future release.

Major Changes

  • The SDK is packed in .7z format starting from this version. Install the 7zip tool to unpack it.
  • The name of MT2523 Flash Tool is changed to IoT flash tool. It now supporting MT2523x and MT7682 chipsets.
  • The deprecated Bluetooth middleware under<sdk_root>/middleware/MTK/bluetooth_BA will be removed from this version.
  • Some module paths have breaking changes. Read the release note to know how to migrate SDK v4.3 projects to SDK v4.5.
