Wednesday 20th September 2017

LinkIt SDK v4.6.0 is now released.

This is a release with bug fixes.

Software features and optimization

  • [MT25x3] Added support for A2DP source of Bluetooth EDR.
  • [MT25x3] Added support for Bluetooth LE multi-link concurrent operation (1 slave and 4 master Bluetooth LE links).
  • [MT7682, MT7686] Added support for Wi-Fi WPS.

Bug fixes

  • [inear_noodles_headset_ref_design] Cannot power on the device after it’s powered off by unplugging the USB charger.
  • [inear_noodles_headset_ref_design] Local music sometimes stops playing after switching to the next song.
  • [inear_noodles_headset_ref_design] Local music volume is too high.
  • [cord_free_headset_ref_design] Local music stops playing on a slave headset after disconnecting from Bluetooth on a smartphone.
  • [bioband_ref_design] HRV cannot function properly, after executing the blood pressure unit.
  • [MT7682, MT7686] Wi-Fi throughput is less than expected in A-MPDU. There are two frame aggregation mechanisms for 802.11n (A-MSDU and A-MPDU) that are used to reduce the package header size and improve the overall throughput. The type of frame aggregation is determined between Wi-Fi AP and Wi-Fi station. A memory leak issue is fixed when in A-MPDU resulting low throughput.
