Major Changes

SDK

  • Memory optimization: iram can be used as memory, thus saving about 17KB memory for user application.

AT

  • Update AT's version to 1.7.0.0.
  • Limited by the size of the AT bin files, only 1024+1024 flash map is supported by default. Therefore, please choose 16Mbit/32Mbit-C1 flash size when flashing these AT bin files with Espressif's Flash Download Tools.
