Problem

  • BTP fragment size is limited to 128 (244 in the spec)
  • There is no support for BTP v4
  • The maximum BTP fragment size for Peripheral TX is always limited to 20B without using ATT_MTU
  • Handshake frame has invalid first byte 0x6e (0x65 in the spec)

Change overview

Fixed all the above issues and increase the default BTP Windows size to speed up the commissioning process. Depending on the connection interval it takes now between 1.8 and 3.5 seconds in my tests.

Testing

Tested manually with Python CHIP controller and Android CHIP Tool against nRF Connect platform.

I think in the spec it's defined per-bit so you can use c++14 binary literal 0b1100101.

It's not safe to access line editing state from the IO thread while
inside readline() on the main thread.

Remove the code that attempts to redraw readline after printing logs.
This avoids segfaults during logging at the cost of those logs
overwriting the prompt (this is not trivial to fix as readline
is a blocking API).
