I kind of use this as blog to manage the notes about my understanding of the CHIP/Matter project

Every device/controller would hold a peer's session if they are connected. However, there are many different types of messages would be sent between controller/device, so we need a specified channel to handle each type of message. In addition, these ECs have been running in a session, so they could use all the resource of the session. That is, EC is not like session which has extreme complicated establishment process. A lot of time, CHIP stack would create a new EC just for one message. Thus, EC is also kind of a temporary channel.

However, we will have a better understanding of this project if we take a look from structure point of view. So, I would like to put down some note about these two classes: Seesion and ExchangeContext(next post).

May 14, 20222022/04/23 CHIP git hash code 67b4746ad8 I would like to follow the calling stack to understand how CHIP stack receives message. Bascially, it's like a reverse calling stack of "Send Message." Just give you a heads-up, there is an engine to handle CHIP-over-Bluetooth Low Energy (CHIPoBLE) message and I skipped this module because I think it would be easier to understand this kind of code if we got the specification first.
