Kii Thing SDK for limited resource environments.

• Written in pure C. (c89)
• No dynamic memory allocation.

Kii Thing SDK Embedded use 2 macros.

• KII_PUSH_KEEP_ALIVE_INTERVAL_SECONDS
• KII_JSON_FIXED_TOKEN_NUM

These macros should be defined by applications programmers.

KII_PUSH_KEEP_ALIVE_INTERVAL_SECONDS requires seconds of ping request interval. If the interval is too short, MQTT client often disconnect connection to a MQTT server. We recommend 60 seconds or upper.

If KII_JSON_FIXED_TOKEN_NUM macro is defined, KII JSON library takes resources by myself on stack memory. In KII_JSON_FIXED_TOKEN_NUM case, token size of Kii JSON library is number defined by KII_JSON_FIXED_TOKEN_NUM. If your environment has small stack size, you should use this field and manage this resources by yourself.
