The SimpleLink Wi-Fi CC3230 device incorporates a scripting ability that enables offloading of simple tasks from the host processor. Using simple and conditional scripts, repetitive tasks can be handled internally, which allows the host processor to remain in a low-power state. In some cases where the scripter is being used to send packets, it reduces code footprint and memory consumption. The if-this-then-that style conditioning can include anything from GPIO toggling to transmitting packets.

The conditional scripting abilities can be divided into conditions and actions. The conditions define when to trigger actions. Only one action can be defined per condition, but multiple instances of the same condition may be used, so in effect multiple actions can be defined for a single condition. In total, 16 condition and action pairs can be defined. The conditions can be simple, or complex using sub-conditions (using a combinatorial AND condition between them). The actions are divided into two types, those that can occur during runtime and those that can occur only during the initialization phase.

The following actions can only be performed when triggered by the pre-initialization condition:

Set roles AP, station, P2P, and Tag modes
Delete all stored profiles
Set connection policy
Hardware GPIO indication allows an I/O to be driven directly from the WLAN core hardware to indicate internal signaling

The following actions may be activated during runtime:

Send transceiver packet
Send UDP packet
Send TCP packet
Increment counter increments one of the user counters by 1
Set counter allows setting a specific value to a counter
Timer control
Set GPIO allows GPIO output from the device using the internal networking core
Enter Hibernate state

Note:

Consider the following limitations:

Timing cannot be ensured when using the network scripter because some variable latency will apply depending on the utilization of the networking core.
The scripter is limited to 16 pairs of conditions and reactions.
Both timers and counters are limited to 8 instances each. Timers are limited to a resolution of 1 second. Counters are 32 bits wide.
Packet length is limited to the size of one packet and the number of possible packet tokens is limited to 8.
