CC33xx THICKMAC Package 0.4.0.1 Release Notes
Table of Contents
Introduction
This CC33xx MCU Software Package delivers components that enable engineers to develop applications for the Texas Instruments CC33xx Wi-Fi devices attached to an MCU.
This software toolkit provides the drivers for CC33xx devices to be used with a Real-Time Operating System (RTOS) on a microcontroller.
This is version 0.4.0.1 of the CC33xx MCU - ThickMAC Software Package.
Disclaimer:
The purpose of this CC33xx MCU software package is to provide a prototype for customers to start evaluating CC33xx. This is not a fully productized release.
*Please note that the versioning scheme was changed and from now contains 4 parts. previous release was R1.3

Dependencies
This release was validated with the following components:
Device Support
CC33xx ICs:
- CC3301
Limitations
- Terminal UART might get stuck due to issue in the - MCU-PLUS-SDK-AM243X_8.5.00.24 driver - workaround available in here
- Current version supports Wi-Fi Throughput of up to 4Mbps - Target for future releases 10Mbps
- BLE Limitations
- For BLE operation, host power authorization should be set to awake
- Wlan_Start must be used before the call to BLE_Enable API
- Once using BLE_Enable, there is no way to turn off the BLE until using Wlan_Stop
- No Co-Existence, need to disable BLE advertise and disconnect BLE connections before using Wlan_Scan and Wlan_Connect
Known Issues
| ID | Summary |
|---|---|
| OSPREY_LDB-1477 | SSID field in scan results is sometimes empty |
| OSPREY_LDB-1069 | Using wlan_sta_role_down without wlan_disconnect in the network terminal example might cause example to get stuck |
| OSPREY_LDB-953 | “-help” attribute for several commands in the network terminal example shows incorrect text |
| OSPREY_LDB-830 | Using more than two “recv” commands in parallel in the network terminal example may return general error code |
| OSPREY_LDB-781 | Static IP/GW/DNS configuration appears in wlan_connect help although not supported |
