Just opened this webinar for enrollment.

Sounds like a topic made for the community!

Enjoy,

Dates and times are often complicated for people living in Europe, but I'll try and be there! The topic does indeed sound very interesting (and a requirement for IoT development).

Questions and Answers from the Webinar

What functions have the wifi module embedded? Can it run as a wifi access point to configure it directly from a smartphone and as a wifi client to connect to an external server on the internet?

We have several functionalities embedded in the wi-fi module. It can be configured as a STA (station), and AP (access point, with support for 4 stations), or Wi-Fi direct mode.

For provisioning options, we support AP mode, TI proprietary smartconfig, WPS (Wi-FI protected Setup). In AP mode the smartphone can connect to the device as a station, and configure the device with the desired network credential. Once the device switched mode from AP to STA, it will connect to that network.

What is the maximum speed that Wifi can support?

The measured throughput on the device is 16Mbps for UDP, and 13Mbps for TCP connections.

Does it support a ARP static table?

The device while in AP mode will be able to allocated IP address to its station, via the DCHP process. It also supports static IP address, and support ARP static table.

In which languages can it be programed? c? c++? python?.

The default language for the CC33220 examples in the SDK is C.

Generally C++, and Python are not the typical language for MCU based applications. C++, and Python are used for CPU based operating systems programs/scripts.

What is the maximum power at the Wifi module ?

The output power of the wifi device is 18dBm @ 1DSSS, and 14.5dBM at 54OFDM

What kind of RTOS does the CC3220 use?

CC3220 supports FreeRTOS, TI-RTOS, or no-OS

Does it have analog inputs to connect sensors?

The analog input to the device is to the ADC input (4channels 12bits input)

The CC3220 can be connected to sensors with the use of its I2C peripheral as well. We have an accelerometer and a temperature sensor by default on our EVMs.

In addition to these we support other peripherals such as I2S, UART, SPI, SD/MMC, and 8 bit parallel interface camera.

Is it possible to increase RAM size externally?

This is not a common thing to do and would not be recommended to do so.

The CC3220R and CC3220S support an internal 256KB of RAM. For larger application, the CC3220SF combines an internal 256kB of RAM with an integrated 1MB XIP Flash.

9. Does it support FPGA ?

The CC32xx devices could be interfaced to FPGA, using one of the physical interfaces (SPI, Parallel, I2C). We do not provide a reference code for FPGA support.

Does the chip support Apple Homekit?

Yes, CC3220S and CC3220SF variants support Apple HomeKit. The HomeKit SDK plugin is available online from www.ti.com/cc3220sdk. It is installed on top of our based SDK.

Will the module be FCC certified?

Yes, the module will have regulatory certification for worldwide application. We will have certification compliant for FCC, IC, CE (RED), TELEC, and SRRC.

Can the serial flash be used for other user purposes such as backlog and more?

The SFlash has space allocated to the developer’s files and data, for their use as they see fit. The NWP write to the sFlash on behalf of the MCU.

What is the minimum size of the external flash?

The minimum size of the external sFlash is 16Mbit. We recommend the use of 32Mbit, in order to allow for OTA, once the device has been released to production. The sFlash size can be increased up to 128Mbit.

14. What is the minimum size of the external flash?

Is there a module version of the CC3220?

Yes, there are module versions for the CC3220S and CC3220SF devices. The module samples can be requested today online from www.ti.com/cc3220mod

We will release the module without antenna to market at the end of June 2017. We will release the module with on-board antenna in 3Q17.

Is there a LaunchPad planned or available? In that case, is support from Energia planned for the CC3220, as it is already done for the CC3200?

We will have the module Launchpad available 3Q2017.

Energia is supporting the CC32xx devices. The team has been looking into enabling Energia for CC3220 as well. There is a beta version already out for supporting CC3220 - interested parties can contact Energia for this. http://energia.nu/contact-us/

Is the module version pin compatible with the CC3200MOD?

[Beatrice] Yes the CC3220MOD is pin to pin compatible with the CC3200MOD

18. Is the module version pin compatible with the CC3200MOD?

What is the SFLASH size of the CC3220MOD?

[Beatrice] The sFlash inside the CC3220MOD is a 32Mbit sFlash

How many devices can be connected through the wifi?

[Beatrice] While we are in AP mode, we can accept connections from up to 4 Stations

As AP (access point) does it need more RAM or external flash?

[Beatrice] As AP, it doesn’t need more RAM, or external flash. It important to note that the AP mode is fully supported by the NWP. It doesn’t utilize the resources from the application’s MCU such as the 256KB of RAM, this is dedicated to the user’s application.

What kind of RTOS does the CC3220 use?

[Beatrice] CC3220 support FreeRTOS, and TI-RTOS

Can it run on cr battery and for how long?

[Beatrice] Yes, it can run on battery. For instance it can run on 2AA batteries for several years.

The exact battery lifetime will depend on the profile that is implemented by the developers.

What is the actual RAM size that applicaton has?

[Beatrice] The User application has access to the full 256KB of RAM in CC3220S

CC3200 digital pins are working on 3.3v or 5v?

[Beatrice] The Vio is tied to Vbat. Vbat supported options are input voltage from 2.1v to 3.6V or pre-regulated 1.85V. Therefore Vio will be working at 2.1V ~ 3.6V or at 1.85V, depending on the voltage of Vbat.

Are there migration instructions for moving from CC3200 to CC3220 (HW and FW)?

[Beatrice] Yes, we have migration instructions to move from CC3200 to CC3220. It is part of our SDK documentation. Please access the SDK from this link www.ti.com/cc3220sdk

Here is the direct link to the migration guide: http://software-dl.ti.com/ecs/SIMPLELINK_CC3220_SDK/1_30_01_03/exports/docs/simplelink_mcu_sdk/SimpleLink%20Gen1%20to%20Gen2%20SDK%20Migration%20Guide.pdf

Do you have SDK for connection with ASW or Azure?

[Beatrice] We support AWS, and we will support Azure as well. Its development is ongoing.

AWS support for CC3220 can be accessed from this TI-REX: http://dev.ti.com/tirex/#/?link=Software%2FSimpleLink%20SDK%20Plugins%2FSimpleLink%20CC32XX%20SDK%20AWS%20IoT%20Plugin
