Hi Gary Lynch
K70 is a little old, so the new SDK didn't add it.
In fact, a lot of new Kinetis chip already add the IOT code, eg, AWS IOT with MQTT.
K70 doesn't have the detail code, but I think you can refer to the FRDM-k64 board, you can download the K64 SDK code from this link:
https://mcuxpresso.nxp.com/en/builder
The Middleware select all:
especially, AWS IOT, freertos, LWIP.
Then generate the code and download it.
You can find the AWS IOT in the folder:
SDK_2.7.0_FRDM-K64F\boards\frdmk64f\aws_examples
The AWS code already contains the authentication.
The direct MQTT with LWIP can be found in the folder:
SDK_2.7.0_FRDM-K64F\boards\frdmk64f\lwip_examples\lwip_mqtt
Please refer to it at first.
If you still have issues about it, please kindly let me know.
Kerry

Hi Gary Lynch,
I check it on my side, the IAR project exist:
So, if you still have issues, I suggest the toolchain/IDE select all, then download the SDK again.
If you still have issues about it, please kindly let me know.

Thanks again, Kerry.
I downloaded and unzipped it again. When I look in the location you show:
The IAR directory doesn't even exist. What am I missing here?
Hi Gary Lynch,
That's strange, your SDK name is also not correct,it should be SDK_2.7.0_FRDM-K64 do you download it from the link which I recommend you?
https://mcuxpresso.nxp.com/en/select
Please try it again.
If you still have questions about it, please kindly let me know.

Hi Gary Lynch,
That's strange, please give me the same picture like me on your side.

Ok, Kerry,
Here's how I followed your instructions:
1. Follow link to https://mcuxpresso.nxp.com/en/welcome
2. Click on [Select Development Board].
This lands me on a page full of empty text boxes with headings:
- Search by Name
- Select a Board, Kit, or Processor
· Boards
· Kits
· Processors
- Name your SDK
3. I select:
Boards
Kinetis
FRDM-K64F (MK64FN10M0xxx12) {I took this from the graphic in your post of Jun 3, 2020 1:24 AM}
4. The page fills in "Name your SDK" with "SDK_2.7.0_FRDM-K64F"
5. I click on [Build MCUXpresso SDK]
6. This begets a page with "SDK Version" = "2.7.0 2019-12-19."
7. In the "Toolchain / IDE" textbox I leave "All toolchains".
In the "Host OS" textbox I leave "Windows"
8. I click on [Select All]. All the checkboxes to the left get filled with checkmarks.
9. I click on [Download SDK]. After some churning I am asked to accept a software T&C contract, to which I agree.
10. A dialog box pops up with SDK_2.7.0_FRDM-K64F (1).zip, which I open with 7-zip.
11. I unzip the package to K64_SDK2, being careful not to send anything through my wifi connection.
12. I open Windows explorer to the folder you requested:
I don't see much difference, except my files are almost 6 weeks older than yours.
Yes, I am running under Windows 10.
My Embedded Workbench is version 7.80.4.12495.
Hope this gets us closer to the truth.
