OpenThread Sleepy demo doesn't work as expected

Hi there,

Built it as follows:

board="brd4317a"
./script/build $board

Flashed sleepy-ftd to one device and sleepy-mtd to another.

On the FTD device, the output was (never saw "sleepy-demo-ftd changed to leader" message as mentioned in the documentation):
sleepy-demo-ftd started

after a few seconds, when I typed "child table" command, I could see one child in the table, but when I went and typed state on the MTD device it was in detached state, I could not ping the FTD.

On the MTD device, the output was:


sleepy-demo-mtd starting in EM1 (idle) mode
Press Button 0 to toggle between EM1 (idle) and EM2 (sleep) modes
[poll period: 2000 ms.]

state
detached
Done

How is it possible that on the FTD, there is a child in the table but state is detached on the MTD device? How to communicate in the case?

BTW, I tried to press BTN1 on the MTD, followed by pressing BTN1 on the FTD, didn't see any UDP messages printed on the CLI.

What did I miss?

gecko_sdk_4.4.0

ot-efr32 (f7cc2e8)

Thanks,

Andy

Hi Andy (@10andy0)!

Unfortunately, I think I may have inadvertently broken radio communication with my [sdk] update to GSDK 4.4.0 PR #723 . Please use fc3d5ea for the time being. I'm diagnosing what went wrong right now.

Best,
Mason

Hi Mason (@lmnotran)!,

Thank you for your reply, I tried what you suggested, but got no console output at all from the devices programmed with the images. I built them as follows:

git clone https://github.com/openthread/ot-efr32.git
cd ot-efr32
git checkout fc3d5eab7d1e3d1be50a35f02ac7d4735dac497a

git submodule update --init --recursive .
# didn't run ./script/bootstrap as already have all dependencies
board="brd4317a"
./script/build $board

Flashed them as follows:

./commander flash --serialno=xxxx ot-efr32/build/brd4317a/examples/sleepy-demo-ftd/bin/sleepy-demo-ftd.s37
./commander flash --serialno=yyyy ot-efr32/build/brd4317a/examples/sleepy-demo-mtd/bin/sleepy-demo-mtd.s37

No output on the consoles of the devices :(

Cheers,
Andy

Hey Andy,

Please make sure that you remove the ARM Toolchain version 12 and re-run script/bootstrap after checking out fc3d5ea to install version 10.3 as support for GCC 12 was not added until GSDK 4.4.0. This should fix things. If it doesn't, please attach the output of the build command.

Best,
Mason

Hi @10andy0 !

Were you able to get the sleepy-demo example working?

Hi @lmnotran,

I gave up on this experiment with the old (fc3d5ea) release. I am using SimplicityStudio right now, it works there. Might look at ot-efr32 later when it is stable.

Thank you

Cheers,
Andrii

I'm glad to hear you were able to get things working with Simplicity Studio! As of #776, ot-efr32 is stable again, so you should be able to try the sleepy demo apps again. If you run into issues again, please feel free to reopen this issue. Thanks!
