Alexa gadget example

[Mysteryduck]

Hi all,

I've found an alexa gadget example but I can't seem to get it running on my nRF52840-DK. The example I've found was located under repository:

https://github.com/nordic-auko/fw-nrfconnect-nrf.git

I've installed the following tools on my windows 10 PC already:

1) zephyr, This can run the blinky example on my nRF52840-DK, can build and flash.

2) nanoPB, although the NANOPB_PATH didn't got found in the t manifest? I fixed it by hard coding it for now, need to find the solution yet

3) ALEXA_EMBEDDED_PATH, same issue as nr 2 and also hard coded it temporary just to see if building it is possible

Now West is willing to start building the application as all configurations are met but I still get errors. 

file *\nanopb_generator.py", line 50, in <module>
from .proto import nanopb_pb2
ModuleNotFoundError: No module named '__main__.proto'; '__main__' is not a package

Anybody got an idea on how to proceed?

Thanks

[Simon]

Try running the following:

cd <sourcecode_root>\ncs
pip3 install -r zephyr\scripts\requirements.txt
pip3 install -r nrf\scripts\requirements.txt
pip3 install -r bootloader\mcuboot\scripts\requirements.txt

Best regards,

Simon

Hi Simon,

Thanks for your reply. I did the commands you told me but all of the requirements where already satisfied.

The error message has not changed as well when I retry my command:

>west build -p auto -b nrf52840dk_nrf52840 samples/bluetooth/alexa_gadget

Hi, I've found something

I've uninstalled all protobuf packages (also python3-protobuf) using pip.

Reinstalled only the protobuf 

>pip3 install protobuf

And it got me further now. I only neet to figure out how 2 files are not found.

Got the following error now:

I think can be solved by simply adding the gadgets.h file to nrf/include/bluetooth/services.

Check out this commit, which I think includes all the changes that should get applied to the nrf repository in order to make the Alexa Gadgets service sample to work.

Best regards,
