Alexa Gadget development

[abe]

Hi, I'm starting a new custom development, that will use NRF52805 SOC.
The project will be one Alexa Gadget device. I have seen several documentations, but I have some question and I need your help.
1 - What about OTA protocol of Alexa Gadget? Have you any NRF SOC FW example that shows how works?
2 - I see that there are a Gadget FW Sample on NRF Connect SDK. I have already developed some project with NRF52832, NRF52840 using IAR Embedded Workbench starting from SDK on Nordic Infocenter. I see the last relesed is 17.1.0 dated august 2021, but there aren't Alexa Gadget examples. Could we have the example for these SDK's?

Waiting for your help, best regards

Hello Abele Barbieri,

1 - What about OTA protocol of Alexa Gadget? Have you any NRF SOC FW example that shows how works?

No, we do not have any such example for the nRF52805 since it is such a minimal device.
For this functionality you'll have to use a bigger SoC.

To my knowledge there is no on-going effort to create an Alexa Gadget example for the nRF5 SDK. Please see this statement regarding the state of the nRF5 SDK vs. the new nRF Connect SDK. If you intend to develop an Alexa gadget I recommend that you switch to using the nRF Connect SDK, since you otherwise will have to implement this yourself for use with the nRF5 SDK.

Best regards,

But I haven't found any OTA FW samples also for other SOC you said. 
Let me know if there are these samples ...

Thanks

Hello again, Abele

In your project, will you be working with the nRF5 SDK, or the NCS SDK?

Best regards,
Karl

I'd rather work with using nRF5 SDK, but you said that there are no Alexa Gadget FW samples inside it.
Let me know ....

Many thanks
Abele

Hello Abele,

There is indeed no Alexa Gadget FW samples for the nRF5 SDK, so I would advice you to switch to the NCS SDK for this development.
Either way, for the nRF5 SDK you can view the different OTA examples here, while for the NCS case you could take a look at this example.

Best regards,
Karl
