Thanks Luke

1. It makes sense for me, I have asked the devs if they can see any game stoppers that I can't think of

2. Thanks,

Thanks for getting back. Yes there is physical UART from the 52840 to the 9160 so using hci uart for BLE is an option. It seems like it will be easier to just use the 9160 as a serial modem from the 52840 if that's all sidewalk has been tested on and approved for by amazon.

To answer your questions:
1. The purpose is to increase coverage on an exisiting design that only uses the 9160 for communication. The problem is that these devices go in places where cell coverage can be poor. (e.g. closets, basements). I would like to get sidewalk added as the main form of communication and use LTE only as a backup incase of poor sidewalk coverage or if the sidewalk network ever goes down/depricates.

2.Sill in the earlier stages of adding sidewalk into the product. A production ready product is still a ways out.

I'm sorry for the delay.

I think if you were to run Sidewalk on the 5240 you would need to have a physcal UART to the nr9160 (which I presume you would have anyway) since Sidewalk occcipes the BLE. Or you would need to create something running on top of Sidewalk to use UART over BLE

I got some questions form the developers.

1. What's the purpose of the application

2. Is this a proto that is going into production soon?

As of now there are no roadmap to at least port the Sidewalk to the nRF91.

Hi Luke

[quote user=""]Is it possible to use amazon sidewalk on an nrf9160? [/quote]

Unfortunatliy Sidewalk is only supported with the nRF 52840 and with experimental support for nRF 5340.

[quote user=""] have a current solution using only cell from the 9160 but would like to use sidewalk and have the cellular network be a backup in case sidewalk is unavailable. Is this possible or is it only available on the 52840? [/quote]

I will need to check in with the developers for this and get back to you

[quote user=""]Would it be possible to use hci over uart and keep the 9160 as the main processor if a 52840 is required?[/quote]

This should be possible and then I would run something like this on the 9160. However I will check in with the developers if they have any recommendations regarding what would be most efficient in regards to power.
