LR1110 and nRF52840

[Brycemart]

Hello, I am fairly new to nRF chips and microprocessors in general, so I really appreciate the help. I am looking to utilize an nRF5840 and an LR1110 in order go get location via GNSS and report it through Amazon Sidewalk. How can I get these chips to talk? Also, When trying to flash the Template_subghz, I am getting the following output after flash.

*** Booting Zephyr OS build v3.2.99-ncs2 ***
----------------------------------------------------------------
sidewalk v1.14.3-13-g6815ffc
nrf v2.3.0

[00:00:00.487,426] <err> application: Unknown error during sidewalk initialization!
[00:00:00.487,487] <inf> application_state: error = true

I appreciate any help you can provide.

Hi, 

Is there anything in the log before the unknown error? 

Can you navigate to ncs/v2.3.0 and run the command "west update"

Delete any build folder from the template sample, rebuild and flash the device. 

I see that your version of Sidewalk is older then mine and my build does not give any unknown errors. 

As for the LR1110 I need to investigate the support for the device as I only know that the nrf52840 is qualified with the Semtech SX1262.

Hi,

Hi, 

Its unfortunly only the Semtech Sx1262 that is supported by us, the changes from last is that we now have support for the 5340 and Sidewalk there is planned qualifciation for NCS 2.4 with Amazon as seen here
