Issue with Transferring BLE Beacon Data from nRF52840 to nRF9160 over UART on nRF9160dk

Hi,

I'm working on a project with the Nordic nRF9160 Development Kit and am trying to send Bluetooth beacon data from the nRF52840 chip to the nRF9160 chip using UART and then transmot the data further to a mqtt server. 

I have tried using the Nordic nRF9160: LTE Sensor Gateway example (found here: https://docs.nordicsemi.com/bundle/ncs-1.9.1/page/nrf/samples/nrf9160/lte_ble_gateway/README.html#nrf9160-lte-sensor-gateway) to facilitate this communication, but I’ve been unable to successfully transfer the data from the nRF52840 to the nRF9160.

Steps taken so far:

1. Implemented the Bluetooth beacon scanning functionality on the nRF52840.
2. Used the Nordic LP UART and LTE Gateway examples.
3. Tried adjusting the configuration but faced no success.
4. Tried a bunch of other UART examples like UART sample, HCI UART 

Could anyone share insights or examples for transferring Bluetooth beacon data from the nRF52840 to the nRF9160 via UART? Any suggestions on what might be missing or misconfigured would be greatly appreciated.

Thank you.

What version of NCS are you using?  

This guide provides general steps for offloading Bluetooth-related tasks to the nRF52840 SoC, which includes setting up communication between the two chips.

Remember that when programming the nRF52840 on the nRF9160 DK, you need to use the correct board target.
nrf9160dk/nrf9160/ns  and nrf9160Dk/nrf52840
