lte_ble_gateway sample for nRF9160

[Joao Filipe]

Hi everyone

I want to try this sample but first I want to understand how it works, not about the code itself but theoretically how it works. The few things that I know is that, we have to program the bluetooth code onto nRF52 SoC, and program the main code to nRF91 SiP to make this one a gateway to nrfCloud.

Can someone say to me if that is correct and provide me with a little more information?? 

Thanks in advance.

Have a nice day :)

Hi!

Yes, you are correct.

The nRF52840 SoC on the nRF91DK needs to be running the Bluetooth: HCI UART sample from Zephyr. This firmware enables the BLE module of the nRF52840 and transmits the data via UART to the nRF9160 SiP on the development kit. So the nRF52840 communicates with a Thingy:52 and transmits the sensor data to the nRF9160, which acts as the gateway to nRF Cloud.

Hope this cleared it up!

 

Best regards,

Heidi
