NRF9160 with NRF52840

[chapman]

Hi, 

On NRF9160DK, there is a nrf52840 chip. 

I want to use nrf52840 as a host controller  with NRF9160, but I cannot find any example to control nrf9160 by nrf52840.

and  we just want to use nrf52840 to control nrf9160  with mqtt. 

Is there any example about how to control nrf9160 by nrf52840?

I can run the simple mqtt example on nrf9160dk, but I don't have any idea how to use nrf52840dk to control it. AT-client mode cannot control mqtt. Do you have any suggestion? Thank you.  

Regards, 

Chapman

Hi.

Can you elaborate a bit on what it is you want to do, and why?

The nRF91 has its own application processor, so it is not necessary to run the application on a separate processor.

If you want to use both Bluetooth and CIoT, it is easier to run the application on the nRF91, and use the nRF52 as a network processor. Take a look at the lte_ble_gateway

https://github.com/NordicPlayground/fw-nrfconnect-nrf/tree/master/samples/nrf9160/lte_ble_gateway

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/nrf9160/lte_ble_gateway/README.html

and hci_uart samples.

We are currently working on adding the possibility of using the nRF91 as a network processor. You can find the relevant pull request here: https://github.com/NordicPlayground/fw-nrfconnect-nrf/pull/1099

And a set of samples for the nRF52 to control the nRF91 here: https://github.com/NordicPlayground/nrf5_clients_for_nrf91_network_service

Note that these samples are not official, and we do not guarantee that they work.

Best regards,

Didrik
