Connecting the nRF9160DK to the nRF52833 over Bluetooth

[RodWatt]

Hi,

I would like to set up a couple of boards communicating over Bluetooth; I was hoping someone could provide some pointers.

I would like to connect the nRF9160DK to the nRF52833DK. 

I have programmed the nRF52 on the nRF9160DK with the HCI UART code and the nRF9160 with the LTE_BLE_Gateway code. 

Is this correct?

What should I program the nRF52833 with?

Thanks,

Rod

Hello Rod, 

The LTE_BLE_Gateway sample, or LTE Sensor Gateway sample, is designed to be used with the Thingy:52. It will look for Thingy (name or service UUID) and expect to find Thingy services. Your best chance is to configure the LTE Sensor Gateway sample to connect with e.g. Bluetooth Peripheral LBS

Kind regards,
Øyvind

Hi Øyvind,

Thank you for your reply. So, just to clarify.

1. The LTE_BLE_Gateway code is designed to run with the Thingy52 (or '91 I assume) only

2. If I want want to connect the nRF9160DK to the nRF5233DK I should use the BT Peripheral LBS code. Do I use that on both systems? i.e on both the nRF9160DK and the nRF5233DK

I'm having problems building the LTE_BLE_Gateway code for the nRF9160DK; please could you send me the merged.hex file for this board? I will try and get a Thingy52 to test.

Thanks,
Rod

 Thingy:52 only, as the Thingy:91 is LTE (reference design) similar to the nRF9160DK.

 No, you have to keep the LTE_BLE_Gateway, however, you will need to modify it to connect with your application on the nRF52833DK. This application can be based on e.g. the BT Peripheral LBS sample. This way the 833 will send something to the nRF9160DK, where the nRF52840 Board controller running bluetooth-hci-uart sample will send this via UART to the application LTE Sensor Gateway sample running on the nRF9160.

 Can you please explain what the problem is? What version of NCS are you running?

Kind regards,

Hi Øyvind,

Not sure what version of NCS I'm using. This is what Im seeing..

sorry, forgot to add. I tried updating NCS, but see this
