How can I use Bluetooth LE on nRF9160DK?

[Pablosanserr]

Hi,

I want to use Bluetooth LE in a project for nRF9160DK. My understanding is that the main program should run on the SiP nRF9160 and it will be the nRF5280 that will perform the Bluetooth communication. However, it is not clear to me how I can use Bluetooth with my nRF9160DK.

Searching through the examples provided by the SDK, I found the lte_ble_gateway example and tried it. I have flashed the hci_lpuart application on the nRF5280 (setting it with the S10 switch) and the lte_ble_gateway application on the nRF9160 (setting it with the S10 switch). I'm ussing the 2.0.0 version of the SDK.

I don't have the Thingy:52 that is required to test the example correctly. I just wanted to test the BLE functionality. However, I was expecting the board to appear in the list of available BLE devices on my phone or computer, but this is not happening.

As you can see in the following image, both applications (lte_ble_gateway and hci_lpuart) build correctly and it seems to work. However, I do not know if the logs displayed through VCOM0 indicate a good functioning of the example.

How can I use BLE in my application with nRF9160DK?

Regards and thanks in advance.

Hi Amanda.

I've checked out this post. I'm using the same example as recommended in the post (LTE Sensor Gateway), as you can see in my first message. However, I can't see the board in the Bluetooth Devices of my phone. Have you got any idea of what might be happening?

On the other hand, the attached example project does not work for me, I imagine this is because it is an older version of ncs.

The lte_ble_gateway example is running as a scanner as the log indicates. 

I have updated the example in that post for NCSv2.0.0 peripheral_lbs_9160_NCS2.0.0.7z. You can flash it to nRF9160 and program the hci_lpuart application on the nRF5280. Then, it should be scanned as Nordic_LBS with the nRFConnect for mobile app.

Hi Amanda.

Thank you very much for your help. The example works perfectly. I will review it in depth and try to make some changes.
