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

Watts-MacBook-Pro-2:nrf Watt$ west init -m https://github.com/nrfconnect/sdk-nrf --mr v1.3.0
FATAL ERROR: already initialized in /Users/Watt/zephyrproject, aborting.
Note:
    In your environment, ZEPHYR_BASE is set to:

    This forces west to search for a workspace there.
    Try unsetting ZEPHYR_BASE and re-running this command.

[Øyvind]

Looks like there is some confusion ongoing. What is /Users/Watt/zephyrproject/? In your environment, ZEPHYR_BASE is set to: /Users/Watt/zephyrproject/zephyr

Have you tried to initialize NCS inside of a zephyr repo? As the output from your previous comment:

Watts-MacBook-Pro-2:nrf Watt$ pwd
/Users/Watt/zephyrproject/ncs/nrf

NCS is initialized inside of zephyrproject, and this includes another zephyr folder:
/Users/Watt/zephyrproject/ncs/zephyr

Please try to fix this first.

Kind regards,
Øyvind

Morning Øyvind,

This is what I have in my /Users/Watt/zephyrproject directory...

            Watts-MacBook-Pro-2:zephyrproject Watt$ pwd

                       /Users/Watt/zephyrproject

             Watts-MacBook-Pro-2:zephyrproject Watt$ ls

                         bootloader modules ncs tools zephyr

Yes, my Zephyr base is set to.

ZEPHYR_BASE=/Users/Watt/zephyrproject/zephyr

Under ncs, the only directory is nrf. Its empty.

I agree, it looks like my directory structure is messed up. I have tried to reinstall, please see my last posting, but this has failed.

Whats the easiest way to reinstall?

[Øyvind]

Good morning Rod, 

My apologies for the late reply. From your last comment, I agree that something is messed up.

 Try to add a new folder to /Users/Watt/ e.g. NCS. Follow the instructions given here. Inside of /Users/Watt/NCS run the following command in terminal:

west init -m https://github.com/nrfconnect/sdk-nrf --mr v1.3.0

This will clone the manifest repository into NCS. Once complete, run the following commands:

west update

west zephyr-export

Lastly, make sure to install dependencies:

pip3 install -r zephyr/scripts/requirements.txt
pip3 install -r nrf/scripts/requirements.txt
pip3 install -r bootloader/mcuboot/scripts/requirements.txt

Let me know how that works for you.

Kind regards,
Øyvind

Hi Øyvind,

No problem. I followed your instructions above but still seeing problems.

Rod, it looks like it's still fetching information from the zehpyrproject folder (Including boilerplate (Zephyr base): /Users/Watt/zephyrproject/zephyr/cmake/app/boilerplate.cmake)

Have you set zephyr base?

[RodWatt]

Watts-MBP-2:~ Watt$ printenv ZEPHYR_BASE
/Users/Watt/zephyrproject/zephyr

Where should I be pointing?

[Øyvind]

It should be pointing to the Zephyr folder inside of the NCS folder that you initiated. e.g. /Users/Watt/NCS/zephyr

[RodWatt]

I have created 

/Users/Watt/zephyrproject

in here I have

     bootloader 

     modules

      ncs

     tools

     zephyr

I have set up ZEPHYR_BASE as follows

ZEPHYR_BASE=/Users/Watt/zephyrproject/ncs/zephyr

Hi Øyvind,

I deleted everything and started again. I followed this 

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_installing.html#setting-up-the-command-line-build-environment

All very straight forward until I try this.

Watts-MBP-2:ncs Watt$ pwd
/Users/Watt/zephyrproject/ncs
Watts-MBP-2:ncs Watt$ west init -m https://github.com/nrfconnect/sdk-nrf --mr v1.3.0
FATAL ERROR: already initialized in /Users/Watt/zephyrproject, aborting.

What am I doing wrong here?

I know this is difficult to debug remotely, I was hoping  clean install would fix it. If you have instructions for a complete reinstall please let me know, happy to start again 

Rod
