Hi,

I've discussed the issue with Carl Richard, and there seems to be some documentation missing. He is trying to fix this.

Combining hci_lpuart and connectivity_bridge isn't straight forward, and at this moment is not supported unfortunately.

Should have tried RTT again after reinstalling v1.9.1, now receiving the log on VS.

Usually there's an Application branch in VS where main.c is, but looks like you have to go to zephyr\samples,
and not even nrf\samples, to get at the source.

Since connectivity_bridge has a main.c in VS, went with that as the base for a merge,
but a challenge right from prj.conf, and main.c was not any better ending in errors.
(probably not ment to be)

Looks like will have to define specific led's at each key step to know what's going on,
if not able to get a standalone going by USB without a DK.

thank-you,

Happy to hear!

[quote user="foxble"]any suggestion as to how to view a log output while testing a connection?[/quote]

The LTE BLE Gateway uses RTT, configured in lte_ble_gateway\boards\thingy91_nrf9160_ns.conf

CONFIG_USE_SEGGER_RTT=y
CONFIG_RTT_CONSOLE=y
CONFIG_UART_CONSOLE=n
CONFIG_LOG_BACKEND_RTT=y

You will need to connect an external debugger e.g. nRF9160 DK (P19) to the Thingy:91 SWD interface (P8) using a 10 pin SWD cable.

[quote user="foxble"]I'm not seeing a main.c for hci_lpuart,[/quote]

In nrf\samples\bluetooth\hci_lpuart\CMakeLists.txt you can see that it uses the main. from

zephyr\samples\bluetooth\hci_uart\src\main.c

# NORDIC SDK APP START
target_sources(app PRIVATE ${ZEPHYR_BASE}/samples/bluetooth/hci_uart/src/main.c)
# NORDIC SDK APP END

And the configurations in the prj.conf found in nrf\samples\bluetooth\hci_lpuart\prj.conf.

More information on the build system can be found under Application Development in the Zephyr documentation.

Kind regards,
Øyvind

great!
had tried merged.hex earlier,
but after reinstalling v1.9.1, thingy 91 now works as a gateway to nrf cloud.

any suggestion as to how to view a log output while testing a connection?

I'm not seeing a main.c for hci_lpuart,
and even if merging connectivity_bridge with hci_lpuart is the right way to go.

thank-you,

Yes you are right, looks like this is implemented in the nRF Connect SDK v1.9.1.

[quote user="foxble"]but no flashing led or a connection to nrf cloud.[/quote]

Make sure that you are programming the \build\zephyr\merged.hex on the nRF9160. I programmed both applications using the nRF Connect for VS Code extension, which programmed merged.hex from both projects.

I was able to get them running on my Thingy:91 sending orientation from the Thingy:52 to nRF Cloud.

there is this commit by Carl Richard Steen Fosse <carl.fosse@nordicsemi.no>,
https://github.com/sigurdnev/sdk-nrf/commit/77329a6c2a1767561eab1e5554bed282e167076e
which has:
thingy91: Adding support for BT over HCI for Thingy:91
This commit adds support in board files and samples for using the
nRF52840 on the Thingy:91 as a BT controller.

Checking v1.9.1, it looks like that commit is there for Thingy 91 on both lte_ble_gateway and hci_lpuart.

I tried again this time using straight zephyr.hex files:
nrfjprog -f nRF52 --eraseall
nrfjprog -f nRF52 --program hci_lpuart-build_2-zephyr.hex --verify --reset --log

nrfjprog -f nRF91 --eraseall
nrfjprog -f nRF91 --program lte_ble_gateway-build_2-zephyr.hex --verify --reset --log

but no flashing led or a connection to nrf cloud.
How was this tested by Carl to know that a connection was happening (BT or LTE)?

Seems like this should work.

thank-you,

Hello,

Per nRF9160: LTE Sensor Gateway documentation in nRF Connect SDK tag 1.9.1 this sample supports nRF9160DK only.

[quote user=""]I came across this post,
https://devzone.nordicsemi.com/f/nordic-q-a/52689/nrf9160-lte-sensor-gateway-on-thingy-91/225659#225659[/quote]

This is fairly outdated. You can have a look at the GitHub repo here https://github.com/sigurdnev/sdk-nrf/tree/main/samples/nrf9160/lte_ble_gateway

No, plans of updates from what I can tell.

Kind regards,
