Running LTE_BLE_GATEWAY example gives "No HCI driver registered" error

[[email protected]]

Hi!

Running LTE_BLE_GATEWAY example on nRF9160DK rev 1.1.3 gives "No HCI driver registered" error  together with "Bluetooth init failed (err -19)". SDK/Toolset version is 2.8.0

Any help appreciated

Hello, 

Are you able to provide some more details, i.e. did you follow the steps provided in the LTE BLE Gateway sample with installing HCI sample?

Do you get any more logs/information from the devices through serial interface / log output?

Kind regards

Sorry for the delay.

Yes, I followed the sample step by step and I'm still getting 'No HCI driver registered' error

I'm sorry but I will need more details in order to understand where the issue arises. 

How are you building the project, i.e. for what board? 

Kind regards,
Øyvind

I'm building the project according to the steps described in the web page mentioned. The board is nRF9160-DK (PCA10090, 1.1.3). SDK version is 2.8.0. 

Built first a sample from samples/bluetooth/hci_lpuart and flashed the nrf52840 as instructed. Terminal connected to the VCOM1 shows an asteric after flashing

Built then Gateway sample. Using board version number as instructed in the documentation. Builds without problems. After flashing terminal connected to VCOM0 shows, that 

*** Booting nRF Connect SDK v2.8.0-a2386bfc8401 ***
*** Using Zephyr OS v3.7.99-0bc3393fb112 ***

[00:00:00.339,050] <err> lte_ble_gw: Bluetooth init failed (err -19)

I'm happy to provide more details if needed

Hi Allan, I have the exact same problem.

This thread is what I used to get my board to work again:

https://devzone.nordicsemi.com/f/nordic-q-a/119409/lte_ble_gateway-failed-bt_hci_core-no-hci-driver-registered-on-various-sdk

Hope this helps.

Thank you Dawid for pointing it out!

Did I got it right, that using SDK 2.7 for hci_lpuart and SDK 2.8  for lte_gateway does the magic?

Sounds more like workaround for me but if I can continue  with my POC I'm good with that

Yeas also you need to adapt the overlay and config files as mentioned in the ticket.

Yes it does seem like a hack. hopefully it gets fixed soon.

Got it working, thanks!

Hopefully, it will work without the workaround soon.
