ASSERTION FAIL [err == 0] @ WEST_TOPDIR/zephyr/subsys/bluetooth/host/hci_core.c:329

[Markus Schlenker]

Hello!

Im using the nrf sdk "lte_ble_gateway" sample on a nrf9160dk_nrf52840 DK. If im trying to run the fw on the board its reseted because of this "fatal error"... The "ble_init" runs without any error, after a few seconds the board is resetted.

I found another I found the tip to delete "CONFIG_BT_DEBUG_LOG=y" and "CONFIG_BT_SETTINGS=y" in the prj.conf. But in my code the 2 config lines are not existing... 

 ASSERTION FAIL [err == 0] @ WEST_TOPDIR/zephyr/subsys/bluetooth/host/hci_core.c:307 k_sem_take failed with err -11 

Has anyone an idea about this behavior?

Hi,

LTE Sensor Gateway sample specifies that board controller (nrf52840) should be first programmed with HCI Low Power UART sample before programming the main controller (nRF9160) with LTE Sensor Gateway sample. The lte_ble_gateway sample should be built with build target nrf9160dk_nrf9160_ns. 

Best regards,
Dejan

The hci is flashed to the nrf52840 correctly, also the gateway-sample to the nrf9160. Any modifications to the config needed to get it run?

Hi,

I have replicated the issue and made an internal inquiry about this. I'll get back to you when I get new information, probably during next week.

Best regards,
Dejan

Thx, im really excited what's going wrong :-)

Hi,

I have tested again using nRF9160-DK v1.1.0, and unmodified samples hci_lpuart and lte_ble_gateway. There were no errors this time. Please use the following command to build HCI Low Power UART:

west build --board [email protected]

and the command shown below for building nRF9160: LTE Sensor Gateway sample.

west build --board [email protected]

Best regards,
Dejan

Hi~

I used STM32f767 as the BLE host to compile the central demo, and the execution program encountered a similar error.

cmd：west build -b nucleo_f767zi samples/bluetooth/central

How to solve this problem in the latest version?

This problem is urgent. I look forward to your reply.

Hi OldSix ,

Since we try to avoid having the same question in multiple tickets for better visibility and clarity, please continue in new case that you have created here.

Best regards,
Dejan
