problem with lte_ble_gateway

[Nicked]

I can run some of the samples on my nrf9160 DK, however when it comes to this one I get a assertion error err==11 that I have not yet been able to solve.

ncs/zephyr/subsys/bluetooth/host/hci_core.c:317

err = k_sem_take(&sync_sem, HCI_CMD_TIMEOUT);
__ASSERT(err == 0, "k_sem_take failed with err %d", err);

Hi.

Did you flash the hci_uart sample found in <ncs root>/zephyr/samples/bluetooth/hci_uart (built for nrf52840_pca10090) to the nRF52840 present on the nRF91 DK?

The procedure is explained here, under "Programming the sample": https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/nrf9160/lte_ble_gateway/README.html

Best regards,

Didrik

I had loaded the nrf52 stuff, however the wrong version, the README covered the steps but did not mention specifically the

nrf52840_pca10090 so I of course load the wrong one.

Two other issues so far one is that I need to run the windows version in the administrative mode, else when change from NS to non-NS unit some of the files don't seem to compile correctly.

The second is that I am seeing failures when loading files my system seem to occasionally stop after the compare phase and wait and eventually  return an "unknown error", if I take a completely related hex file and load it into the "disk" space. Rinse and Repeat all works well, my guess is I am hitting a time out on the compare phase.
