I have not tested with zephyr.

Bluez and Zephyr is little complicated and didnt found any examples much.

So tried with pc-ble-driver, there is proper documentation and support. It worked without any efforts.

Anyways i will try once zephyr hex and update you the results

We didnt go further on pc-ble-driver as I already mentioned we are having other priority tasks.

Initially we tried on with zephyr hex file.

Later we moved to pc-ble-driver but didnt go further on that.

Are you able to test the dongle with zephyr hex file..??

If not once try with this hex and let me know your results.

Note: This mac address is hard-coded, you can only use for testing.

From one of your thread

We tried pc-ble-driver on ubuntu18.04 and were successfully tested heart_rate_monitor with smart phone.

Now we want to cross compile pc-ble-driver examples to AM4378 processor based linux system, can you guide us with what changes need to be done while compiling.

Thanks alot for your response

If the BD Address is 00:00:00:00:00:00 then hci cannot detect the bluetooth, this is the public mac addr which is 00:00:00:00:00:00.

Are you able to build the zephyr hex file..??

If you are able to build that add the following in zephyr/samples/bluetooth/hci_usb/src/main.c file and build the hex.

u8_t val[10];
val[0] = 0xFF;
val[1] = 0xFF;
val[2] = 0xFF;
val[3] = 0xFF;
val[4] = 0xFF;
val[5] = 0xFF;

ll_addr_set(0, val);

Now you wont see the above error which you mentioned.
