Hello! I tried building the sample app "Bluetooth LE Service". But there is a problem with this service app.
This app looks good to working. but can't found this device bluetooth scan on phone.
I found the problem in logcat. The reason is It_adapter_le_set_advertising_tx_power_level api.

bool bt_common_set_tx_power_level(bt_advertiser_h adv_h, bt_adapter_le_packet_type_e pkt_type, bool flag)
{
int ret = bt_adapter_le_set_advertising_tx_power_level(adv_h, pkt_type, flag);
if (ret != BT_ERROR_NONE) {
dlog_print(DLOG_ERROR, LOG_TAG, "Function bt_adapter_le_set_advertising_tx_power_level() failed with error: %s.", get_error_message(ret));
return false;
}
return true;
}

The bt_adapter_le_set_advertising_tx_power_level function returned the error code BT_ERROR_OPERATION_FAILED.
The error log is "Function bt_adapter_le_set_advertising_tx_power_level () failed with error: Operation failed".
I tested it under various conditions, but all failed.
1. BT on vs off
2. Bluetooth connection with mobile phone vs without connection
3. Privilege 'tizen.org/privilege/bluetooth'
My devices is Galaxy watch active(SM-R500).
How to fix this operation fail error or how to see more detail log??
