Sample project not working on Galaxy Watch

BY 21 Aug 2020 Native Application Development

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??
