Hi Susheel,

memcpy(&discover_uuid[0], BT_UUID_BAS, sizeof(discover_uuid[0]));
		discover_params[0].uuid = &discover_uuid[1].uuid;
		discover_params[0].func = discover_func;
		discover_params[0].start_handle = BT_ATT_FIRST_ATTRIBUTE_HANDLE;
		discover_params[0].end_handle = BT_ATT_LAST_ATTRIBUTE_HANDLE;
		discover_params[0].type = BT_GATT_DISCOVER_PRIMARY;

Actually there is one typo in code.Need to update the uuid index.

memcpy(&discover_uuid[0], BT_UUID_BAS, sizeof(discover_uuid[0]));
		discover_params[0].uuid = &discover_uuid[0].uuid;
		discover_params[0].func = discover_func;
		discover_params[0].start_handle = BT_ATT_FIRST_ATTRIBUTE_HANDLE;
		discover_params[0].end_handle = BT_ATT_LAST_ATTRIBUTE_HANDLE;
		discover_params[0].type = BT_GATT_DISCOVER_PRIMARY;

And now I am able to get notification from both heart rate and battery monitoring service.

Thank you.

I am able to get both when I enable BAS_CLIENT in your prj.conf.

CONFIG_BT_BAS_CLIENT=y

I am able to see both on my terminal.

Hi Dhruv,

Sorry for delays, I do not see anything obviously wrong in your code. so I will try to test it out myself tomorrow at my desk. Will let you know when I have some observations with that test.
