Hello.  I’m make BLE connection to transfer data between ios and tizen.

IOS advertise their service and characteristic and tizen catch them.

But data send and receive is not work.

As I see, IOS fucntion ‘didSubscribeToCharacteristic’ callback have to be called to send data.  But in tizen, there are no subscribe concept.

Only gatt connect, gatt client create, and read(get), write(set) value functions.

I can make gatt client, but data send and receive is yet.

When I send and receive with ‘bt_gatt_get_value or bt_gatt_client_read_value’ and same with set, wirite, IOS function ‘didReceiveReadRequset and didReceiveWriteRequests’ is called.  But It seem to that is not right function to send and receive data.

What is subscribing BLE service in tizen?  Or there are someone who successed in BLE data transfer between ios and tizen?
