Sending data

Question

Hi all, 
 I have a small question. If a GATT server needs to send data to a GATT client(about 65 bytes), does it have to create a service first and then adds characteristic, or it can use directly sd_gap_gatts_hvx function()? 
 Regards,

Hi there, 
 You will need to add a service and a characteristic to send arbitrary data. Once you have the handle to the characteristic you can use sd_ble_gatts_hvx() to send data. Alternatively, if it's easier for you, you can add the service and characteristic on the peer device and use sd_ble_gattc_write() to send data, acting as a GATT client.
