When device ble connects to mobile ble how many milliseconds it will take to show the services : Embedded device will send data through ble. I developed android application to receive data, but my problem is 1. When device connects to mobile ble immediately it will send data but I am not able to read data, if I give delay app starts reading characteristics but not collecting data. 2. so When device ble connects to mobile ble how many milliseconds it will take to show the services.  so I can match delay and receive data.
