I have the following problem, I don't know if it is related to the Android-Application or the BT-Module.
The first connection, when the user connectes the Smartpone and the Module, all Characteristics and Data are read within 2-4 seconds (after he entered the pin). But if he reconnects to to the Module, the reading of all Characteristics and Data will take about 10-30 seconds.
Anybody a hint what could be the reason for this?
Solved! Go to Solution.
The controller will send every second new data to the smartphone.
The app based on the sample of android (BluetoothLeGatt)
I don't have other tracing capabilities than the trace of the BT-Module and the log of android.
If I choos "Forget the device", the next connection will be OK. But if I reconnect again, the reading of the characteristics and setting the notifications be slow again.
A few questions:
1. Which BT-Module/Board are you using? TAG3(BCM20736), WICED Sense Kit, USB Dongle?
2. Which version of Android and Android phone are you using?
We have not experienced this scenario.
Thank you. With the shorter intervals, the reading is much faster.
So I have just to check how to change the intervals again in Android.
