Android BLE Library ConnectionPriorityRequest class

[da_carlos]

I am testing the ble_app_blinky example on nRF52840 BLE SoC and the "nRF Blinky" Android application example which uses the Android-BLE library from NordicSemiconductor.

My question is, how should i use the "ConnectionPriorityRequest.java" class from this Android library in order to change the "Connection Interval"

Where should it instantiated? ¿How should it be instantiated?

Thanks in advance.

Hi Carlos, 

As you can see you can have  3 levels of priority when using with requestConnectionPriority() from mBlinkyManager.

At CONNECTION_PRIORITY_HIGH you can have the connection interval around 10-20ms depends on Android version and phone vendors. 

However, to be able to request a specific connection interval it also possible to request the new connection parameter from the nRF52 side. It's handled by ble_conn_params library (initialized by conn_params_init() in main.c). You can call ble_conn_params_change_conn_params() to change the params.
