What's the NRF Toolbox (Android App) UART's Connection INTERVAL?

What's the NRF Toolbox (Android App) UART's Connection INTERVAL?

At the SDK12's EXAMPLE's Nordic Uart Service's default connection Interval is

MIN_CONN_INTERVAL = 25ms
MAX_CONN_INTERVAL = 75ms

and this Conn Parameter is conducted by Central side (I Guess. Or if it fails, then the peripheral side may construct connection Parameter... ... Actually, I'm not sure about this...)

so, my question is, I'm sure that NRF NUS (Nordic UART Service's Min & MAX) are 25, 75ms, but, What's the NRF Toolbox (Android App) UART's Connection INTERVAL?

I can't find anywhere which connection parameter does the android app constructs with.

  • It's not possible for the Android app to set connection parameters. It's up to the Android OS. But from Android app you can request to change connection priority , see here.

    The easiest to set connection parameters is from the peripheral side like what we have:

    MIN_CONN_INTERVAL = 25ms MAX_CONN_INTERVAL = 75ms

    Of course there is a chance that the central will reject it. But I haven't seen Android /iOS would reject the above parameters.
