Android BLE Transmission and Transmission Interval

In Android 5.0 and later, the BLE transmission interval is

with values such as SCAN_MODE_LOW_LATENCY and ADVERTISE_MODE_LOW_LATENCY I think it's normal to set it up, but
Is there a way to set this to any interval using a timer?

Similarly, the transmitted output does not use ADVERTISE_TX_POWER_HIGH, etc.
I would also like to know how to set the numbers directly.

I can't.Link layer values, such as connection interval, are set in the BLE chip firmware (FW).The FW code is provided binary, not open source.After rebuilding from AOSP, you cannot change it.

SCAN_MODE_LOW_LATENCY is the mode in which the central scans before connecting without pause.It doesn't matter after connecting.
