I'm trying to change the BLE scanning interval and window for a test with one of our suppliers. I'm able to change these values with hcitool -i hci0 cmd 0x03 0x001C 0x00 0x08 0x12 0x00 where 0x00 0x08 is the window and 0x12 0x00 the interval (the defaults on the pi it seems). However i want to use a larger window, and 0x00 0x10 is not a problem, but setting this higher to 0x20 is not accepted if i read it back. The same when trying to lower the interval under 0x1200 it seems.
Is there a reason that this is not accepted? I'd like to make the window a lot bigger, close to 100% of the interval for the tests, but i cant raise the window high enough or the interval low enough.
Thanks!!
