@AlejandroHCruz , I think the most bang for the buck you are going to get is adjusting the connection interval. You can try to set the connection priority via BleDevice.setConnectionPriority(). This only gives you LOW/MEDIUM/HIGH, so there's not much fine-tuning you can do (however, you can set whatever parameters you want in your firmware, given you have access to do that). I think most of the SweetBlue options will have a minor impact compared to adjusting the connection interval. You may want to consider also adjusting the autoUpdateRate to a higher value (increasing the time between update ticks). This will only really make a difference if there are a lot of devices you are working with, but you may want to run some tests to see what difference there really is. As for the slowest poll rate for the defaultStatePollRate, it's really how confident you are in the android callbacks working. The state poll is there because the callback isn't always called, hence the need for polling. I would say somewhere between .5 and 1 second should be good. Again, it's something you will have to test with your device (and several different phones for better coverage).
