It is intended for use by applications that require low latency between user action and reconnection/transmission of data. This is only appropriate for small amounts of data EPC Updates the power control feature to remove the open loop power control, and also to clarify ambiguities in power control introduced by the new modulation schemes added for EDR. Enhanced power control removes the ambiguities by specifying the behavior that is expected. Additionally, a go straight to maximum power request has been introduced. This is expected to deal with the headset link loss issue typically observed when a user puts their phone into a pocket on the opposite side to the headset 10 Slide 12 By Grady Green NEXT GENERATION BLUETOOTH V4.0 LE Low Energy Emerging Markets Health Care Fitness and Sports Home Entertainment Security 11 Slide 13 By Grady Green NEXT GENERATION BLUETOOTH V2.1 V3.0 V4.0 Stack 12 https://www.google.com/url?sa=t&rct=j&q=&esrc=s&frm=1&source=web&cd=1&ved=0CCsQFjAA&url=ht tps%3A%2F%2Fwww.bluetooth.org%2Fenus%2FDocuments%2FBW13_DayOne_Session1_BluetoothBasic s.pdf&ei=JEOFUumjHI_PkQfjiIAw&usg=AFQjCNF2JuVjJGHxOXOanVAwbA43RaRlxA Slide 14 By Grady Green NEXT GENERATION BLUETOOTH V4.0 LE 13 https://www.google.com/url?sa=t&rct=j&q=&esrc=s&frm=1&source=web&cd=1&ved=0CCsQFjAA&url=ht tps%3A%2F%2Fwww.bluetooth.org%2Fenus%2FDocuments%2FBW13_DayOne_Session1_BluetoothBasic s.pdf&ei=JEOFUumjHI_PkQfjiIAw&usg=AFQjCNF2JuVjJGHxOXOanVAwbA43RaRlxA Slide 15 By Grady Green NEXT GENERATION BLUETOOTH SUMMARY Basic Bluetooth was covered in class V2.1+EDR V3.0+HS V4.0 LE If you have any questions please email me at ggreen@mail.smu.edu ggreen@mail.smu.edu THANK YOU 14
