Purpose:
Need to make a broadcaster with following parameters
macid,uuid,temp,rssi,key_state, datetime
Note: If key is press long for 3 sec it will change bit of key_state to 1 else show 0
Settings:
Read datetime from phone/uart and update rtc
Set time interval of broadcast (default time interval is 1sec)
Set UUID
Set Sleep time will be set (say if time is set 07:00 14:00 then it should transmit between those interval other hours it should sleep)
