All You Need To Know About Bluetooth Specifications

1.  Throughout the u.  s. and even Europe,
the vary of frequency is a pair of,400 – 2,483.5 MHZ, with 79 1-MHz RF (radio frequency) channels.  The frequency  vary in Japan is a pair of,472 to 2,497 MHz with 23 1-MHz RF channels.

2. a knowledge channel of Bluetooth randomly hops one,600 times per second between the seventy nine RF channels.

3.  every Bluetooth channel is split into timeslots, with all being 625 microseconds long.

4.  A Bluetooth piconet has one master and up to seven slaves.  The master can transmit in even time slots, whereas the slaves can transmit in odd time slots.

5. the information in a very single packet is up to a pair of,745 bits in length.

6.  Currently, there are 2 sorts of information transfer between devices – SCO (synchronous association oriented) and ACL (asynchronous connectionless).

7. in a very Bluetooth piconet, there is up to three SCO links containing sixty four,000 bits per second with all. to assist avoid collision and timing problems, the links of the SCO can use reserved slots discovered by the master.

8.  A master will support up to a few SCO links with either one, two, or maybe 3 slaves.

9.  The slots not reserved for the SCO links will be used for ACL links.

10. one master and slave will have one ACL link.

11.  ACL is either master to at least one slave (point to point) or it broadcasts to all or any of the slaves.

12.  The ACL slaves can solely transmit when it’s been requested by the master.  If the master does not make the request, the ACL slaves will not transmit  anything in the slightest degree.
