BLE 5 Overview

Bluetooth 5 it is highly likely they belong to one or more of these three major advancements:

• 2Mbs for higher throughput and/or energy saving
• 500/125kbs modes for considerably increased range (x4)
• Advertising extensions for increased broadcast capacity (x8)

Advertising extensions :
       Allow add more payload on advertising data packet. by use the secondary
  advertisement channel(previous data channel).enables chaining of advertising packets to create
  greater advertising data payloads of up to 255 bytes.

      Periodic advertisements comprises packets sent at a fixed interval to synchronized devices via
  “connectionless” broadcasting.By using periodic advertisements,scanning devices can more
  consistently “follow” the advertiser and monitor its updates more frequently.

      Connectionless broadcasting is further boosted because Bluetooth 5 features an eight times
  higher broadcast capacity compared to previous versions of the technology.
