Out Of Band security depends on the OOB method that is used.

Passkey entry protects against passive attacks IF ECDH is used, and should protect against an active MITM attack (although there are some doubts about that, e.g.

Just works protects against passive attacks IF ECDH is used, and never protects against active attacks.

Numeric Comparison protects against passive and active attacks.

LE Secure Connections and BR/EDR Secure Connections are functionally equal. LE pairing used in 4.0 and 4.1 is since then referred to as LE Legacy.

It also modified the Numeric Comparison association model to be used on Bluetooth LE. Frequency 2.402 - 2.480 GHz Transmit Power +9 dBm (Maximum) Receive Sensitivity -95 dBm 0. One of the main improvements was the adoption of ECDH for pairing. Bluetooth v4.0 specification, supports BR/EDR. See table for a comparison with the Simple Pairing method for BR/EDR (not LE!):

#BLUETOOTH V4.2 EDR UPGRADE#

This was an upgrade to the existing Secure Simple Pairing algorithms for pairing, device authentication, and message integrity. In version 4.1, the Secure Connections feature was added to BR/EDR. Buy Bluetooth V4.0 + EDR Headset Wireless Headphone at cheap price online. Bluetooth v4.0 + EDR вЂEDRвЂ™ stands for вЂEnhanced Data RateвЂ™. In will operate in a factories and the communication is possible without the constraints of distance. Just Works and Passkey Entry do not provide passive eavesdropping protection, because ECDH is not used in LE 4.0. The Class 1 is to have the communication distance of up to 100m, Class 2 is 30m, Class 3 supports the communication distance up to 10m.Version 4.0 ported the exact same security model as BR/EDR to Low Energy ( LE), with the following exceptions: Secure Simple Pairing uses FIPS-approved algorithms for pairing and message integrity and so in essence it upgraded the security of BR/EDR legacy, which is why we call this new one BR/EDR security. The algorithms used in BR/EDR legacy were not FIPS approved. It all started with the initial security algorithms (BR/EDR legacy) for the following security features: Version 4.2 => LE (uses Secure Connections).Version 4.0 and 4.1 => LE legacy (uses Secure Simple Pairing).Version 4.2 => BR/EDR (uses Secure Connections).Version 2.1 => BR/EDR (uses Secure Simple Pairing).For developers, if your chipset supports v4.2, you can take two devices (usually from the same manufacturers) and use the features that it supports. Any vendor without v4.2 will soon start running into trouble. The measurement allowed error is +/- 1-3cm.Most answers to your questions are given in the spec Bluetooth Core, VOL1.PartA.5 Since then, most BLE chipset vendors have announced support for Bluetooth v4.2, even if support is preliminary.
