How to use the analyzer with a secured BLE session

When trying to capture for example a session between an application running on an iPad (master) and a Bluetooth device (slave), if the analyzer capture the Attribute Protocol interactions between the two but shows anything higher in the stack than the L2CAP layer , then its a security issue.

In order to solve it, see the keys icons on the top toolbar – being red meaning that the messages are encrypted but the analyzer were not able to decipher them.

Please open the network keys form by clicking on the keys and set the depth to 20, Then reopen the file.

If this doesn’t help – either some of the pairing messages were not received by the analyzer, maybe you used a PIN code and you should enter it or let the analyzer find it.

Recommended 1st step to captured entire session, starting with the devices not paired and then pairing , 2nd step is  going through the GATT tests.

Perytons support can also help by sending them the anlb file and they will check it.

Besdies the Message Sequence View, version 5.1 includes Time Markers for the Time View section

Lots has been said about the new Message Sequence View introduced in the latest version 5.1 of the Perytons Protocol Analyzer that enables a new way to explore messages and transactions with Message Sequence View window:
- Show the transactions between devices and/or protocol layers, with colorful arrows showing message type, direction and timing
- Non relevant layers can be removed from display to allow focusing on the layers relevant for the specific test (e.g. profiles, attributes).

But this is not all,  among some additional improvements like Support for additional PRIME PLC layers and PRIME security in the wire-line narrow band PLC models of this version, there is also the incorporation of time markers into the Time View window.
The time markers enable measuring the time and time-delta of and between relevant events and provide an additional way to focus on time sensible messages and sessions:

Changing the capturing channel through a Script

When performing a single channel process, scripts can be used to set the current capture channel.
This process, for example, can be used to change the capturing channel of the analyzer after receiving a relevant ‘Channel Change’ (in a network using ZigBee channel agility).
The following figure describes a scenario where a single channel analysis is done for channel number 13 and changes to channel 15 after receiving a relevant frequency channel change command (the relevant Script is included in the Perytons Protocol Analyzer wireless user manual):
