BLE timers

[amarksjc]

We need to optimize the time it takes for a client running ble 5.0 to securely connect with a remote device also running 5.0.  We'd like to see how long each significant step takes.  Ideas, suggestions... please.

In advance, Thanks.

Hi @amarksjc ,

Hope you are doing well!

There are several ways to optimize the BLE connection time:

• Minimize advertising and connection intervals.
• Optimize scan window/interval balances on the central. 
• Use privacy mode only when required. Disabling it saves time when not needed.
• Disable features not required like 2M PHY, coded PHY, extended advertising, etc.

And for time statistics, you can add timestamps to the code. Also, employing a sniffer to capture packets would be helpful. This link has the installation and usage of NXP protocol analyzer, hopefully it will help you.

Best regards,

Gavin
