How do I use Wireshark to see the connection interval negotiated between my nRF51822 peripheral and a central which is a mobile app? Which messages should I be looking for?
I realise it's also possible to check what gets passed to the BLE event handler on BLE_GAP_EVT_CONN_PARAM_UPDATE, but I think using Wireshark will be easier.
Also interested to see what other people have found Android and iOS app centrals to prefer for the connection interval.
If the slave request connection parameter update in a "Connection Parameter Update Request", and this request is accepted by the master, the new connection parameters (including "connection interval") can be found in the "Connection Parameter Update Request", see the attached screenshot.
.
How to implement - Bluetooth L2CAP Protocol - frame or protocol I dont now how it's saide'?!
I only have Frame 1737, Nordic BLE sniffer meta and Bluetooth Low Energy like in your picture.

Many thanks in advance!
