I'm working on a project which needs to send messages with the shortest latency possible.
Each message is small enough to be sent in a single transmission, at the moment I'm just sending single bytes.
I'm setting a GPIO pin on one board, sending using esp_ble_gattc_write_char and setting a corresponding pin on a second board.
At the moment I'm getting latencies of ~130ms which seems a little slow.
Has anyone had a similar experience? Anyone have any idea what I could to minimise this latency (other than setting connection parameters)?

Min connection interval is 7.5 ms with step of 0.625ms.

As my original question stated:
I'm looking for factors other than the connection parameters which may affect the latency, as I've already set these parameters to provide minimum latency.Anyone have any idea what I could to minimise this latency (other than setting connection parameters)?
