BLE Latency between App and Sensor

Hi There,

   

I have a BLE keypad that measures the user's response speed (in milliseconds) from a START command that it receives from the App.

   

Obviously the BLE device is very accurate and we have no problem achieving 1 ms accuracy.

   

However, the START command that comes from the App via the BLE cause an unknown latency which we are trying to address somehow as we aim to build a system that is accurate down to the millisecond.

   

Any help will be greatly appreciated.

   

Thanks,

   

Moe

You can try to measure round-trip times by having the BLE device answering that start commando, and measure the time it takes to do so (maybe doing it multiple times).
