unexpected LL_TERMINATE_IND cause thingy:52 to disconnect

[Noon]

Hello,

I'm using Thingy:52 to monitor FSR sensors in addition to MPU data.

I use saadc and can measure up to 8 FSR sensors thanks a multiplexer, it take about 10 ms for sampling the 8 channels (multiplexer is controlled by TWI). 

I'm doing the 8 channels measurements each 20 ms (maximum rate). My connection intervall are min = 7.5ms and max 20ms.

Everything works great, but, sometimes, i have an unexpected disconnect event, cause by the central device (Android). 

I'm not able to understand conditions leading to this situation. Sometimes it works for hours, sometimes the bug appears after 1 second.

There is a sniffer log where the LL_TERMINATE_IND occur

:

Anybody got an idea ?

Thanks,

Hi,

As mentioned, it's the Android device that is terminating the connection.

You would need to look into the logs on the Android device for clues on why the Android device terminated the connection.
