MMS Sensor stops transmission
Hi,
I do have the problem that the sensors stop transmission of data randomly. It happens when streaming or downloading Quat data. Interesstingly I cannot reproduce the same behaviour when streaming acc data.
There is no disconnect or reconnect. When restarting the python script there is no transmission of data. I need to do a full_reset to make the sensor stream data again.
Has anyone similar experiences or a solution for that problem?
Additonally, there was an update on the MetaBase - Android app. Since then I cannot find or connect to any sensors since then. (Galaxy S20 - cache and data flush didn't help). Any help in that issue?
yours
Alex

I'm looking for resolution on both of these as well.
hey @atonino and @bwalker, I am looking into these issues. Give me a week to fix and re-release
hey @Laura, I've done some more testing with reduced datarate during transmission. I tested 3 MMS sensors and one old MMR sensor I had lying around. It seems that there is an error in the sensor fusion part. The reduction of sent packages didn't change anything (tested with 100, 25 and 10Hz).
Still same behaviour. MMS sensors are randomly stopping sending data, MMR sensor always made it to the end of the testrun. However, it seems that some MMS sensors are more likely to fail sooner than others.
Hi @atonino,
We have already figured out the issue and will have a firmware update as well as an Android release available shortly. There were two bugs. One was with Bluetooth permissions in the latest Android MetaBase App and the other is with the interrupt handler in the latest MetaSensor firmware. Please stay tuned for updates to test.
Thanks!
A new firmware version will be released today to fix this. Please update your devices.
The Android MetaBase App has also been updated and is already available.
Hi Laura,
Now I am able to connect to the sensors again. However, trying to update the sensor fails with the message:
Is there a quick fix for that?
Thanks!
If you have an iPhone the FW update worked on the iOS app. I got the same error in android as well.
I will check what is going on with Android. You can use iOS to update or try a manual update via Android.
