"No files to send" after download
After logging quaternions and Euler angles in a MetamotionC with the MetaWear app from Android Store, I downloaded data using my Android phone. At the end of the download, when I selected "share data", I received the message "No files to send". Do you know why it appeared ? Normaly I did nothing wrong. Is there a way to find the data back ? They are very important for me. Right after, I tried a new time to download data as I saw a little red circle next to the sensor name. But this time, the download took only 1 sec and I recieved same error message "No files to send". After reseting the sensor, the Metamotion is now working fine.
Also, usally I am working with the windows 10 App with 2 MetaMotionsC (not at the same time). I am using an Android device since a few days because on the Windows app only one sensor appears for logging and streaming. It is always for the same one and also when it is disconected. I tried by reinstalling the app but the problem still occurs.
