NSRangeException in downloadLogAndStopLoggingAsync?

in iOS
I'm having trouble getting logging to start and stop simultaneously on multiple devices I'm connected to. More specifically, I'm getting an exception I've traced down to something happening in my call to downloadLogAndStopLoggingAsync by eliminating lines one by one.

Here's my call to the function where downloadProgressAccel is a UILabel






[[currdevice.accelerometer.dataReadyEvent downloadLogAndStopLoggingAsync:YES

                     progressHandler:^(float number) {

                         // Update progress bar, as this can take upwards of one minute to download a full log

                         [self.downloadProgressAccel setText:[NSString stringWithFormat:@%f,number*100]];

                     }] success:^(NSArray<MBLNumericData *> * _Nonnull result) {}];


And the error trace

2016-04-26 20:37:09.648 Simple MetaWear Test[1957:786861] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 7 beyond bounds [0 .. 6]'

Thanks for the help!

    I tried to get the logs using the sample MetaWearApp and it likewise crashed when it tried to stop and logs and it started downloading. However, the second time around, everything worked fine.

    Edlee,

    We were actually just debugging this issue and already have a fix.  I'll just need get a release published, should happen within 24 hours.
