`-[PTDBean readAccelerationAxes]` doesn't work well

[sodastsai]

I'm using the iOS SDK to fetch both accelerometer and thermometer values.

The SDK usually returns those sensor values correctly (via the delegate methods). And the console log seems well too.

But sometimes, usually after re-connecting to the bean (connect first and then disconnect repeatedly), the bean doesn't report any update about the accelerometer. It only reports the thermometer's, like following.

The way I used to keep updating the sensor values is like following:

- (void)bean:(PTDBean *)bean didUpdateAccelerationAxes:(PTDAcceleration)acceleration {
    // ... other code ...

    if (bean.state == BeanState_ConnectedAndValidated) {
        [bean readAccelerationAxes];
    }
}

I've found that the line

[peripheral writeValue:data forCharacteristic:serial_pass_characteristic type:CBCharacteristicWriteWithoutResponse];

in GattSerialProfile.m:119 does be called with a nonnull CBPeripheral object each time when I execute [PTDBean readAccelerationAxes].

But I still don't get any response :(

Thank you for the report. I will try to reproduce the issue.

What is status? I am beginning a project and would like to know if the OSX is worth attempting.
