Unable to Write Macro to device

awsllcjeff

Laura,
I finally got the code working to calibrate my sensors, but now I am having issues with storing the calibration data in a macro. I followed the code examples to store the data and it seams to work except that it returns null for the macro ID and when I reconnect to the sensor the calibration data is gone. Here is the code I am using:

    CancellationTokenSource cts = new CancellationTokenSource();
                sensorFusionBosch.start();
                sensorFusionBosch.calibrate(cts.getToken(), state -> {
                    Log.i("MainActivity", state.toString());
                })
                        .onSuccess(task2 -> {
                            sensorFusionBosch.stop();
                            final Macro macro2 = metawear.getModule(Macro.class);
                            macro2.startRecord(true);
                            sensorFusionBosch.writeCalibrationData(task2.getResult());
                            macro2.endRecordAsync().continueWith(new Continuation<Byte, Void>() {
                                @Override
                                public Void then(Task<Byte> task) throws Exception {
                                    Log.i("MainActivity", "Macro ID = " + task.getResult());
                                    return null;
                                }
                            });
                            return null;
                        });

Does anyone have any ideas as to why I cannot write the calibration data to the device and store it in a macro? Why the macro ID always returns null? I am using a MetaMotion R model 5 hardware version .4 with the firmware 1.7.2. The app I am using is an Android app running on Android 12.
implementation 'com.mbientlab:metawear:3.8.2'
implementation 'com.mbientlab.bletoolbox:scanner:0.3.1'
implementation 'no.nordicsemi.android:dfu:2.0.2'

Any help would be greatly appreciated.

Thank you,
Jeffrey Winkler

I am wondering if there is a problem with the 1.7.2 firmware. Since I upgraded to the 1.7.3 firmware the macro does seem to save the data and the code returns a value for the macro id.

Laura

Yes, there was an issue with the memory in 1.7.2 and that's why we immediately released 1.7.3.
The issue only affected MMR/MMRL hardware version 0.4

Once I upgraded to 1.7.3 the macro is being saved. But now I have an issue with the sensor disconnecting at odd times. My app works great when the firmware on the sensor is 1.5.1, but not 1.7.3

Laura

What do you mean by "my app works great"?

awsllcjeff

The app that I created for Android works great when the sensor has a firmware version of 1.5.1, but not when the sensor has firmware version 1.7.3. The sensor disconnects from the phone after a minute or two if it has 1.7.3

Can you put some debug statements in your app and also look into the bluetooth raw packets to help debug?
