Can you provide some data samples that illustrate the incorrect timestamps?
-
What are the contents of the "libmetawear-path" file?
-
Connection state handling is explained in the documentation: http://mbientlab.com/androiddocs/2/metawearboard.html#connection-state What other code are you executing in this app? I assume your app is doing more than just scheduling a task. …

Serialize the API state after a successful initialization. Then, if the same board is detected in the script, deserialize the state before initializing the API. https://mbientlab.com/cppdocs/latest/advanced_features.html#serialization

How odd. What is the code inside the commands function? Does the timeout error consistently happen if you are using a clean board i.e. one that was just powered on or rebooted? If rebooted, you need to wait for the d/c event and then reconnect be…

How exactly are you using the board? What is the code you are running?
-
This guide provides a general outline for getting started though it is 3 years old.http://mbientlab.com/docs/MetaWearFirmwareDevelopmentGuide.pdf We do not provide custom firmware support beyond getting started. You are on your own if you decid…

No, once downloaded, the logged data is erased.
-
Originally it was because you were calling "reset". Is your board still losing connection after removing that function call?
-
Everything is consistently working now?
-
Post the CSV data and describe in detail your test methodology. Also include the code you are running.

The connection parameters settings apply when streaming from multiple devices. Since you are already modifying the connection parameters, that point is moot. Can you get 50Hz from each board if you are running your Python code without the opengl …
-
Again, please clarify previous questions 2 and 3. You initially stated you could not connect with the nRF app then you stated you could read the firmware and hardware revision. Post Logcat outputs of the failed connection attempts, specifically…
-
Those higher data rates are only applicable when the sensor operates in "forced" mode, which we do not support.
-
Calling reset reboots the board. It is not meant to be used within a normal app flow, hence being placed in the Debug interface.
-
* The API does not natively support multiple master devices. * See the documentation: * https://mbientlab.com/androiddocs/3/advanced_features.html#serialization * You will have to manually remove the create data routes one by one to remove ever…

I'm confused. Your previous post said it was working before, now you say you weren't using the sensor before. Please clarify. Also, for questions 2 and 3, you said you can't connect with the nRF Connect app yet in question #3, you stated you cou…

Call mbl_mw_debug_reset to reboot the board. It could take 10+ seconds for the bluez stack to detect that connection has been lost but the actual number can vary from platform to platform. What i mean is don't make calls to "set_sample_delay"

You'll need to setup your code to handle high frequency streaming:https://mbientlab.com/cppdocs/latest/advanced_features.html#high-frequency-streaming
-
You can disable advertising when no external connections are desired then restart advertising when you want to allow connections again.
-
No, the unprocessed ppg signal will not be provided.
-
You'll have to manually upload it yourself. Send me the hardware revision and model number of the bugged board.

Sensor fusion data consumes more log memory than the acc, gyro, and mag data per entry thus records less entries. On the other hand, illuminance data uses less memory per entry so you can record more values. Also, the ~500k is total number of entr…
-
You will need to either reset the board or call "mbl_mw_metawearboard_tear_down" if you cannot create the data processor. Ideally this should be done after the script is finished collecting data. You can also remove the "set_sample_delay" calls a…
-
Neither of the images are viewable. Post them on a site like imgur or copy the console output and post it on pastebin.
-
You need to start the accelerometer: mbl_mw_acc_start
-
The firmware does not treat acc and gyro data as one sample and MetaBase starts them in series. They do share the same clock in the hardware thus my suggestion of pairing based on latest start time and earliest end time. The timestamps will never…

* Where on there bike are you mounting the sensor? * How are you configuring the senor fusion algorithm? * Which fused data are you recording? * Please provide some sample data that illustrates this problem

Was the MetaMotionR board working before? If it was, how were you using the board prior to this issue occurring? If not, please contact support directly and follow the steps outlined in the last section of the trouble shooting guide. http://mbie…
