[Bluetooth Accelerometer+Inclinometer] BWT61CL MPU6050 High-Precision 6-axis Gyroscope+Angle(XY 0.05° Accuracy)+Acceleration with Kalman Filter, 100Hz High-Stability 6DOF Data Logger for Arduino

I use this device with my own Android app. It works exactly as described, and meets all my expectations and requirements. I programmed my app to connect to the BWT601CL's Bluetooth interface exactly as described by the Google Android Bluetooth development guide, with the additional information provided by the WitMotion documentation for the detailed data format protocol. Like most programming efforts, this was not totally headache-free but the issues were due to my own Bluetooth inexperience and bugs, not due to WitMotion.The device can also be accessed and tested with the "Mini IMU" app provided by download from WitMotion, which shows angles, angular velocity, and acceleration and also allows for admin and calibration. I did not try to use a hardwired PC interface as all functionality is provided over wireless Bluetooth. The documentation states that admin functions are not available over the PC serial interface. This makes sense to me, since it's a wireless Bluetooth device, and there are other different available devices intended for hardwired applications, and even a USB-bluetooth interface for PCs.Customer service has been very responsive and helpful. The only negative I can report is that the documentation has evidently been translated from Chinese and has a few grammatical issues, but as far as I found, there are no technical errors.

There is no instruction manual, you'll need to rely on Youtube videos for setup. The hardware sometimes doesn't connect to Bluetooth and randomly shuts off so if you're trying to collect data it's INCREDIBLY frustrating. The App is nearly unusable, the data output text files are confusing and poorly labeled. I just can't say enough bad about this item. I wanted a simple accelerometer with a phone app but this is trash.

Had some problems getting it to work. The supplied cable was no good - would not charge the battery. When I replaced cable with my own was able to charge and then connect the device via bluetooth to a PC. Had trouble finding the PC software but when I emailed their support they responded within a day with the correct download info. PC program works well for testing the unit after you figure out which port to use (port 4 in my case). The accuracy and stability of the unit look very good for my application, however I was not able to connect to either an iPhone or iPad (tried several of each) via bluetooth. Will have to hard-wire if I decide to use this device in my product.

Where I can get code for Windows 10?

When combined with the "Remote Level" Android app, I have found the WitMotion BWT61CL Bluetooth MPU6050 Gyro+Accelerometer a very useful & cost-effective way to level our T@B camper. It's unfortunate that it is currently not available - maybe a result of China tarriffs & will be back hopefully? I wish the bluetooth connection was a bit more reliable at greater distances such as from the driver's seat of tow vehicle (which sometimes loses connection), but otherwise very helpful for adjusting tongue jack & left/right leveling. After trial & error, I found that choosing the app orientation setting "Left Edge", with the device oriented with label facing upwards & label bottom forward, this produces the expected results with above app after saving settings with the device mounted on leveled trailer. See photos showing device mounted under a cabinet, where front of trailer is at right/through window. This orientation uses the X-axis for left/right leveling and Y-axis for front/back. I used a simple USB adapter plugged into a 120V AC outlet.Much cheaper than another popular device of this type costing around $130. I have no incentive for giving this review other than being a satisfied cusutomer.

This product can be very confusing to set up as their online template did not work for me. However, their customer service team is AWESOME and genuinely cares about their customers. We were able to eventually get my accelerometer up and running. It is fantastic and has a great sampling rate. Highly recommended!

No instructions included, just a QR code that links to the wi0-tmoition site with an well expired cert (proceed with caution). Accept to go without SSL and it is just a linkto Google drive with cryptic file names. Finally find the correct instructions after 15 minutes the pdf has a QR code to download the app (useless on a pdf). Search forever in play store for the correct app, get it installed and the app will not start. Garbage and I wasted enough time. Going back.

It took awhile to get it working. Serial port connection wires fit loosely was the problem.Does the modula need a battery to run with blue tooth?
