gerardsgs,Are the LEDs the only thing not working? Can you still connect and use the accelerometer for example? Please let us know when you troubleshoot with the MetaWear App.
-
jmacgill,That is a battery failure, please dispose of it appropriately; this is extremely dangerous! A battery that is "fat and squishy" has permanently failed and can catch fire at any time. Please have a sand bath nearby in case of combustion and…

MetaWear has PWM on the haptic driver pin.
-
kandalf12,You should check out the Github Wiki for the Android API, it will have example code snippets.
-
You aren't. You receive values that are relative to a reference/supply/base/system voltage, in the MetaWear case, it is 3 Volts. https://learn.sparkfun.com/tutorials/analog-to-digital-conversion
-
I don't think I understand your question here
-
Chatai, We don't have a PWM function in the MetaWear API but you should check out the Neopixel module and simply attach one Neopixel LED (and you would get all the functionality you need!) http://projects.mbientlab.com/metawear-ios-and-neopixe…

Igor,We are working on it. We were waiting for a nice 1.0 firmware release to put out examples (and it just came out!).
-
It uses a similar protocol.Your best bet is to get another MetaWear board or email us to swap your current board for a new one.
-
gerardsgs,Also try searching for the beacon UUID in reverse byte order. Do you have a general sniffer you could use instead of a beacon App?
-
Jonas,You don't need custom firmware for my first three proposed ideas. We now support bonding (see ANCS app and the latest firmware release) and if you use a backend for auth then it doesn't mean you need to alter the API or firmware on the devic…
-
Igor,Remember that MetaWear is a 3V tolerant board, not a 5V board. Basically it can't take any inputs higher than 3V or measure them through the ADC (the reference voltage is 3V so it doesn't have measurable values for anything higher than that). Y…

Practical transfer rates for Bluetooth low energy technology are below 100 kbps (actual payload of roughly 1/20). White paper for educational purposes: http://www.anybus.com/downloads/Wireless technologies for industrial communication.pdf

No the download link is below the case description (no need to purchase). I just checked.
-
kklobe,We don't actually have any other file formats unfortunately.

misheikh - Streaming via BLE limited to <200hz from accelerometer due to bandwidth saturation - Logging limited to around 10-15 seconds of data at 800hz from the accelerometer My suggestion would be to log the GPIO value at 100ms and d…

Hey kklobe, you can download the STL files from our Shapeways store, there is a link to DOWNLOAD PRODUCT next to the dimensions box.https://www.shapeways.com/shops/mbientlab
-
abbas8000, You should instead use the event module and set up the GPIO pin as a notification (callback) Polling the GPIO pin on a timer is not the best way to do this.
-
We are not sure yet if we can fix with a firmware update or if we will be looking for better ICs for the MetaWear battery charging circuit.
-
Igor,That is an issue that we have been seeing for a long time; it is a hardware issue, not a software one (your code is working) and we are attempting to solve it.
-
Jonas, The problem is everyone always wants a different size screen for their product. Some folks want 2in screens, some want 1.5in screens, some want OLED, some want black and white LCD. You simply can't make a dev board with a screen that accomm…
-
Mike, Did you check the battery levels on your device? Did you try using the Nordic tool to update (see other posts related to this)? Did you try using a different Android device or a different iOS device? Did you try to scan for MetaBoot using…
-
You could do it many ways, here are some random thoughts on top of my head:1. Use Parse/rest (some kind of backend app) and have a login in your App with a password and username 2. Force users to bond their devices with the MetaWear upon first use …
-
We will be releasing other Apps for Android.
-
The MCU/stack we use does not support broadcasting while in a connection.Also that would be a BLE/beacon violation.
-
Have you tried using the Nordic tools as suggested in our other posts?
-
You have to disconnect from the device before it will start beaconing.
-
Did you wait 30 to 60 seconds before reconnecting?
-
Sometimes I think: Android + BluetoothLE = absolute entropy
-
Did you open the .workspace instead of the .xcodeproj?You need to open the entire project, not just the App or pods by themselves.
