Re: Different behavior between Evothings Client and native app?

Point of semantics: the Client is a native app. I assume you refer to a Cordova app you built yourself. You'll need to add the BLE plugin before building your app, using either of these lines: cordova plugin add cordova-plugin-ble cordova plugin add https://github.com/evothings/cordova-ble Also wort...

Re: Confused about versions

Apologies. The Readme file was out of date, but has now been corrected. The plugin supports Cordova 5.

You should not be concered, or need to do anything special. Go ahead and use the plugin! :)

Re: Standalone Cordova BLE scanner

"cordova-ble" and "com.evothings.ble" should be the same plugin. It does not depend on any other plugins. Recommended Cordova version is currently 5.4.0. "advertisementData" should be available natively on iOS, if you're using a sufficiently recent version of the plugin...

Re: for loop: connect/do something/disconnect

Delays are not the proper way to approach asynchronous programming. Never use setTimeout().

Instead, you must put your code inside the callbacks from functions like rfduinoble.connect().

Re: for loop: connect/do something/disconnect

app.connect() is asynchronous, such that app.device will not have been set by the time app.measure is called. Also, calling connect() several times in a for loop will cause lots of trouble, since a second/third/... successful connect will overwrite the app.device from the previous connect. You will ...

Re: How can I connect to the client without WiFI?

Yes, if both PC and phone can access the Internet.

Our new version, Evothings 2.0, is designed especially for your situation. Download the new Workbench and the Viewer app. They connect via a cloud-based proxy server.

Re: Charting Components Don't Work

The file 'evothings-app.css' is a hodgepodge of many different stylesheets. It has not been tested with anything but our unmodified example apps. It is entirely possible that our css file caused your graphs to become invisible. I suggest that you keep it removed. If you still need the styles from it...

Re: Charting Components Don't Work

Curious. As you may know, we use use vanilla JS and the Canvas element to draw our own graphs, as seen in the TI SensorTag examples. I have a faint memory of trying and failing to get flotr to work. If you use a static data set and drop the rfduino connection, can you make your app work in a regular...

Re: Send Value from Input Number Box to Write Characteristic

If your number is to be sent as a single byte, I imagine something like this could work:

Code: Select all

new Uint8Array([Number(document.getElementById('ambTemp').value)])
