Thanks for this.  But can you also show (directions for dummies) how to load this archive into the workspace properly, build the firmware, and transfer the binary to the sensor?

I inadvertently loaded something from the SDK onto mine, and now it doesn't work.

This is awesome (and excellent timing, as I just ordered my WICED SENSE kit and I'm exploring now)!

I am a total newbie with IoT, devices and C++; however, a veteran with Java, Web, and other tech.

I'd like to use use the WICED SENSE as the peripheral device - can I use my PC (over bluetooth) as the central device to gather data?

I'd love to understand if I can transmit the collected sensor data to a service via MQTT..  anyone have any thoughts?   --thanks so much!  -Mike

Hi Mike,

To answer your question, PC as central device( No-assuming you don't have BT-LE on it). If you plug in a BT LE usb dongle then you can get data to your PC, since WICED Sense has BT-LE.

Yes you can create a MQTT service , example using rabbitmq and publish the sensor data to your subscribers.

Hi, JT

I have some question about wiced_sense tag.

Is it possible to trace debug message in using sense tag same as DIP switch 2 of SW4 in BCM920737TAG board?

If that is not true, I think it's very difficult to develop user application using sense tag. If it is possible, could you let me know how to trace debug message?

One more thing, I can see another two buttons not two buttons on the side of sense tag, one button on the top side and one button on the other side. Could you let me know these buttons are what for?

Thanks,

Sung-Mok Lee

Hi vik86!  thanks for the reply!  ..that's super exciting.  I got my eye on a BT LE USB adapter so the WICED Sense can talk to the PC.  I have to get my head around how to interface the collected data with the MQTT service I want to publish to..  (wondering if I can do this with a Java?)  - something like:

[WICED Sense Device] ==bluetooth==> [Central Device (PC)] [Java Program / MQTT Library]==MQTT==>[IoT Service]

(forgive my crude ascii drawing) - my gears are spinning!  -Mike

Hi,

The smart tag is showing up in the under ports (COM & LPT) as

Hi cmxers,

As I know you are using wiced sense tag and SDK 2.1.1, right?

If then, please do as follows,

Step 1. Extract coin-cell battery

Step 2. Connect usb cable to PC and then verify whether installed two com ports correctly in device manager

Step 3. Compile and download

Thanks,

Hi vik, maybe JT & Mike too

So i have a windows laptop, bluetooth built in.  It sees the Sense, but won't connect due to driver error. Which I'm guessing is because there's only iOS compatibility for now.  So how does one interface?  Through my Galaxy phone once the Android app is released, and then through Android SDK or WICED-Smart SDK on my pc?

Any advice would be super helpful.

Thanks,

Mike

Sung-Mok Lee,

The reset by extracting and reseating the coin-cell battery worked.

Thanks for the help.

Sorry for the silly question, but how are you compiling and downloading the new firmware?  I've loaded the firmware SDK into the overall Wiced Smart SDK project, but there's no target or makefile for the firmware.

I could really use some step-by-step instructions.  Thanks.

Anonymous

I got it to compile and download.   In case others are struggling, here is the target name that I specified in the make target.  Note that wiced_sense is the name of the subdirectory that I gave for the SDK.  The path is

Path: ./WICED-Smart-SDK/Apps/wiced_sense

Target name: wiced_sense-BCM920737TAG_Q32 download

Now I'm spamming you all.  Sorry...

The console window said the app is running, but the tag still won't start the app via the wake button (after disconnecting and reinserting the battery)

Perhaps my battery is too weak?  I measured it at just over 2 volts.

I assume there's no way to run the tag with power supplied via USB?

Thanks for the feedback

Yes, you are spamming... just kidding.

I don't know the steps that you have taken or if you made any changes, but you can recover the device to the original code.  We are posting that recovery process this morning - So be patient.

It involves removing the board from the enclosure, a sequence of button presses and typing a Recover Target in the Make Target Window - But again, be patient, as we are working on this now.

Regarding the USB supplied power to the TAG:

There is a "hack" to getting the Tag to run with USB Power:

  1. Remove the USB cable after you have successfully programmed the Tag
  2. Leaving the Battery cover off in this process, press the battery into the battery socket until you see the RED Led turn on.
  3. While holding the battery with your fingers making the battery connection, insert the USB Cable in the Tag
  4. Release your finger from the battery, letting the battery drop out of the socket and you are now running the Tag from the USB Power


Thanks

hey mikeyrivs14,

I think we're in the same boat. 

1) i do have an iPhone and was able to successfully interface to the sample app.. ok, cool!

2) i downloaded the silicon labs drivers and can interface to my PC (for compiling code to the kit).. ok, cool - next!

3) what i really want to do (and i think you do too) is interface the WICED Sense to my laptop (which is bluetooth enabled) and use my laptop as the central device to read the data from the sensors.  Once I got that data, I really really *really* want to ship off the collected data to an MQTT service !!  

..I'd like to do all of #3 with Java if possible; as that's my preferred language (vs. C/C++)

..My laptop does see the bluetooth device and identifies it as "WICED Sense Kit" (which I think is good); and calls is a "bluetooth peripheral" (but also says there are no drivers installed for this device (code 28) ) ..so not sure where to go next...

If anyone has any comments - I'd love the insight.   Thanks, Mike

Thanks JT, yes, the procedure worked!

For others, take some care when you remove the board as the screws are tiny and the pushers from the shell will likely fall out (they are easy to replace, but the slots are asymmetrical so they only go in 1 way)

Also - for others - I depleted my battery in a surprisingly short period of time, so perhaps don't leave it in the tag when it isn't in use

Looking for UUIDs for this sensor... Are they available?

I can't find them referenced in code or in docs.  There's a list of UUIDs available in Windows device manager, but I don't know how to map them to the sensors.

For example, the following is available from TI for their sensor:

Thermometer "f000aa00-0451-4000-b000-000000000000"

Accelerometer "f000aa10-0451-4000-b000-000000000000"

Humidity "f000aa20-0451-4000-b000-000000000000"

Magnetometer "f000aa30-0451-4000-b000-000000000000"

Barometer "f000aa40-0451-4000-b000-000000000000"

Gyroscope "f000aa50-0451-4000-b000-000000000000"

Standard:

Key Service "0000ffe0-0000-1000-8000-00805f9b34fb"

+ standard and hidden in device manager:

Generic Access: 00001800-0000-1000-8000-00805f9b34fb

Generic Attribute: 00001801-0000-1000-8000-00805f9b34fb

Device Information: 0000180A-0000-1000-8000-00805f9b34fb

I have the WICED_Sense project built but cannot download to the tag.

All the videos indicate "We are unable to connect to the content you requested"

Thanks

Sorry you are having problems.

Videos should work - Maybe a browser issue.

If you build the project you should be able to download it to the kit.

If not, you may want to recover and do the Make Target again:

Downloading to the WICED Sense is still not working.

Any hints as to to the duration of the key presses?

I have a Tag 3 board that downloads work fine on with the same setup.

You're able to see the sensor show up as a serial port in device manager?

When I compiled and flashed wiced_sense firmware, red LED of WICED Sense turned on, and 'Wake button' doesn't responding.

In this situation, WICED Sense app of iOS doesn't detect 'WICED Sense Kit' device.

I tried recovery, but I got same result.

What kind of cause can be considered?

Hello brownie,

Try this:

  1. Do a "Forget Device" in your iPhone Bluetooth Settings
  2. Close the WICED Sense iOS App.
  3. Remove the WICED Sense Battery and then replace it.
  4. Open up the WICED Sense iOS App and then try connecting again.

Let me know if that works

Is anyone having any luck accessing this thing from a PC with C#?

I can only get generic Gatt characteristics (DeviceName, etc.), and can't get any sensor data at all.  It would sure be great to get some documentation like the folks over at TI provide (http://processors.wiki.ti.com/images/a/a8/BLE_SensorTag_GATT_Server.pdf)

JT -- any thoughts there?

Try a new battery.  They last WAY shorter than you might think.  These days I keep the batter out and run it via USB when testing.

I compiled and flashed wiced_sense firmware, my IDE console output is exactly like the video so I assume the code produces the factory firmware.  However the device acts differently now.  It will pair/connect with my Moto G phone and Android app shows sensor data but the LED is constantly pulsating.  It can no longer be seen by my IPad.

Hello brownie,

What version of iOS are you running?

JT

Hi JT and brownie,

I think we are have the same problem.

Compiling and flashing the firmware from the sources makes the device unseen by iOS 8.0.2. and results in it appearing and disappearing frequently with Android 4.4.2.

I think the firmware built from sources is not identical to the factory installed.

Is there a compiler option?  I did exactly what is shown in your video.

I will purchase another sense so to have a known good and an experimental.

Hi brownie and jpcallahan,

I think i'm experiencing the same situation as you.

I tried to describe it here ?

Did you manage to get traces from device using Broadcom Debug Viewer ?

@ jpcallahan: unfortunately, you seems to be right about the firmware built from source.

I was expecting to start with this sample and build new applications, but right now, I'm stuck with a non functional device, unable to recover it.
