Support / Re: bad Simblee batch?
« on: April 24, 2017, 03:08:22 PM »
Hi Tim,
I am curious if that second line of text on the part is a lot number or a revsision number.

On my 77203 board the part says
RFD77101 Simblee
The  3rd  and 4th line are blank.
Last line is MODEL:R71
(Perhaps these were pre-certified parts.

The parts I got from Arrow say...
RFD77101 Simblee
IC: 6992A-71

So, I wonder if the IC: number is the CE cert number.
What do you have for markings?

Interesting Uses & Applications / SFM Color Sensor - BH1745
« on: April 18, 2017, 05:31:30 PM »
My attempt to interface the BH1745 Color Sensor to Simblee. I originally made the shield to interface to RFduino. But thought it would be more interesting to use it in conjunction with Simblee For Mobile. My intent was to display on the smart device the color detected by the remote Simblee based color sensor.

While the UI part of this project works, I don't quite understand the algorithm needed to get a perfect representation of the color at the extremes like black and white. And that affects the in between results. I am having issues with blues and greens.

My starting sample code is here. It needs work. But here is if you want to hack at it.

It would be better if you provide complete code ready to install. Then one can see what you have going on.

Are you using with Simblee For Mobile?

Do you have a RFduino or Simblee?
You mention RFduino, but you are asking in the Simblee section.

What kind of multicolor LED? The digital neopixel type like WS2812 are complicated. I won't explain this.

Or, the simple 3 separate LEDs in one package type like what comes with the RFD22122 RGB/Button Shield.

For these...
For RFduino there is...
There is an example sketch for this under File->Examples->RFduinoBLE->ColorWheel
And there was a iPhone called the ColorWheel for this.

For the Simblee the same iPhone APP should work. But, I forget if there was an issue with it.

However, for the Simblee the better approach is to use Simblee For Mobile instead, then you can use iPhone or Android.

Simblee Libraries / Re: Simblee library 1.1.1
« on: April 02, 2017, 01:43:22 PM »
Hi Tim,

The 1.1.1 came out when they finally released Simblee For Android support back in June 2016 or so.

What we are waiting on now is 1.1.2 primarily to resolve issues caused Android 7.0.

I don't know why the Simblee site still says Android is in beta coming soon 6.6.2016.
It does seem hard to get corrected documents uploaded to the website.

A couple new ideas that might be helpful?

First, would applying extra flux to the Simblee pads on the PCB before applying solder paste with stencil be helpful?

Hi Tim,

Pre-applying a smear of no-clean flux across the pads works good for me. I use SMD291. Also, I tend to mix a little ot the SMD291 into the solder paste making it thinner and more diluted.

Solder pastes come in different particle sizes. Perhaps a finer particle size is in order.

I do not use any solder on the four square ground pads in the middle of the Simblee.

More verbose is not needed. That library is for AVR microprocessors. Simblee is ARM Cortex M0. Look for ARM based libraries.

Sorry to revive this old topic... Has anyone used more than one QDEC on a Simblee or nRF51822 ?
I have one working but need to add more..

There can be only one.
Unless you use external decoders.

Simblee For Mobile / Re: Simblee with Android 7.0 failing
« on: March 26, 2017, 10:04:48 PM »
After updating my Android phone (Samsung 7 edge) to Android 7.0, I cannot access my Simblee for mobile device anymore. Device  appears at the phone simblee app and appears to connect, but once started it disconnects and exits program immediately after shortly blank screen.
I did not have this problem before update. Phone now gets very hot when simblee device is plugged for a while. I have checked simblee device and it is still running and programmable. I tried re installing Simblee app but with no result.
Anyone experienced the same?

Ouch! That is one of the spooky parts of APPs and cloud based products. Sounds like Android changed something in their API.. again. I don't know why they can't maintain backwards compatibility. Same usually goes for Apple products.

I have sent this upgrade concern to RF Digital and hope they respond ASAP with an update to SFM.

Support / Re: Simblee GZLL performs worse than RFduino GZLL
« on: March 25, 2017, 09:32:33 AM »

 I don't understand what SimbleeCOM is so I am hesitant to go down that rabbit hole.

I am using bone stock RFdigital dev boards, 2 Simblee boards (one is the large one with all pins), 2 RFduino boards and 2 USB serial converter boards.

SimbleeCOM is a RF Digital propriatary modification of  BLE protocol that only works on the Simlbee firmware and not supported on RFduino firmware or other BLE devices. It is not applicable to a mixed Simblee/RFduino/Competitor BLE environment, nor a GZLL project per se.

So whatever is going on with GZLL Simblee vs RFduino needs to be figured out.

Ok, I have learn that the SimbleeCOM.mode has to be in both the send and recv.  Done and works.

I have now change the payload of the sketch to work with buttons assignments and will attempt to light led's

This to mimic the easiest system.

How can I bond or link these together so to lockdown that other stuff can't sniff or interfere.


Hi Wayne,
[HINT] SimbleeCOM has access to a unique ESN for each Simblee chip. So you will need to develop a method how you can best access, share, and  sync up the ESNs for your devices.
It would be cool if you can share your concept of doing so in this thread as I am sure many others want to know too.

Don't know what is happening, other than NO pin should be pulled to 5V. The max is 3.6V. Perhaps you stressed it.

Of course the RFduino and Simblee systems have been great to a point but as you may have implied the closed nature is a huge detraction.  My next choices will be based on how well I can stand alone and be bare metal (not mbed, for example).

If you are comfortable with MBED development you can use the MBED compiler and it's advanced methods to obtain a .HEX file that you can then load onto the Simblee using the JTAG(SWD) interface and blow away the Simblee bootloader in the process.  I don't know if MBED nRF51 support includes the Nordic Gazell protocol library though.

Hi Mark,
All good questions people want to know.

I forwarded your post to the RF Digital team.

I wish we could burn in whatever version we want. Simblee, RFduino, Nordic, our own. etc. at will, and go back.

I think the Simblee hardware is absolutely the best smallest complete solution as far as the Nordics nRF51 is concerned. And boocoo more Simblee modules could be sold if it wasn't closed source... just because it is the best smallest complete nRF51 solution.
Ultimately it would be nice if we had access to 1). source code to fix things faster. 2) ability to reload RFduino/Simblee bootloader/firmware.

I used gattool on Linux.

Somewhere early in this forum there is are RFduino threads of users figuring out stuff. Perhaps check that out. You will have to go back and read through history.
