Support / Re: bad Simblee batch?
« Last post by tolson on Today at 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
1531CAAA
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
1547DAAA
IC: 6992A-71
FCC ID: UY171

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

We'll be receiving more Simblees from DigiKey tomorrow and will be assembling. Results will be revealing. I also noticed different colour, but that could be because of rework. These are chips that were removed from boards after failure.

We recently ordered from Mouser because they were $3 cheaper. It could be coincidental that we started having assembly issues with this batch. Will post more here as we learn.

Thanks!

Mouser slipping?

Sorry you are having issues.  We normally deal with Digikey and they use double protection.
I see that the 2 Simblees are different in color. 

I'm still in development so not ready for prototype as of yet, but a few more weeks down the line I will be.

Simblee For Mobile / Re: Simblee with Android 7.0 failing
« Last post by lsnyman on April 23, 2017, 06:28:28 PM »
When is the new release coming????
I now have customer devices rendered useless because after the Android Update, the Simblee app doesn't work anymore.
It has been almost 1 month since you said the update is in Beta.
Please advise....

Support / bad Simblee batch?
« Last post by Tim on April 23, 2017, 01:14:33 PM »
Hi ..

Trying to explain why we're getting a high failure rate on assembling our boards. We recently ordered from Mouser and received 30 Simblees packaged as in photo, which means someone handled them to take from factory packaging and place on foam. Also found a label on the anti-static bag containing the Mouser order that have never seen before (see attached photo). Wondering about possible ESD events during handling and shipping that damaged chips. Previously all Simblees came from DigiKey and in original factory packaging and we had a much higher success rate. Wondering if anyone has had issues with Simblees arriving defected from different suppliers.

Appreciate any thoughts, experience.

Tim

Simblee Libraries / Simblee_systemOff();
« Last post by Wayne on April 19, 2017, 02:52:53 PM »
Ok, I'm playing around to see how fast Simblee_systemOff(); responds to a pinwake action, and can this be used in SimbleeCOM or is it just for SimbleeBLE?

Doing my elephant count, it is more than 1, but less than 2 .. 
I'm trying to get below ULP mode.. That draws around 1 ma, the systemOff is around 10ua

Interesting Uses & Applications / SFM Color Sensor - BH1745
« Last post by tolson 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.

Simblee Libraries / Re: SimbleeRNG
« Last post by tolson on April 18, 2017, 03:48:27 PM »
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?

Simblee Libraries / SimbleeRNG
« Last post by jaltet on April 18, 2017, 12:12:46 PM »

Hello everybody!

I am trying to have the Simblee generate a random number using SImbleeRNG. here is my code:
Code: [Select]
void Generate_Ticket_Number()
{
 uint8_t stream[8];
 uint8_t N_Ticket[12];
 SimbleeRNG::generate(stream, sizeof(stream));
 
for (int i=0; i<4; i++)
{
N_Ticket[3*i]   = stream[i]/100;
N_Ticket[3*i+1] = (stream[i]-100*N_Ticket[3*i])/10;
N_Ticket[3*i+2] = stream[i]-100*N_Ticket[3*i]-10*N_Ticket[3*i+1];
}
for (int i=0; i<13;i++)
{
  Serial.print(char(N_Ticket[i]));
}
for (int i=0;i<10;i++)
{
  Ticket[i]= char(N_Ticket[i]+0x30);
}
Serial.println("");
Serial.println(Ticket);
}

This works and I can generate a random number that will be used to print a Ticket. However, if I call this routine in an event related to the User Interface (hitting a button on my iPhone), Simblee looses communication and the software hangs up.
Does this mean that SimbleeRNG() cannot be used within the processing of an event?
Thank you for your attention

Support / Re: Simblee - optimal GPIO pin selection
« Last post by LulaNord on April 18, 2017, 09:00:59 AM »
Hi...as per my knowledge any issues with pin utilization. We have no idea how the pins are actually routed within the modules so just have to trust they are layed out well. The nRF5 pins are redefinable to make your board layout design easier. Well, except for the analog ones are fixed. And your right about wanting to keep GPIO[0-1] reserverd for programming.
