Production Application Guidance / Lenovo Tab 4 8 Doesn't find any Simblees
« Last post by MaMikee on January 13, 2018, 06:03:23 PM »
Just bought this for testing.  Running Android 7.1.1, Hardware Tablet TB-8504F Kernel 3.18.31

I have 2 Simblees running here, it finds neither of them using the Simblee for Mobile app.

If I go to the Bluetooth settings, it sees them both.  What gives?

Videos/Guides/Tutorials / RFDuino Cheat Card
« Last post by Somerled on January 12, 2018, 07:51:09 AM »
Hello.  I have been working with arduino for a few years now and always found the cheat sheets from the web to be very helpful.  I made this one from cut and paste of other based on the chips (nRF51822) pinout and posts in the forum.  For the most part it is just a collection of data from various sources.  Please let me know if there are any mistakes or changes you would like to see.
Thank you,

Trying to connect  a RFDUINO with LabVIEW with no success. Realize this post is old. I have a RFDUINO broadcasting temperature data and running an iPhone app. Has anyone got this to work. Neither this forum or the National instruments forum has shown solutions
Hi Nelson,

thanks for your reply!
Your example works and I realized that my current measurment setup was the cause for the confusing behaviour I wrote in the last posts. I was not aware, that the "SimbleeCOM.begin()" is drawing a current of approx. 16mA! My shunt resistor was too high which caused undervoltage. So I have to apologize for the wrong and missleading current measurements and conclusions in the last posts!

But my initial question is still valid.
I have now tested SimbleeCOM and it seems that it is a must, to have SimbleeCOM.begin() called and it is not possible to have a working SimbleeCOM_onReceive() callback during Simblee_ULPDelay(). Which by the way would reduce the current only from 16mA to 13mA.

So my new formulation of the question:
Is it possible to have a listening SimbleeCOM callback with current draw <<1mA ?
If not with your current api, maybe with some low level "hacks"?

Best regards,

I bought this yesterday to do different screen size testing.

When I go to the App store, I can search for "Simblee" and it suggests "Simblee for mobile".  I select that and get "No Results for "Simblee for mobile""

What's going on?

Thinking this through a little better if RFD will give me what they submitted to Apple/Android and I can just change the logo then I'm interested.

No disrespect intended but if I were interested in that I wouldn't be using your silicon.

As I mentioned in our email discussion, you can absolutely build your own BLE app and submit to the app stores.   

I am testing using this sketch:

Code: [Select]
char payload[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 };

void setup() {
  SimbleeCOM.mode = LOW_LATENCY;

void loop() {
  SimbleeCOM.send(payload, sizeof(payload));

void SimbleeCOM_onReceive(unsigned int esn, const char *payload, int len, int rssi) {

The Simblee goes into ULP mode as expected drawing 4uA. With this sketch, are you seeing different behavior?

I've been told away from this forum that this won't happen.  While I'm disappointed, I can see why the company would want everyone to see their product name.  Helps your competition know something about how you made your product so RFDigital can sell more silicon.
