Sorry, the info you provided, means almost nothing. For some reason, hardware is not getting any messages from app side.
As I said, it works well on my hardware (Arduino leonardo + nrf8001). That’s strange.
Doesn’t sound like it’s worth any more effort on my part. Board goes back in the drawer…project scrapped.
I’m sorry to have disappointed you.
One more thing - include SPI.h, and it’s not a joke - when I include this, my project stops working.
I can’t explain it yet. Maybe there’s something wrong with Arduino IDE version, or the toolchain…
Do you plan to try using some other hardware?
You didnt disappoint…the hope of a BLE connected Blynk not yet working disappointed. 
As per my feedback…I get the same results when SPI.h is included.
Will check back in the future when its further along. Thanks.

Thank you for the hint!
For me, Blend micro works fine with
#define BLYNK_USE_DIRECT_CONNECT
//#include <SPI.h>

Hi there,
I´m trying to build my first project using bynk together with red bear blend micro
But I cant connect to the device at all.
When I run my project in blyk I get the message “device is offline”
My Andriod Note 3 does not see the bluetooth device.
at the serial monitor there is silence nothing at all.
As mentioned above I marked out // include spi.h
Now the bluetooth device is seen on my note 3 as “blynk”
But I get an error message " couppling rejected"
At the serial monitor there comes a message like:
[924473] Connecting…
But nothing more than that
When I run my blynk project there is the message again “device offline”
Is there any information (how to do) on how to connect blynk with blend micro ?
As usual, please try normal examples for your hardware (without blynk) and see if they work with your tablet.
There may be different incompatibilities…
My hardware works perfect when I use the BLE controller from Redbear.
But with blynk I have the situation as described.
Where do you see this message?
the message “device is offline” is at my Android phone note 3
The message [924473] Connecting… is at the serial monitor coming from the blend micro
I mean, this part.
It doesn’t look like you need to bind or couple devices…
Just select it from the blynk BLE widget.
also, try to remove the #define BLYNK_USE_DIRECT_CONNECT line
I do not couple or bind the devices
This was for information only.
I removed the #define BLYNK_USE_DIRECT_CONNECT line
and now I see at the serial monitor this:
[50737] Connecting…
[52822] Login timeout
[55820] Connecting…
[57903] Login timeout
[60903] Connecting…
[62986] Login timeout
[65986] Connecting…
In the blynk App I get the information “Device is offline”
Is there anyone ho runs the bynk together with the blend micro ?
Allow me one additional question (may be stupid but it is my first project with blynk)
Within the blynk app
My Devices
selection connection type
Which type should I select ?
“Bluetooth” or “BLE” ?
Let me check it, I have one Blend Micro board.
I checked it, and it works.
I will update an example soon, but it should work with just the SPI.h removed.
I use Arduino IDE 1.6.12 and latest BLE Peripheral library.
I use Arduino 1.6.13
on a clean system which means I removed every old Arduino Version and every old library
So I have only the red bear and the blynk stuff present in my library folder.
There are:
Blynk v0.4.1
nRF8001 Last updated: 2015/06/04
BLE_SDK_for_Arduino Release note 0.9.7:
BLE Peripheral library Version 0.3.1
Should I change something ?
I edit the “example” RedBearLab_BlendMicro
I removed SPI.h
But when i start the Blyn project I get only “Device is offline” (at my smart phone)
when I start the serial Monitor I get the this:
[10373]
___ __ __
/ _ )/ /_ _____ / /__
/ _ / / // / _ / '/
///_, /////_
/__/ v0.4.1 on Blend Micro
[10381] Connecting…
[16381] Connecting…
[22382] Connecting…
[28383] Connecting…
[34383] Connecting…
So, did you add BLE widget to your project?
What happens when you click “connect” in BLE widget?

with this library, you shouldn’t need BLE_SDK_for_Arduino and nRF8001 libs.
I yust edit my upper post and add the version of BLE Periphal
Must I remove the BLE_SDK_for_Arduino and nRF8001 libs ?
Because I need them for my other projects.
I´m not sure what you mean by
So, did you add BLE widget to your project?
What happens when you click “connect” in BLE widget?
I have done my first “Project” with in the Blynk APP
It is only one single button for testing
When I have done I could add a widget which includes the button I have defined
When I hit the button it toggles nothing more. ( of course the blend micro is still running near by to the laptop )
When I open the Blynk APP I can push the “play” Button in the upper right corner
Then I get the massage “Device offline”
Please Add BLE widget (find it).
click “connect” in BLE widget.

Sorry, may be it is my first time I do not understand you.
I found the widget with “my button” and placed it on my screen.
I can touch the widget and than “button settings” appear
but I do not find any “connect” option.
