I misunderstood! I did try to add a BLE widget (was looking into iphone widget)
So I tried again and it is able to find UART with BLE widget in first attempt but it does not connect. If i try a second time after failed it doesn’t find UART anymore. Then, when I launch the project, Blynk doesn’t tell me "device is offline"So I guess iphone is connected to the nrf800…
I also check again that I can connect and send byte with nRF toolbox provided by the manufacturer of nrf8001 and it works.
Following vhymanskyy’s link, I did restart the phone without success.
I really appreciate your help and I keep faith in a success!
I too am not able to connect the Adafruit nrf 8001 BLE. And today I got a bluetooth Bean from punchThrough. There’s an example sketch for the Bean in the blynk example folder, so I had my hopes up. But I can’t get it to work, either. Does anyone have ANY kind of bluetooth peripheral, breakOutBoard, BLE type device that they’ve gotten to work with iOS Blynk?
Another question, just in case :
I use Blynk exemple for nrf8001 in BLE connection.
Is that normal that my “Sketch uses 22898 bytes (70%) of program storage space.” (Arduino compiling quote)
It seems to be a lot for a simple exemple…
Hello all!
Do you have some news with adafruit nrf8001?
I just bought a hm-10 witch successfully connect to light blue app but still no luck with Blynk…
I’m starting to lose faith to use Blynk with iOS…
Just so that you know,
I’ve managed to successfully connect current Blynk iOS app with the Bluno from DFRobot.
The Arduino + HM-10 scheme seem to have difficulties.
I can now confirm that iOS app BLE works as expected. Please update you app to the latest version (should be 2.8.5) and if you still can’t connect, go to the app About page and send me the logs.
Please also make sure your sketch is correct. Double check:
RX and TX pins
Auth token
You path the correct instance of SoftwareSerial to the Blynk.begin() function
As example, here is my working sketch for Arduino+HM-10:
It’ll be here in 2 days, so I’ll let you know how it works. I still can’t get the nrf8001 to work, but if this HM-10 works, that’ll be terrific! I can build my project around it.
I tried your sketch witch and It is working great THANK YOU EUGENE!!!
It would be great to modify the blynk exemple, witch is slightly different.
First it was not working because it depends what baudrate your HM-10 is set!
For me, it was 115200, was not working with 9600.
You could find here a tutorial to change the baudrate :
I didn’t success with this so I did plug my HM-10 to an alexmos 32 board I had at home end Into the GUI, then go to board, Configure Bluetooth and you follow this guide :
Now It is working for me too! Thx for your time, hope this post is going to help IOS users!
First testing of the Hm-10 with IOS is a success! I tried the LCD, a button, and an analog input. If I power cycle the my uno/hm-10 the blink app sometimes doesn’t connect right away, but if I force it closed and restart, it always reconnects! Thanks so much! This opens a LOT of possibilities.
