I have updated the library and the App (iPhone) today but I am still getting āCanāt connect. Please retry or choose another device.ā I am trying this with the Blynk LED sketch.
@jlmyra Please donāt interject unrelated āme tooā issues into someone elseās topic. I have moved your issue into itās own topic.
Please clarify your issueā¦ what hardware are you trying to connect too?
Sorry for not following protocol.
I am trying to connect a Arduino 101 to my iPhone via bluetooth - BLE. I have a four motor robot that I have been operating with Blynk for some time. Recently, I am unable to get them to connect. I tried creating a new account, that didnāt help. I tried using the Blynk LED sketch with the new account. The arduino now shows up on the phone but it will not connect - it seems to time out and responds with āCanāt connect. Please retry or choose another device.ā I have installed the Blynk app on my phone that came out today (says it fixes BLE connectivity issues) and I installed the updated Blynk library.
What am I missing???
Thanks!
Jim
Hello. OK, so you are using an Arduino 101. Same issue then, sorry, it was hard to tell at first. Been seeing a few 101 questions mixed in with other BT/BLE issues.
Turns out there is a bug on Arduinoās / Intelās end, that is preventing Blynk BLE from working properly with the updated 101 core librariesā¦ or something like that.
āTheyā, Intel and Arduino, are aware of the issue. Unfortunately, I believe all 101 users will just have to wait until Intel releases the next update to the IDE.
Are known issues posted somewhere? I invested a lot of time trying to work around this issue.
Anyway thanks for your time and help!
Jim
For me it is simply a case of reading forum posts daily and hoping to remember the what, where and why as needed 
I am positive that the Blynk developers are sweating away at it as wellā¦ This latest update on the Intel issue was just posted by the developers earlier today, so we are not far behind the curve

I purchased an Arduino 101 to work with Blynk over bluetooth from my iPhone. I could not get it to connect so I searched and found this forum thread.
It seems the issue has been around for quite some time. The forum does not list timestamps but I assume this thread is a year old?
Looking at Intelās site, the last update to the 101 was 3/2016. That does not inspire confidence that they are looking into the issue.
I tried downgrading to 1.07 but the sketch will not upload. It just freezes. Is there any hope of getting Blynk working on my 101 over BLE or is it a lost cause? Any help would be appreciated. Thank you.
Every single post has a time date stampā¦ far right from your Avatar.
It is an Intel issueā¦ temporary solution is downgrade the Arduino 101 library AND firmwareā¦ More info about that in this topic.
Thanks Gunner! I appreciate the reply.
Regarding the timestamp I should have been more specific. It shows the month but not the yearā¦
I did not downgrade the Blynk library as I wasnāt sure which one to use. I may try that, but in the interim I added a WiFi module to my Arduino 101 and that is working for now.
Hopefully the wait will not be too long for the Intel fixā¦
Hover over it

NOT the Blynk Libraryā¦ the Arduino101 (Curie) library in the IDEā¦ check out that other post! Particularly toward the end.
