Hello everyone. I am evaluating the nbew Alva Comfort 40 cell braile display, but I cnanot get it to bluetooth reliably with my iPhone 4S running the latest Ios8. The problem appears to be within the display, but I have noticed that in general, the 4S with the new operating system does not deal with braille very well. With respect to the Alva: conneciton either does not hold, or it locks during text extensive applications such as braille input of txt msgs. Hoping that others have had similar problems, have soled them and that they would be glad to share suggestions and solutions. It may be relevant: am awaiting delivery of an iPhone 6 so maybe my problem is just temporary.
