Re: profiles for BLE

Hi Viet, The Core Bluetooth Framework allows you to implement your own profiles. It does not limit you to just the Bluetooth SIG defined profiles. This was one of the design goals for Core Bluetooth and it has been received very well by the industry.

> But that wouldn't have been BLE then ; as the scope is restricted to iPhone 4S, iPad 3 and MBA Correct -- I don't have experience with Bluetooth 4, but I wouldn't be surprised if these issues are still relevant. _______________________________________________ Do not post admin requests to the list.

> Secondly, in your experience Joachim, what is the maximum distance usually > seen at which the connection is still working (BLE specs state 50m but could > never verify this value myself) In my experience there is no consistent distance -- it varies greatly between device pairings (i.e., host computer and mobile device combinations). For instance, I recall an iPod touch was capable of maintaining a connection with a Mac Pro after twisting around several hallways in my office building, while a first-generation iPhone could barely maintain a connection 10 meters outside my office. Changing the host computer has similar effects on connection range. I ended up hard-coding some maximum RSSIs for certain host computer/mobile device combinations, but that's obviously kludgy considering how many combinations there are. _______________________________________________ Do not post admin requests to the list.

Re: connecting a BLE device problem

Hi zz_zhang, That is correct. The connection request will be pending until you cancel it. This can be quite useful if you want to connect to a device as soon as it comes within range. There is no timeout on connection requests. The system tried to connect to the peripheral for as long as you want (days, months, years) or until you cancel it.

If the BLE device advertizing timeout and I press the connection button. of course, the connection can not establish. After a shot time, if I make the BLE device in advertizing, the connection automatically establish without a button pressing. > Is it correct? sorry for my poor English! > > zz_zhang > _______________________________________________ Do not post admin requests to the list.
