Packets per interval for Bluetooth MIDI
by Keith Nagle 29 Jun '15

29 Jun '15

I am developing a BLE MIDI device using a TI CC2541 chip. I am observing a 15ms connection interval with 3 packets sent per connection when paired with an iOS device. I am using overlapped processing on the TI board, but it doesn’t seem to make a difference if this is enabled or not. Does anyone know if 3 packets is a hard limit when pairing a BLE MIDI device to iOS? It doesn’t seem to make a difference how big or small (within MTU limits) the packets are, 3 seems to be as many as I can transmit. All the best, Keith. _______________________________________________ Do not post admin requests to the list. They will be ignored.

advertising name between iOS and OSX
by Roland King 19 Jun '15

19 Jun '15

My testing seems to show the following difference between iOS and OSX, can anyone else confirm these results and/or tell me how to make it more consistent I have some development code (on a nordic board) which allows me to switch between a long / short or no name at all, in the advertising packet. So I run that and mess with it. On OSX 1) There’s no name in the advertisementData returned in the didDiscoverPeripheral, ever. 2) The CBPeripheral.name property alway contains the ‘best’ name. ie if no name has been seen, it contains nil, if a shortname has been seen, it’s that, if a full name has been seen, it contains that. Even if you change the name from long to short, or missing in the advertising packet, OSX continues to report the same name. Only if you give it a ‘better' name does it update. 3) Even though I’ve asked *not* to have duplicate notifications, I get constant callbacks for the same devices, every second or so On iOS 1) There’s always a name in the advertisementData packet, as long as you’ve provided one in the actual advertising packet 2) The CBPeripheral.name updates when you change the name in the advertising packet between long/short/missing. However, once it’s seen a name, it never goes back to having nil, but if you switch from a long to a short and vice-versa, it will update 3) I only get the one callback each time the device is ‘seen’ unless I change the advertising data, at which point I get another one. Seems odd to me they have such different behaviour. _______________________________________________ Do not post admin requests to the list. They will be ignored.
