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.
