iOS 9 communication throughput to TI SerialBLEbridge limited to 330~ bytes per second

Hi all.

I am working on an integration toward a piece of hardware that has the TI SerialBLEbridge installed as one of its components. I find that it only supports writing with response and that the throughput is limited to roughly 330 bytes per second. Is this the maximum throughput I will be able to achieve from new iOS devices with the TI SerailBLEBridge hardware, or will the manufacturer of the stand or I be able to improve upon the throughput.

I hope you'll be able to help.

Thank you in advance.

    Hello Rasmus,

    That seems a little low, even for iOS which traditionally limits to 6 packets per connection event (max). I would recommend taking a BLE air sniffer capture to understand the connection in more detail. Make sure you are using the fastest connection interval (~ 30ms default from iOS) and you are sending multiple packets per connection event, assuming you have the data queued on the Peripheral side.

    Best wishes
