peripheral.sendData very slow if NSData is larger than a few bytes about bluetoothkit HOT 5 CLOSED

Unfortunately you'll find that this is a limitation of Bluetooth LE, spiced up by further limitations applied by iOS to the throughput available to each application :)

That's unfortunate. Is a transfer time of 1-1.5 minutes for 250KB of data in line with what you've seen in the past? I tried slowly increasing the size of my file and it seems the slowdown is linear, so I don't think I'm doing anything especially wrong. Thanks for the fast reply, much appreciated!

Unfortunately, that sounds like very reasonable throughput. In previous iOS versions this was way worse. My suggestion would be to place the resource on some external location using a network connection and passing an address for it using the Bluetooth link. Of course I don't know your use-case so I'm just guessing away.

Unfortunately, the use-case requires transferring a binary file from a device with BLE but no internet connection to an iOS device, and THEN uploading the binary file to the web using the iOS device's internet connection. Doing a proof of concept using an iPad as the peripheral and iPhone as the central, so I have to pretend like the iPad has no network connection. Sounds like I'll have to temper the expectations for the transfer speed.

Thanks a lot for the insight and the great library, and especially the functional example project, much appreciated!

You're welcome. Feel free to ask again.
