Change connection interval ?

[natcl]

Hello,
I'm trying to implement the Apple BLE MIDI Service.

In the documentation they state this:

The accessory shall request a connection interval of 15 ms or less. Apple recommends starting with a request for a connection interval of 11.25 ms and going to 15 ms if the connection request is rejected by the Apple product.

Is there a way to set this in bleno ?

Thanks

Hi @natcl,

This is not supported at the moment, I'm marking it as an enhancement.

We could have an API similar to CoreBluetooth's setDesiredConnectionLatency with values low, medium, and high.

Thanks, and what would be the default connection interval now ? Is it the same as the 100ms advertising interval or once a connection is established it's faster ?

I believe it's determined by the central device, you can use sudo hcidump -t -x to see what is specified. Please let me know what it reports on your system.

In my case the central device is my iPhone I believe, the peripheral (using
bleno) runs on MacOS.

You can use the Packet Logger app that is part of Xcode Hardware IO tools to see what's going on then.

Thanks will try that !
So far speed seems good so I assume nothing more is needed in bleno.

@natcl excellent, let's leave this request open for now to see if other people request a similar feature.

Hello!

I'm working on transmitting small files from a Raspberry Pi to an Android. Being able to increase the connection interval would be extremely helpful to speed up transfer.
