This changed in S132 v4.

did this change with SDK 14 / SD 5.x ?

Philip

Why are you connecting? Is data being written to your BLE device or just being read.

If its just being read, you would be better off just putting the data into the advertisement, even if that means sending different data in each advertisement.

With our current SoftDevices (except the s132 4.0.0-2.alpha) you cannot do connectable advertising while you are in a connection, so I don't see how you can do what you describe.

Hi, Petter. I actually want to do connectable advertising that can be connected to, even while my peripheral is already connected to a central.

I'm not trying to allow connection to multiple centrals. I just want to simplify using the peripheral with multiple centrals.

The peripheral would send connectable advertisements even while connected. We might also send status info as manufacturer-specific data indicating whether the peripheral is already connected and if it can drop the connection.

If a second central tries to connect to the peripheral, the peripheral would, depending on its state, disconnect from the first central to connect to the second.

Thanks for the link to the nRF52 project. I'll take a look at it. Supporting multiple logical peripherals could be an option, but it's not exactly what we were thinking of. And we're using the nRF51.

So you want to do connectable advertising that can't be connected to? Doesn't sound like you are following the spec... However, the BLE spec allows having multiple connections as a peripheral, we actually have an alpha that supports this for the nRF52, see this for more information.

Could you explain a bit more about your application? What do you achieve by doing this?
