Does it support a maximum of 8 connections? i.e. 1 master and 7 slave concurrently?

Can you provide a sample project for this functionality?

This is an old thread, but S110 do now support concurrent Slave and Broadcaster roles (from version 7.0).

No official changes yet, but I'd recommend you to rather talk to your sales representative for information on future plans. Send me a PM with your location if you don't have his contact information.

This was half a year ago. Any news on this front?

Hi Daniel,

I have a similar issue myself in that our device uses broadcast but also needs to be "connectable" on an ad-hoc basis.

Luckily, we can get around the issue by controlling when and how long the connection from the smart device happens for. And luckily, not all of our customers require this particular function.

It would be nice to see the dual role support in the S110.

Hi Marc,

Thanks for answering and confirming. Completely agree with you - no need to stop non-connectible ads... hopefully in future software revisions it would be upgraded.

All other vendors I know don't have the wafer package option and the minimum footprint in plastic is at least 6x6 mm, which is too big for my project. So with some workarounds, nRF is probably still the best option for me, at least considering chips, which are available in commercial quantities at the moment.

It is perfectly legal in the Bluetooth 4.0 specification for the GAP to support multiple roles.

You are right that the specification calls for a Peripheral to only connect to one Central in the Peripheral-Central role relationship. But there's no reason why it has to stop "non-connectable" advertisements.

A certain other chip vendor even has demo code for this functionality.

The S110 does not support this. For information on S120, I'd recommend you to get in touch with your sales representative. If you don't have his contact information, please PM me with your location.

Hi,

Thanks for replying. I'm a still a newbie in BLE. For my project my peripheral device need to talk to 2 master devices simultaneously and since BLE only supports that a peripheral connects to 1 master at a time, the only possibility I found is to put the device in peripheral mode and at the same time broadcast some non-connectable advertising packets (this part of the connection will be "one-way").

Anyway as far as I know - BLE standard supports such and ever more complicated scenarios. They call it multiple state machines - i.e. part of the link layer is in connected state as peripheral and another part is in advertising state. However, all of this is implementation specific - i.e. I hope some of the Nordic specialists enlighten us on the subject.

Thanks.

A device is in peripheral role after (GAP) connection. A peripheral can connect to only one central, that leads me to decision: a peripheral can not be broadcaster on the same time.

i don't know the S210.
