Can a s110 peripheral support simultaneous connections

[mohBOSS]

Hi all,

I am trying to connect a tablette (s110 peripheral role) to 5 S120 centrals simultaneously. I am using nrf51822, sdk6.1, s110 v7.0, s120 v1.0.1 . Is this possible ?

Thank you !

the device will stop advertisements once it connected to one device ...then how it will make multiple connections simultaneously...?

No, the S110 is only able to hold a single connection. It can however also do non-connectable advertising while in a connection, but these never lead to a new connection.

You could instead solve your problem by implementing a round-robin system of connections (e.g. by setting 5 devices in whitelist, then decreasing the whitelist count by 1 each time - or using directed advertisements). It is also possible to simply advertise data, if data transfer to the centrals is what is interesting to you.

Hi Ulrich, thank you for your reply. Is it possible to send a structure that contains mac address + rssi, in an advertising packet ?

[Ulrich Myhre]

You can send any data prefixed under the "Manufacturer specific data" flag. There are also a few officially adopted AD types for addresses, with mixed intentions. Look up the Core Spec Supplement PDF for a complete list. Especially 1.16 LE Bluetooth Device Address and 1.5 TX Power Level.
