SD130 restriction: 1 connection as slave and 3 connections as masterhttps://devzone.nordicsemi.com/f/nordic-q-a/5388/sd130-restriction-1-connection-as-slave-and-3-connections-as-masterHello, where do the SD130 limitations come from. Is it the Bluetooth standard that limits a device to 3 connections as a master and one connection as a slave or is it a limitation because of the needed scheduling in the SoftDevice itself?

We now have a 32kB version, which is less restricting, so let’s see what happens.</p><div style="clear:both;"></div>RE: SD130 restriction: 1 connection as slave and 3 connections as masterhttps://devzone.nordicsemi.com/thread/18819?ContentTypeID=1Mon, 02 Feb 2015 11:16:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0b274a54-7024-4da9-a74e-dcecfd2780c8Eirik Aa<p>BLE central ( S120 ) can support 8 connections. I think the state of the SW stack for the S130 have got gotten only so far that it can handle than 3 central connections. There is no such limitation in the BLE definitions.</p> <p>Nordic have hinted on plans for 1 periferial and 7 central uppgrade of the S130 later but not at this stage.</p> <p>Eirik</p><div style="clear:both;"></div>
