s130 device connections

[FormerMember]

if i use s130 soft device will it do simultaneous master/slave role..... c1=central 1,c/p=centarl/peripheral,p1=peripheral.. assume c/p made a connection with p1 and it is transferring data to p1..at the same time will c/p made a connectable advertisement..? is it possible to c1 for scanning and connection to c/p and data transfer...? will c/p do sending and receiving packets at same time... ?

thank you

Hello,

here's what you can do with the S130 0.9 alpha:

• You can connect to 3 peripherals (your device will be the master)
• You can connect to 1 central (your device will the the slave)
• You can send advertisements at all times and you can scan at all times (no scanning in the short time while you try to set up a connection with another peripheral). However you can only send connectable advertisements while you are not connected to a central. As soon as you are connected to a central, you must send non-connectable advertisements.

Data transfer to all connected devices is possible in both directions. It does not matter if you want to send data to a central or a peripheral. The connections go in both directions and are not linked to the role that your device has (central or peripheral).

Good answer! To add a bit to this, the peripheral in the S130 has more packet buffers and therefore more throughput than the centrals. If you want to send and receive a lot of data (e.g. DFU) it is better to be the peripheral in that case.
